First Time

A new taxonomic revision of Capirona (Rubiaceae, Condamineeae) is presented. Delprete (1999) treated Condaminea macrophylla as a new synonym of Capirona decorticans; as the former name has priority over the latter, the new combination Capirona macrophylla is here proposed. Full synonymy, type citations, further notes on lectotypification of C. decorticans, and an amplified description of the single species recognized in the genus are provided. Additional type specimens (i.e., not mentioned in previous revisions) and barcodes or accession numbers for all type specimens are here cited for the first time. A preliminary conservation assessment is proposed using the IUCN Red List Categories and Criteria.

Miconia rheophytica is described, illustrated, and compared with presumed relatives in the Octopleura clade. It is distinguished by its narrowly elliptic to ovate-lanceolate leaf blades with entire to subentire margins that have evenly spaced spreading smooth eglandular trichomes 0.8−1.4 mm long, an indumentum of dendritic trichomes with short axes and terete radiating arms on distal internodes, adaxial petiole surfaces, and primary and secondary veins on abaxial leaf surfaces, unribbed hypanthia that are constricted and tapered distally below the torus and covered with a mixture of basally roughened trichomes and dendritic trichomes with short axes, anthers with two ± truncate apical pores, eglandular anther appendages, 3-locular ovary, and berries that are bright blue at maturity. It is known only from flash-flooded riverbanks in three river canyons in the Magdalena Medio region of Antioquia, Colombia. A conservation assessment of “Endangered” is recommended for this species based on IUCN Red List Categories and Criteria.

Ocimum sebrabergensis, here described as new species, has a restricted range and is only known from the Zebra Mountains within the Kaokoveld Centre of Endemism, northwestern Namibia. These shrubs grow on clayey soil among greyish black rocks of anorthosite. Diagnostic characters for O. sebrabergensis include the mauve-coloured corolla with four orbicular lobes on the posterior lip and the calyx which has the lateral lobes of the anterior lip asymmetric lanceolate. Ocimum sebrabergensis is placed in Ocimum subg. Ocimum sect. Hiantia subsect. Hiantia ser. Serpyllifolium. A comparison of some of the more prominent morphological features to differentiate between O. sebrabergensis and its possible nearest relatives, O. burchellianum and O. fimbriatum, are provided. Based on IUCN Red List categories and criteria, a conservation assessment of Vulnerable (VU D1) is recommended for the new species.

Spiradicliskarstana, a new species of Spiradiclis (Rubiaceae) collected from Yunnan, China, is described for the first time. It is morphologically close to S.jingxiensis, but differs from the latter mainly by its inflorescences with 5–9 flowers, its 1.5–2.4 mm long peduncles, its stipules shorter than 1 mm and the 5–12 pairs of secondary veins. The conservation status is assessed as “Vulnerable” (VU) according to the IUCN Red List Categories and Criteria.

Dracaena cambodiana Pierre ex Gagnep., a dragon tree species, is reported here for the first time from India. Its taxonomic relationships with other closely related species of genus Dracaena Vand. ex L. are examined and discussed. A detailed taxonomic description, along with color photographs is provided to facilitate its future identification. Recent surveys confirm that the habitat and regional population of the plant is under severe threat. Hence, following IUCN Red List Categories and Criteria, it is regionally categorized as Critically Endangered.

Gravesia serratifolia, a new species from upper elevations of Marojejy National Park in northeastern Madagascar, is herein described, illustrated, mapped, and compared with similar species. It is readily characterized by its sparingly branched habit, leaf blades coarsely serrate with a moderate to sparse lepidote indumentum on both surfaces, inflorescence of few-flowered dichasia, calyx obsolete or evident as depressed truncate undulations with prominent calyx teeth that are laterally compressed when fresh, filaments with rusty-brown glandlike indumentum, and dorso-basal staminal appendages linear-oblong and widely spreading to coiled. A conservation assessment of Vulnerable is recommended for this species based on IUCN Red List Categories and Criteria.

Syzygium kuneneense, here described as a new species, is known only from the northern part of the Namib Desert in the Kaokoveld Centre of Endemism, southwestern Angola and adjacent northwestern Namibia. These rheophytic shrubs or small trees grow among rocks on the floodplain and banks of the lower Kunene River on the international boundary between Angola and Namibia. Diagnostic characters for Syzygium kuneneense include the oblanceolate or narrowly elliptic leaves, dense flower heads and the pedicellate flowers. A comparison of some of the more prominent morphological features to differentiate between S. kuneneense and the morphologically most similar species, S. guineense, is provided. Based on IUCN Red List categories and criteria, a conservation assessment of Vulnerable (VU D1) is recommended for the new species.

Petalidium kaokoense, here described as a new species, is only known from the Hartmann Mountains and one other location on the inland plateau in the Kaokoveld Centre of Endemism, northwestern Namibia, where it grows on hillsides and mountain slopes. Diagnostic characters for P. kaokoense include the stout trunk on older plants, white bark, peeling on the younger branches in long, narrow strips, stellate trichomes, short inflorescences of racemoid dichasia with acute linear-oblanceolate or linear-lanceolate bracts, flowers with maroon corollas with the two upper lobes connate towards the base and the lower lobe with two yellow spots near the base. A comparison of some of the more prominent morphological features to differentiate between Petalidium kaokoense and its presumed close relative, the morphologically similar P. physaloides, is provided. Based on IUCN Red List categories and criteria, a conservation assessment of Vulnerable (VU D1) is recommended for the new species.

Blakea echinata from the lowland Caribbean rainforest of Panama is described, illustrated, mapped, and compared with superficially similar species. It is readily distinguished by its elongate internodes; indumentum of spreading smooth (sometimes gland-tipped) trichomes on distal branchlets, leaves, floral bracts, and calyx lobes intermixed with laterally compressed and somewhat roughened conic to clavate or ± triangular trichomes on distal branchlets, floral peduncles, and abaxial surfaces of floral bracts; rhombic reflexed basally clawed petals; yellow-orange unappendaged anthers; and ovary apex that is elaborated into a distally glandular-laciniate collar 5–6 mm long that envelops the style base. A conservation assessment of Critically Endangered is recommended for this species based on IUCN Red List Categories and Criteria.
