species. 
Baccharis aphylla, var. Boliviensis. Sch. Bip. Bull. Soc. Bot. Fr. 
xii. 81. Yungas, 1890 (620). Staminate plant only. — Rusby 
1567. 
Baccharis trimera, D. C. Prod. v. 425. Yungas, 1890 (692). = 
Rusby 1564. We have in the herbarium excellent fruiting 
specimens of В. gemistilloides, Pers., of the Wilkes’ Exploring 
Expedition from Peru, exactly equalling Matthew’s 193 from 
Peru; but they are very distinct from Mr. Bang’s specimens, 
which are identical with Mandon’s 203 and Rusby’s 1564. It, 
therefore, seems to me that В. trímera is distinct from В. genis- 
tilloides, Pers. 
BACCHARIS MICROPHYLLA, var. (?) PULVERULENTA, n. var. Pale yel- 
lowish, the branchlets and leaves rusty-scurfy, the latter 
strongly revolute and beset underneath with large black 
glands.
