VELLOZIACEAE 
VELLOZIA GLAUCA Pohl Ic. et Descr. Pl. Brasil. 1: 125, ¢. 200. 
VaR. GENUINA Seubert, in Mart. Fl. Brasil. 31: 79, pro parte 
quoad synonym, z. e., = V. glauca Pohl sensu stricto. 
Brasilia, Goyaz, dry campos, terra de natividade ( Gardner II, 
1840, 20. gor8), in Herb. N. Y. Bot. Gard. and Kew. 
At first we believed this plant to be a new species, because it has 
simple conical acuminate scales on the ovary, while all specimens 
seen in various herbariums and named V. glauca genuina have 
furcate or fimbriate scales. After examining carefully the original 
plate and description, one will be convinced that the plant with sim- 
ple scales is the true V. glauca, the others being only varieties, 
races, or allied species of it. Very likely the plant with furcate 
scales has been considered as the typical variety on account of the 
description of Seubert in Flora Brasil. /ec. cZt. He says ** capsulae 
tuberculis apice vix truncatis sed excurrentibus in cuspides binas vel 
unicam hamoso-recurvatam .. .;” but considering the plate of the 
type, Pohl writes authoritatively : ‘‘ squamae opacae, conico-acutae.” 
The scales of Gardner no. gorés are constantly simple, conical, acute 
and even acuminate; therefore we believe that it is the true lV’. 
gtauca of Pohl, and that Seubert confused the two varieties.
