Capsule totally brown when mature, 5.7–6.4 × 7.6–8.7 mm, subspherical to cupuliform; pedicel 15.6–25.9 mm long. Seeds not seen.</p><p>Distribution, ecology and phenology:— Allomaieta melidae is known only from type locality at Central cordillera of the Colombian Andes, at about 1400 m elevation (Figure 5.). It grows in the understory of dense montane forests. This species has been collected with flowers, flower buds and fruits in July.</p><p>Conservation status: — Allomaieta melidae is known only from type locality. The single population grows in an unprotected area with constant loss of forest cover for livestock. Consequently, its area of occupancy (AOO) can be estimated at only 4 km ². This species might be threatened, based on its reduced range and habitat restricted to ombrophilous environments. Based on the current knowledge about this species, we suggest the provisional category “Critically Endangered” (CR) B2ab(ii,iii,v), following the IUCN guidelines and criteria (IUCN 2024).</p><p>Etymology:—The epithet honors the memory of the agronomist Melida Restrepo de Fraume (1935–2010), who was a pioneer botanist in the department of Caldas; she was the director of the Herbario de la Universidad de Caldas (FAUC) between 1974 and 1990 and was always willing to share her knowledge about Andean ecosystems, the establishment of more environmentally friendly production systems, and the use of promising plants from a scientific perspective and for the development of communities.</p><p>Notes:— Allomaieta melidae resembles A. strigosa (Gleason, 1933: 36) Lozano in Lozano &amp; Becerra-de-Lozano (1999: 11) by the strigose indument and markedly suprabasal leaves. However, the smaller flowers of A. melidae have light pink petals with violet stripes and white margin, whereas A. strigosa has bigger petals color reddish-purple with violet stripes. Additionally, the branches and petiole trichomes are larger for the last species. Other diagnostic traits are listed in Table 2.</p><p>Allomaieta melidae grows sympatrically with A. peltata (described below), but the latter has peltate leaves, different inflorescences and flowers at anthesis with white petals with hyaline longitudinal lines and light pink margin (Table 1).</p><p>Among the species of Allomaieta with a strigose indumentum, A. melidae shares morphological similarities with A. javierbarrigae Mendoza-Cifuentes (2018: 11), but differs in having 3-suprabasal venation, inflorescences arranged in simple cymes with 3–5 flowers, and floral buds that are subglobose to prolate with an apiculate apex (vs. 3-basal leaves, dichasial cymes with monochasial paracladia bearing two flowers, for a total of 7 flowers, and fusiform floral buds in A. javierbarrigae). Additionally, these species are separated by the Magdalena Valley of Colombia, a major geographic barrier (Table 1).</p></div>	https://treatment.plazi.org/id/3D5387AA663BFFD7FF76605C4236FEC9	Public Domain	No known copyright restrictions apply.

Seeds 0.6–0.8 x 0.3–0.4 mm, cuneiform, raphal zone apically extended, and testa papillose.</p><p>Distribution, ecology and phenology:— Allomaieta peltata is known only from the Central Cordillera of the Colombian Andes, occurring at elevations between 1350 and 1700 m (Figure 5.). It grows in the understory of dense montane forests. This species has been collected with flowers, flower buds, and fruits in February, March, and July. The flowers have a sweet smell and are visited by Curculionidae beetles.</p><p>Conservation status: — Allomaieta peltata is known only from two locations: one population grows in an unprotected area experiencing continuous forest cover loss due to livestock activities, while the other population is located within the protected area of Selva de Florencia National Natural Park. According to the current collections and known populations, this taxon has an EOO of 9.3 km ² and an AOO of 12 km ². This species is considered at risk due to its narrow distribution and its specialized and threatened habitat. Based on current knowledge, we propose assigning the provisional category ‘Endangered’ (EN) B1a+B2a(ii,iii,v), as most occurrences are recorded outside protected areas where vegetation cover is consistently declining (IUCN 2024).</p><p>Etymology:—The epithet refers to the peltate leaves, a unique trait of this species within Allomaieta .</p><p>Additional specimen examined (paratypes):— COLOMBIA.

Castaño 1128 (FAUC!) .</p><p>Notes:— Allomaieta peltata resembles A. strigosa and A. melidae by the strigose indument, but A. peltata is the only known species within Allomaieta that has peltate leaves (vs marginal petioles in the remaining species of Allomaieta), white flowers (vs heliotrope in A. strigosa and light pink in A. melidae). Additionally, A. peltata has leaf blades with usually cuspidate apex, inflorescences more branched and different size petals. Comparison between species with strigose indument are provided in Table 1.</p><p>In Allomaieta, the petals may be white or, more commonly, bicolored to varying degrees, typically with a purple to pink outer region and a yellow or white center, sometimes with a gradual transition of color toward the middle (Michelangeli et al. 2011, Michelangeli et al. 2022). Of the 13 known species of Allomaieta, only A. ebejicosana Lozano in Lozano &amp; Becerra-de-Lozano (1999: 17), A. peltata, and A. zenufanasana Lozano in Lozano &amp; Becerra-de-Lozano (1999: 12) have petals that are entirely or almost entirely white. In addition to its peltate leaves, A. peltata is characterized by a strigose indumentum on branches, petioles, inflorescences, and floral buds (vs. hispid trichomes in A. ebejicosana and A. zenufanasana). Finally, A. peltata is not sympatric with the other white-flowered species of Allomaieta (Lozano &amp; Becerra-de-Lozano 1999, Mendoza-Cifuentes 2018, Murillo-Serna &amp; David-Higuita 2021, Murillo-Serna et al. 2025).</p></div>	https://treatment.plazi.org/id/3D5387AA663FFFD2FF7663F74191F8DC	Public Domain	No known copyright restrictions apply.
