centrale breviore quam lateralia. Fructus quam tubi calycini 
aequantes vel leviter longiores. Semina matura non adsunt. 
Piliferous herbs about 10-20 cm alt., with the basal parts ligni- 
fied. Vegetative internodes 1.2-5.5 cm long. Hairs mostly 
branched with rigid and rugose cell walls, a few glanduliferous in 
calyces and stems (the head unicellular or pluricellular, but the 
stalk always unicellular). Leaves petiolate exclusively cauline: 
blades elliptic 1.5-3.5 cm long, 0.3-1 cm wide. Cymes contracted 
with very short internodes. Flowers sessile or subsessile. Calyx 
3.5-4 mm long, with 5 more or less equal lobes. Corolla 9-15 mm 
long. Stamens 2; staminodes 3, the central one shorter than the 2 
laterals. Disc red. Capsule as long as the calyx tube or slightly 
longer. Mature seeds not seen.

“Fl. amar.-verd.” Holotyvypus (USM). 
Obs.— Together with 1. Darcyvana, this species differs from L. 
fomana and L. acutiloba in the basally lignified stems, and by not 
having leaves disposed in rosettes. As indicated in the key, L. 
Ferrevraei is distinguished from L. Darcvana mainly by the char- 
actertistics of the pubescence, the petiolate leaves with elliptic 
blades, the contracted cymes with sessile or subsessile flowers. 
and the longer vegetative internodes. 
In honor of Dr. Ramon Ferreyra of Lima, who collected the 
holotype specimen. His name is latinized as Ferreyraeus.
