Figure 1

Trees and shrubs 1.5–23 m tall; branches with puberulous indumentum. Leaves 1–3 pairs of pinnae; petiole 1–5.5 cm, glabrous to puberulent; nectaries at the tip of the leaflet stalk and smaller ones between all but the first leaflet pair, pateliform; leaflets 3–6 pairs, 3.5–16 × 2–6 cm, oblong to ovate, apex acute to acuminate, rare caudate, base cuneate to rounded, margin plane, concolor, glabrous to minutely puberulent along the central vein of the adaxial surface only, venation brochidodromous. Inflorescence spiciform, peduncle 2–6.5 cm, floral axis 4.5–16 cm, both puberulent. Flowers white or greenish, puberulent, sessile; calyx tubular, 0.1–0.25 cm, corolla tubular, 0.5–0.7 cm; filaments of the staminal tube white; ovary glabrous ca. 0.1 cm. Pods linear to recurved. Seeds unseen.

Distribution and habitat: — Punjuba killipii occurs along the Andean montane and premontane forests, and moist secondary woods, in Colombia, Ecuador and Peru, between 1400 and 2500 m elevation. This species presents the largest continuous geographic distribution within the genus, from the north of Peru, up to the Andean valeys of Antioquia, in Colombia ( Fig. 1 ).

Phenology: —Flowering from January to April, and July to December; fruiting from February, March, and August.

Notes: — Punjuba killipii is morphologically similar to P. lehmannii by the leaves with 1–3 pairs of pinnae, and the spiciform inflorescence, but differs by the leaflets 3-6 per pinnae, concolor, with plain margin (vs. leaflets 5-7 per pinnae, discolour, with revolute margin in P. lehmannii ).

Conservation status: —The species presents an Extent of Occurrence (EOO) of 373,696.868 km ², and an Area of Occupancy (AOO) of 88 km ². The species was assessed as Least Concern (LC) by Lopez-Gallego & Morales (2023). Here, we confirm the assession as Least Concern (LC), according to the IUCN Red List categories and criteria (2022). The assession as LC was mainly by the range of distribution and the occurrence of Punjuba killipii in different protected areas in Colombia and Equador. However, we highlight the ecosystem conversion, agriculture, residential and commercial development as threats to the species ( Lopez-Gallego & Morales 2023). Thus, we reinforce the need for further studies on the distribution, ecology and conservation actions for the species.
