T y pe from Peru, ad flum. 
Pampayaco, leg. Porppic. A fi- 
gure of the type-specimen (by 
METTENIUS) is to be found in (B), 
and with it agrees perfectly the 
type-specimens of L. Poeppigiana 
Pr. (hb. PnESL!), which also was 
collected by Porpric “in Cuba"; 
there is no doubt that PnEsr's 
specimen is of the type-collection, 
and the locality erroneous; PoEP- 
pic collected in 1829 both in 
Peru and in Cuba. 
D. semihastata | resembles 
much a small form of D. macro- 
lis, and together with that spe- 
cies its position within the genus 
is doubtful. It lacks, namely, stel- 
late hairs, and it is possible that 
the two species are less cut mem- 
bers of the group of D. patens; 
still in general aspect they re- 
semble other species of the pre- 
sent group in which I place them. 
The accompanying figure will 
give an idea of D. semihastata ; 
in pubescence, auricled, subentire 
pinne, of which the lower ones 
are reflexed, and also in venation 
it agrees with D. macrotis, but it 
is much smaller and with only 
2—3 pairs of veins, and the au- 
ricles are much shorter.
