Pampas of Buenos Ayres, Dr. Gillies.—' The branches 
are covered with short rigid hairs, but many of them 
bear glands at their apex, and there being no other 
distinguishing character, we have united ours to the 
Brasilian plant.

1832, (N. 541.)—We have not seen cauline leaves: 
the floral leaves and calyces have a reddish tinge. 
The petals are white. There are from 20 to 30 fila- 
ments, or even more, but we have not observed that 
they are all antheriferous, although this is highly pro- 
bable, from the number of loose anthers lying in the ` 
cavity of the calyx. In this and the other species, the 
spinose teeth of the calyx are glabrous, while the’ mu- 
cronate teeth are of a dark colour, and singularly cris- 
tate, like the setze to the anthers of some Heaths. -
