[Botany • 2025] Columnea flavohirsuta (Gesneriaceae) • A New Species from the Chocó Biogeographic Region, and an Update on Some Columnea Circumscriptions

Abstract

Recent field expeditions in the Chocó Biogeographic Region on the western Andean slopes of northwestern South America, as well as ongoing herbarium research, have led to the discovery of a new species of Columnea L. (Gesneriaceae) and prompted circumscriptions to be updated for some Columnea species. A new species, Columnea flavohirsuta J. L. Clark, is described and differentiated from a complex of morphologically similar species including C. minutiflora L. P. Kvist & L. E. Skog and C. herthae Mansf. The name C. parviflora C. V. Morton is recognized as a heterotypic synonym of C. herthae. The name C. tenensis (Wiehler) B. D. Morley is recognized as a heterotypic synonym of C. illepida H. E. Moore. The name C. reticulata Amaya-Márquez, L. E. Skog & G. E. González is recognized as a heterotypic synonym of C. purpureovittata (Wiehler) B. D. Morley. The taxonomic history of these species is discussed, and field images are provided to serve as aids for identification and a guide for future systematic studies of Columnea.

Abstract

An elegant new species of Fagaceae, Lithocarpus graniticus S. P. Chen & Y. Z. Lin, was discovered in the valley of a granite mountain in southern Fujian, China. The new species is most similar to L. cucullatus C. C. Huang & Y. T. Chang in having grayish-white waxy scales on abaxial leaf surfaces, cupules enclosing more than 1/2 of the nut, and the seed scar convex and ca. 1/3 of the nut. It is distinguished by its cupular cupule, relatively densely pilose inflorescences, ovate or ovate-elliptic leaves, and sparsely pilose indument on branches and abaxial surfaces of young leaves. Photographs, a line drawing, and a description of the new species are provided.

Diagnosis. Lithocarpus graniticus S. P. Chen & Y. Z. Lin is distinguished from L. cucullatus C. C. Huang & Y. T. Chang by its sparsely pilose (vs. tomentose) branchlets and abaxial surfaces of young leaves; ovate or ovate-elliptic (vs. narrowly oblong to lanceolate) leaves; relatively densely pilose (vs. to-mentose) inflorescences; and cupular (vs. cucullate) cupules.

Etymology and common name. The epithet “graniticus” indicates the new species was discovered growing in granite mountains. 

The proposed Chinese name of Lithocarpus graniticus is 岩柯 (yan ke).

Abstract

Recent field expeditions to the Upper Magdalena Valley of Colombia resulted in the discovery of a new species of Columnea L. (Gesneriaceae). Columnea conopurpurea J. L. Clark, Y. Ramos-Arias & J. L. Peña, sp. nov., is described as a narrow endemic from the Colombian Massif in southern Colombia. The new species is an epiphyte with pendent shoots, shallow bilabiate corolla tubes, and a purple elongate cone-shaped berry. An overview of fruit shapes throughout Columnea is summarized to demonstrate the uniqueness of the purple cone-shaped berry in C. conopurpurea. Description, distribution map, illustration, and field images are provided. Based on IUCN guidelines, a preliminary conservation status of Endangered (EN) is provided for C. conopurpurea.

 Abstract  

We describe and illustrate a new species of Matelea Aubl. from Península de Nicoya, Costa Rica. Matelea nicoyana J. E. Jiménez, M. Méndez & J. A. Obregón is morphologically similar to M. pseudobarbata (Pittier) Woodson but is distinguished by its stems with dispersed, pilose trichomes, leaf blades without pilose trichomes and with 12 to 15 colleters, calyx lobes deltate, inflexed, and corolla with reflexed and contorted lobes covered by white-translucent, flexuous trichomes adaxially. Data on its distribution and habitat, phenology, conservation status, and morphologically related species are given and photographs are presented. A dichotomous key is presented for species from Costa Rica sharing similar indument. The species proposed here increases the number of Matelea species in Costa Rica to 17, nine of which are endemic.

Abstract

Piper alwynii M. A. Jaram. (Piperaceae), a new species occurring in sandstone outcrops of the Cordillera del Cóndor at the border of Ecuador and Peru, is here described and illustrated. Morphologically it shows similarities to species in the Radula clade. Piper alwynii is similar to P. purdiei C. DC. but differs in having leaves pinnately nerved within the lower two thirds of the midvein, nerves pubescent on the abaxial surface, villous peduncles, and spikes 2–2.7 cm long. An identification key for 32 northern South American Piper L. species with small (≤ 10 cm) leaves is presented.

Abstract

A new species of Hippeastrum Herb. (Amaryllidaceae) from the department of Amazonas, Peru, is described and illustrated here. Hippeastrum peruvianum Meerow & Campos-Rocha features floral morphology unique among the other species of the genus occurring in the country. It has similarities with H. miniatum (Ruiz & Pav.) Herb. and H. reginae (L.) Herb. but is distinguished readily by its larger flowers, distinct coloration pattern, and trifid stigma. The new species is known only from the type collection by Paul C. Hutchison in 1958. It was determined as H. miniatum in error and has apparently been widely cultivated, especially in California, either under that name or erroneously considered a hybrid. We additionally observe that H. ugentii Ochoa, described from Peru and later transferred to Crinum L., is the naturalized South African species C. moorei Hook. f.

Etymology. The species is named for its conspicuously and rather narrowly abaxially indented cup-shaped floral tube (hypanthium/floral cup/calyx tube; see Tillett, 1988), leading to a conspicuously expanded base of the androgynophore and a hidden attachment of the floral stipe (pedicel) into the flower. Literally, a chalice-shaped calyx, a play on words.

A new species of Piper L. (Piperaceae) from the eastern slopes of the Andes in Colombia and Peru, P. callejasii W. Trujillo & M. A.

Piper callejasii is distinguished by its stigmas being sessile, rather than on a long style as in four similar species. Its conservation status is suggested to be Endangered.

Etymology. This species is named in honor of Ricardo Callejas. Ricardo has worked on Piper taxonomy for more than three decades. Not only is he immensely knowledgeable about species in the Neotropics (mostly) and Asia (some), but he has been incredibly instrumental in empowering young botanists, like us, to study Piper in an integrative manner. Christiane Ehringhaus called him the “Pope of Piper” (Ehringhaus, 1997); we prefer the “Father of Piper” because of his knowledge and warm welcome to anyone dedicating time to study these captivating plants.

 Abstract

Petrocodon anoectochilus F. Wen & B. Pan, a new species of Gesneriaceae from Guangxi and Guizhou in southwestern China, is described and illustrated. Although the leaf morphology of this new species looks similar to that of P. coriaceifolius (Y. G. Wei) Y. G. Wei & Mich. Möller and P. pseudocoriaceifolius Yan Liu & W. B. Xu, this remarkable new species can be easily distinguished from all other species of Petrocodon s.l. (the two above-mentioned species included) by the shape and color of its memorable corolla. Because of its restricted distribution and threatened environment, the current conservation status of this species should be assessed temporarily as “Endangered.”
