DOI: 10.3897/phytokeys.247.130241

Abstract

During a survey by the National Tropical Botanical Garden drone team, an enigmatic Schiedea was observed in December 2021on steep, rocky cliff faces of the Waiahulu Valley in the Waimea Canyon of Kaua'i. Subsequently, another survey was conducted in March 2022 and, by use of a remotely controlled cutting device suspended below the drone, the first herbarium specimen was collected, as well as a seed collection of an undescribed cliff-dwelling species of Schiedea. Detailed study of the collections and plants grown at the University of California, Irvine greenhouse showed that it had enlarged, somewhat whitish sepals similar to those of cliff-dwelling S. attenuata (the sole species in sect. Leucocalyx), yet differed significantly from all other species in the genus. It also shares with S. attenuata a woody habit, hermaphroditic flowers, coloured nectar and styles 5 to 7 or 8. We describe it here as S. waiahuluensis given the only known localities are on the cliffs of this valley and place it in an enlarged sect. Leucocalyx. With the discovery of this new species, there are 36 species in this Hawaiian endemic genus.

[Botany • 2024] Bufonia darvishii (Caryophyllaceae) • A Novel endemic Species from Zagros Mountains, Iran

 

Bufonia darvishii Zeraatkar,     

in Zeraatkar, 2024. 

DOI: 10.1111/njb.04440

Abstract

A new subalpine species of Bufonia sect. Longipedicellata from the Zagros Mountains in west Iran is described and illustrated here. It colonizes mountain slopes with gravelly, stony, and scree substrates in one locality of Chaharmahal and Bakhtiari province, preferably with a western and north-west orientation, at elevations between 2700 and 3100 m a.s.l. The new species, B. darvishii, is diagnosed against the morphologically similar B. macrocarpa. The two species share similarities such as filiform and long pedicels, a lax panicle-cyme inflorescence, distribution pattern of trichomes, and long peduncles. However, the new species stands out with semi-shrub life form, its greater height, retention of the previous year's stems, cymes bearing more flowers, orbicular petals, larger petals, a broadly ovate ovary, larger sepals with more pronounced nervation, shorter pedicels, larger flowers, etc. Bufonia darvishii is proposed to be Critically Endangered (CR) following the guidelines of the IUCN.

Bufonia darvishii Zeraatkar sp. nov.  

Diagnosis: A species related to Bufonia macrocarpa Ser. but exhibiting a significantly greater height (30–50 versus 20–35 cm), semi-shrub life form (versus erect chamaephyte), while retaining previous year's stems, longer leaves (up to 13 versus up to 10 mm), cymes bearing more flowers (10–25 versus mostly 3–10), orbicular petals (versus ovate or obovate), larger (3.0–3.5 mm in diameter, versus (1.5) 1.8–2.0 (3.0) × 1.5–2.0 mm), and broadly ovate ovary (versus elliptic or rounded) petals, different petal length/filament length ratio (shorter versus longer), larger sepals (2.5–3.0 × 1.0–1.6 versus 1.5–2.0 (3.0) × ca 0.8 mm) and with more pronounced nervature (7–9-veined versus 3–7-veined), shorter pedicels (up to 15 mm versus up to 30 mm), and possessing larger flower (ca 5–6 mm in diameter versus 3–4 mm).

 

Etymology: The specific epithet honors Mohammad Darvish, a desert researcher from the Research Institute of Forests and Rangelands, and an Iranian environmentalist who has made comprehensive and diverse efforts to preserve the environment in Iran. His environmental leadership includes the protection of ecosystems, plant and animal species, as well as the reduction of waste and pollution. He and like-minded associates are primarily directed towards recognizing and addressing how actions related to environmental protection can impact human health and well-being.

[Botany • 2023] Silene isabellae (Caryophyllaceae) • A New Campion Species from Serpentine Soils of Albania

Silene isabellae Selvi & Bianchi, 

in Selvi, Gonnelli et Bianchi, 2023.

 DOI: 10.3897/phytokeys.227.100850

Abstract

The new species Silene isabellae is described and illustrated from the Skënderbëut mountain range of central Albania. It grows on the ultramafic mountain slopes around Qafë Shtamë, in the understorey of open Pinus nigra forests and in the rocky grasslands above the forest belt, at 1000–1600 m a.s.l. Silene isabellae is a serpentine endemic likely belonging to section Elisanthe (Fenzl ex Endl.) Ledeb. and shows affinities with the widespread European species S. noctiflora L. It is sharply distinct from the latter species in habit, stem and leaf pubescence, morphology, and biology of the flowers and length of the carpophore. Moreover, the ecology of the two taxa is also contrasting, being S. noctiflora a synanthropic-ruderal, mostly in lowlands. Weaker similarities were also observed with the south European subalpine taxa of the group of S. vallesia L. of section Auriculatae (Boiss.) Schischk., though these are not likely to reflect a real systematic affinity.

Diagnosis: Silene isabellae differs from S. noctiflora by the perennial habit with stoloniferous stems forming thick mats (instead of annual), the sparsely and shortly glandular-pubescent stem (vs. densely hairy), the basal leaves of the sterile stems present and widely obovate-spathulate (vs. absent), the cauline leaves linear-lanceolate (3–5 mm vs. ovate-lanceolate 25–35 mm wide), with shortly ciliate margins (vs. densely pubescent on both surfaces), the longer calyx teeth (ca. 8.5 vs. 7.0 mm), the corolla unscented and open during daytime (instead of scented and opening at evening), the petal lobes dentate (vs. entire), the fruiting calyx with prominent longitudinal ribs and the longer carpophore (6–7 vs. 2–3 mm).

 

Etymology: This species is dedicated to the first author’s wife, for her continuous support and advice during many botanical trips across the Mediterranean and the Middle East.

[Botany • 2023] Silene ophioglossa (Caryophyllaceae: Sileneae) • A New Species from southwest China

 

Silene ophioglossa Huan C. Wang & Feng Yang,  

in Yang, Wang, Wang et Wang, 2023. 

 DOI: 0.3897/phytokeys.225.98247

Abstract

Silene ophioglossa Huan C. Wang & Feng Yang, a new species of Caryophyllaceae, is here described and illustrated based on morphological and molecular evidence. The new species was found in Sichuan and Yunnan provinces, southwest China. Phylogenetic analysis based on ITS sequences showed this new species belongs to section Cucubaloides. Morphologically, it resembles S. phoenicodonta and S. viscidula, which were also found in the southwest China, but clearly differs from the latter two species by having 5–7 mm long calyces with sparsely hirtellous and short glandular hairs, white petals, linear limbs and lobes, and absent or oblong-linear coronal scales. A distribution map and a table with morphological diagnostic characters of new species and its closest relatives are provided, as well as a preliminary conservation assessment of S. ophioglossa under the IUCN criteria.

Diagnosis: Silene ophioglossa is morphologically similar to S. phoenicodonta (Fig. 3), but clearly differs from the latter in having 5–7 mm (vs. 6–8 mm) long calyces sparsely hirtellous and short glandular hairs (vs. densely hirtellous and with short glandular hairs), white (vs. dark violet) petals, linear (vs. obovate) limbs and linear (vs. ovate or nearly band-shaped) lobes, absent or oblong-linear (vs. orbicular-linear) coronal scales.

Etymology: The specific epithet “ophioglossa” is derived from the Greek words “ophis” (meaning snake) and “glossa” (meaning tongue), which refer to the petal lobes of this new species which resemble the tongue of a snake.

 Silene vanchingshanensis C.Y.Wu ex Huan C. Wang & Feng Yang, sp. nov.

Diagnosis: Silene vanchingshanensis is similar to S. morrisonmontana, from which it differs by its shape and size of leaves (linear-oblanceolate, 3–6 cm × 3–6 mm vs. linear, 2–7 cm × 2–3 mm), cymes (often 2–5-flowered vs. usually solitary) and colour of petals (pink or violet vs. white).

Etymology: The specific epithet vanchingshanensis is derived from the type locality “Vanchingshan”, a variant name for Fanjingshan Mountain.

Distribution and habitat: Silene vanchingshanensis is currently known only from locus classicus (Fanjingshan Mountain), a famous scenic resort in Guizhou, southwest China. The species grows on cliffs or rock crevices of the mountain summit at elevations of 2,100–2,500 m.

Abstract

Ametrodiplosis Rübsaamen (Diptera: Cecidomyiidae: Clinodiplosini) is a mostly Holarctic gall midge genus whose species are associated with a wide range of seed plant families, either as gall-inducers or inquilines. In this study, we describe three species of Ametrodiplosis from Japan: Ametrodiplosis adetos n. sp. feeding in the flowers of Tylophora aristolochioides Miq. (Apocynaceae); A. aeroradicis n. sp. inducing aerial root galls on Trachelospermum asiaticum (Sieb. et Zucc.) Nakai and T. gracilipes var. liukiuense (Apocynaceae); and A. stellariae n. sp. forming leaf bud galls on Stellaria uliginosa Murray var. undulata (Thunb.) Ohwi (Caryophyllaceae). A molecular phylogenetic analysis using mitochondrial COI and ribosomal 16S genes and nuclear ribosomal 28S gene were conducted for the three new Ametrodiplisis species and other clinodiplosine taxa sequences available in GenBank. The analysis supported the monophyly of Ametrodiplosis despite the variable life history of the three species. In addition, it indicated very low intraspecific genetic divergence among the individuals from different localities and/or host plants. A taxonomic key to the three new Japanese species of Ametrodiplosis is provided.
