Summary

Nepenthes siamensis, a new species from Khlong Phanom National Park in southern Thailand, is described. This species, closely related to others in section Montanae, stands out due to its distinct inflorescence characteristics, including bracts present on both male and female flowers, and unique pitcher morphology. It is found approximately 650 km north of the most similar species based on morphological comparison, N. sanguinea and N. thai, which are also both terrestrial and lower montane. It shares characters with them, such as a climbing habit and oblong to subspathulate leaves with 2 – 3 longitudinal nerves on each side of the midrib. This discovery significantly extends the known range of section Montanae.

Abstract

A new species of Nepenthes—Nepenthes erucoides—is described and illustrated from a single ultramafic peak in the Dinagat Islands Province of northeastern Mindanao. It is a distinctive component of a relatively low-elevation, highly biodiverse montane elfin forest that has evolved in association with a particularly thin and extremely hostile substrate. Plant habit, and leaf, inflorescence, indumentum and peristome-column morphology appear superficially similar to those of the ultramaficolous montane species of Palawan, implicating an environmental basis for a syndrome of shared characteristics.

Taxonomy

 Nepenthes erucoides A.S.Rob. & S.G.Zamudio, sp. nov. 

Etymology:— The specific epithet erucoides is derived from the Latin eruca (caterpillar) and the Greek suffix – oides (resembling), in reference to the densely hairy developing leaves which, when still appressed within the petiolarlaminar groove of the preceding leaf, resemble the exuberantly hairy caterpillars of certain erebid macromoths from the subfamily Arctiinae, such as those of the genus Arctia Schrank (1802: 152) [e.g. Arctia opulenta Edwards (1881: 38)].

Abstract  

Utricularia damingshanensis (Lentibulariaceae), a new species from Guangxi, China, is described and illustrated. It resembles U. caerulea and U. warburgii but differs in having a corolla palate with four hooked processes on the distal margin; lower calyx lobe distinctly shorter than the upper; distinctly striped corolla with 8–15 deep violet lines on the lower lip and 6–9 radiating lines on the upper lip, as well as a helmet-like swelling at the base of the lower lip. Phylogenetic analysis based on nrITS, rps16, and trnD–trnT strongly supported its placement in sect. Nigrescentes as sister to U. warburgii. Both morphological and molecular evidence support its status as a new species.

Abstract

Nepenthes megastoma is described and illustrated as a new species from the Puerto Princesa Subterranean River National Park, a UNESCO World Heritage Site in Palawan Philippines. This carnivorous tropical pitcher plant is currently known from just three locations in the Mount Saint Paul karst formation, where it grows on vertical limestone walls. Morphologically, N. megastoma is characterised by its highly branched stems, campanulate pitchers, peltate tendril exsertion, dimorphic upper pitchers, and unidirectionally upturned female flowers. It is assessed as Critically Endangered under the IUCN Red List criteria, based on its restriction to three subpopulations comprising few total individuals. Pitcher morphology suggests a degree of ecological-functional convergence with N. campanulata of Borneo, though overall morphology indicates a probable close affinity with the widespread Palawan endemic N. philippinensis.

Diagnosis:—Nepenthes megastoma superficially resembles N. campanulata but differs in the production of (differences in parentheses): large growths, individual stems to 2.8 m long and 1.2 cm in dia., branching basally or medially to form pendent clumps to 10 m long (to ~35 cm, mostly basally branching to form short clumps, stems to 0.4 cm dia.), phyllodes elliptic-subobovate and 20–38 cm long with shortly decurrent base and slight abaxial basal swelling (spathulate-lanceolate, to 9 cm long, base amplexicaul without swelling), pitchers trimorphic, comprising uniform lower pitchers and two forms of upper pitcher (pitchers monomorphic), pitchers brittle, peristome pronounced, to 5.5 mm wide, lid ±suborbicular, to 5 cm dia. (pitchers flexible, peristome very narrow, typically ≤ 2 mm, lid ovate-elliptic, to 2 cm long), inflorescences to 48 cm long, partial peduncles dense, mostly 2-flowered, female flowers ascending, unidirectionally upturned (Fig. 6f) but borne on pedicels evenly distributed about rachis (inflorescences ≤ 20 cm long, lax with few flowers, partial peduncles mostly 1-flowered, female flowers spreading, not unidirectionally upturned), and an indumentum of dimorphic trichomes present on most surfaces (almost entirely glabrous except below peristome and around spur).

Etymology:—The epithet megastoma is constructed from the Greek-derived prefix mega- (large) and the Greek word stoma (mouth), meaning ‘large mouth’, a reference to the diameter of the pitcher opening, which is greater than that of the rest of the pitcher in all pitcher forms.

[Botany • 2025] Pinguicula panfetiae (Lentibulariaceae) • A New Caribbean Butterwort from eastern Cuba

 

Pinguicula panfetiae Panco, P.Temple & Y.Domínguez,

DOI: doi.org/10.5091/plecevo.161641

Abstract

Background and aims – Pinguicula is a cosmopolitan genus of carnivorous plants with more than 100 species, most of them distributed in two centres of diversity: Europe and the Central American-Caribbean region. Fourteen species are reported for Cuba. During fieldwork to study Pinguicula populations in eastern Cuba, a white-flowered taxon, previously misidentified as Pinguicula albida or Pinguicula jaraguana, was collected in the mountainous regions of the Alejandro de Humboldt National Park. This taxon represents a new species for which we present a full description, a distribution map, illustrations, photographs, and a conservation status.

Material and methods – Living and preserved material of several populations of white-flowered Pinguicula from Cuba were analysed, measured, and described based on vegetative and reproductive characters. Statistical analyses were carried out to explore the differences among the collections. The preliminary conservation status of the new species was assessed based on the IUCN guidelines and criteria.

Key results – Pinguicula panfetiae is described as a new species endemic to eastern Cuba. It thrives on permanently wet, ferritic soils derived from serpentine bedrocks, on slopes above the banks of the River Toa in association with surrounding semi-arid montane serpentine shrubwood (charrascal). It differs from the closely related species, Pinguicula albida and Pinguicula jaraguana, primarily by its smaller rosettes with obovate, suberect to erect leaves, non-involute leaf margins, smaller flowers up to 1–1.3 cm including the spur, longer (0.6–0.7 mm) and wider (0.18–0.22 mm) seeds, and that it grows in full sun.

Conclusion – The newly described species increases the number of Pinguicula in the Cuban archipelago to 15. Pinguicula panfetiae is preliminarily assessed as Critically Endangered (CR) according to the IUCN Red List Categories and Criteria.

Abstract

Background: Mexico harbours the highest species richness of Pinguicula, with 54 species. Plants collected on gypsum soils in Oaxaca do not coincide with any known species.

Questions: Do plants collected represent a new species? What is its conservation status? How many Pinguicula gypsophytes are there in Mexico? How are they different? Where are they distributed?

Studied species: Pinguicula gypsophytes.

Study site and dates: Santo Domingo Tonalá, Oaxaca, Mexico, 2023-2024.

Methods: A morphological analysis and description were made based on herbarium specimens and living plants. We employed Bayesian Inference and Maximum Likelihood to analyse the regions rpl32-trnL, trnQ-rps16, and ITS to infer their phylogenetic position concerning similar species. The conservation status of the species was assessed following the IUCN Red List Criteria and Categories. Gypsophyte specimens of Pinguicula in Mexico were examined to construct a key. The species richness distribution of gypsophyte Pinguicula was analysed by state, physiographic provinces, and 1 × 1° cells.

Results: Pinguicula tonalaensis is proposed as new species distinguished by linear-lanceolate summer leaves, geniculate corolla tube, and without propagules in the apex of summer leaves. Pinguicula tonalaensis is sister of the clade P. heterophylla-P. medusina and together form a monophyletic group. Pinguicula tonalaensis is Critically Endangered. There are 10 gypsophytes of Pinguicula in Mexico. Nuevo León and the Sierra Madre Oriental are the richest. The location of the cell richest coincide with these.

 

Conclusions: The morphology and phylogenetic hypothesis support Pinguicula tonalaensis as new species. This increasing the taxonomic richness of Pinguicula in Mexico to 55.

Keywords: carnivorous plants , Mexican Transition Zone, Oaxaca, Pinguicula diversification, gypsum soils

Pinguicula tonalaensis López-Pérez & Zamudio sp. nov.  

Diagnosis. Pinguicula tonalaensis shares winter and summer leaf forms and size with P. medusina. The geniculate corolla tube and the lack of apical propagules on the summer leaves set P. tonalaensis apart.

Abstract

A new species of Drosera—Drosera albonotata—from the western Wheatbelt (Western Australia) is described and illustrated. The taxon, which is largely restricted to sandy clay loam soils in Wandoo woodland and shrubland, is morphologically similar to D. miniata and D. coomallo but can be distinguished by its distinct floral features and ecology. A distribution map of the new species and its allies and a revised and updated diagnostic key to the twelve recognised orange-flowered pygmy Drosera in Western Australia are provided.

 Type:— AUSTRALIA. Western Australia: Wandoo National Park, ....

 Diagnosis:— Drosera albonotata is similar to D. miniata from which it can be distinguished by (contrasting features in parentheses) 1) its petals, which are pandurate (broadly obcuneate-obovate to obovate-subpandurate) and bear white, basal patches on either side of the midvein that are apparent both on the adaxial and abaxial petal surfaces (basal petal patches uniformly maroon-black), with more prominent venation including secondary and tertiary branching (less prominent, mostly limited to secondary branching), 2) its anther filaments, which are black at the base graduating to maroon-purple towards the thecae (filaments entirely white), 3) its sepals, which are apically more obtuse (more ovate) and inflorescences, both of which are distally more densely glandular than those of D. miniata, 4) by its more elliptic laminae (sub-orbiculate) with an average of five Type II unifacial marginal glands (seven Type II unifacial marginal glands), the abaxial surface with a greater density of eglandular trichomes.

 

 A pollinator of Drosera albonotata, identified as a Melolonthid (Scarabaeidae) possibly in the genus Liparetrus (photograph by A.S. Robinson).

 

Etymology:— the specific epithet albonotata is derived from the Latin albus (white) and notatus (marked), a reference to the two basal marks of white on each petal, the overall effect of which is a collar of white around the floral centre. This feature is wholly absent from Drosera miniata.
