2D07D4EFB0C2528ABDF3E17569FD933B.taxon	diagnosis	Diagnosis Faramea humicapiens is similar to F. tinguana in being erect, monocaulous, woody plants up to 1 m tall, with large, sessile or subsessile leaves in apical rosettes, gathering leaf litter at their bases, and short, axillary, 1 – 3 - flowered inflorescences. The former differs from the latter in having sessile or subsessile inflorescences with 1, 2, or 3 flowers (vs pedunculate, with peduncles 6 – 8 mm long, cymose, commonly 3 - flowered in F. tinguana), bracteoles subtending the hypanthia lanceolate to narrowly lanceolate, 6 – 12 × 0.7 – 3 mm, with entire margin, acute to acuminate at apex (vs subtending the pedicels, narrowly ovate to oblong, 2.5 – 3.5 × 0.7 – 1.5 mm, with fringed margins, often with 2 – 3 apical lobes 0.3 – 0.5 mm long), flowers sessile to subsessile, with pedicels (when present) to 1.5 mm long (vs with pedicels 2 – 4.5 mm long), calyces 1.3 – 1.5 mm long (vs 2.8 – 3 mm long), corollas 17 – 20.5 mm long, with tubes 12.5 – 14 mm long and lobes 3.5 – 6.5 × 1.5 – 1.8 mm (vs 27 – 29.5 mm long, with tubes 16 – 17 mm long and lobes 11 – 12.5 × 3.5 – 4 mm), and anthers 2.5 mm long (vs 4.5 mm long).	en	Delprete, Piero G., Jardim, Jomar G.

2D07D4EFB0C2528ABDF3E17569FD933B.taxon	etymology	Etymology The specific epithet is derived from the Latin words “ humus- ” (“ ground ”) and “ - capiens ”. In this sense, “ capiens ” is the present participle of the transitive verb “ capere ” (capio, capis, cepi, captum), which means “ to hold ”. Hence, the specific epithet means “ holding humus ”, referring to the ability of this plant to accumulate organic material at the leaf bases.	en	Delprete, Piero G., Jardim, Jomar G.
