flowered species of the section and remarkable too for its

verse lines. Sheath striate, with small round or linear pust- 
ules each bearing a tuft of silky hairs. Inflorescences clus- 
tered scarlet red, on peduncles 1 cm. thick covered with dense

Negros, Cuernos mountains, Dumaguete, (Eimer 10365). 
In fertile glens at 4000 feet altitude. 
As a rule it is not advisable to describe a Hornstedtia 
without seeing the flowers, but an exception may be made 
in this curious species. The peculiar sheath and ligule as- 
well as the small flattened fruit is quite unique in the genus. - 
In some of the islands of the Eastern Archipelago, the — 
Sheath of the leaf is not only ribbed longitudinally but has 
transverse bars at interval, giving it a reticulated appearance.  . 
In this species the transverse bars are sometimes reduced to 
round pustules, bear tufts of silky hairs so that the sheath - 
appears spotted over with white tufts and these tufts run 
into transverse lines on the ligule.
