8F4A87E3637D442EFF5FA35C5352EC45.taxon	etymology	Etymology and vernacular name: — The specific epithet refers to Cerro Morroco, one of the locations where the species was found. Morroco is also the name given to the local indigenous community. In the Barasano indigenous language, Lacistema morrocoensis is known as Cumuᵾ (Cárdenas-López et al. 2019).	en	Puerta, Jorge Mario Vélez, Marinho, Lucas Cardoso (2025): Lacistema morrocoensis, a new Colombian species of Lacistemataceae, and the extension of L. macbridei distribution to the country.

8F4A87E3637D442EFF5FA35C5352EC45.taxon	distribution	Distribution and preliminary conservation status: — Lacistema morrocoensis is known from two localities in rocky outcrops (Fig. 3 D-E) of the Guiana Shield in the departments of Amazonas and Vaupés, Colombia, between 100 – 550 meters above sea level, growing in shrub formations and surrounding forests (Fig. 4). The preliminary conservation status of L. morrocoensis is here assessed as Critically Endangered (CR) based on an extent of occurrence less than 88 km 2 and an area of occupancy minor than 8 km 2 [B 1 + B 2 bi, ii, iv] (IUCN 2012). Taxonomic notes: — Lacistema morrocoensis belongs to the L. sect. Lacistema (“ Eulacistema ” in Chirtoiu 1918: 329), with a very short or practically no style and sessile or nearly sessile stigmas. The species can be recognized by the combination of small, coriaceous and glabrous leaves with convex to rounded apex, black dots on the adaxial surface, and 3 – 5 pairs of secondary veins, inflorescence 1, rarely 3, spikes per axil, flowers with stamens and gynoecium glabrous and stigmas very short. Lacistema morrocoensis had been identified in the herbaria as Lacistema aggregatum, a widely distributed species of the family which belongs to the same section. The species can be distinguished from L. aggregatum by the small (≤ 8.3 × 3.3 cm) and coriaceous leaves (vs. ≥ 8.5 × 3.5 cm and chartaceous) with convex to rounded apex (vs. acute or apiculate apex), 3 – 5 pairs of secondary veins (vs. 5 – 6) and 1, rarely 3, spikes per axil (vs. 2 – 8 per axil).	en	Puerta, Jorge Mario Vélez, Marinho, Lucas Cardoso (2025): Lacistema morrocoensis, a new Colombian species of Lacistemataceae, and the extension of L. macbridei distribution to the country.
