9. Chloracra. — Haemanthus dubius, Humb. et B. 
Kunth. 1. 281. Leaves oblong, lanceolate, sub- 
acute, smooth, above an inch wide, near five inches 
long ; scape round, spatlie many-leaved (I appre- 
hend including bractes); umbel 7 or more flower- 
ed ; peduncles 6-9 lines ; perianth red with green 
tips, pedunculous, 1£ inch long, tube-formed ; tube 
short ; segments conniving ; style straight, longer 
than the filaments ; stigma obtuse. Grows by the 
river Guallabamba, near Quito, in temperate 
mountainous situations. This plant, allied to bi- 
color, is remarkable by an unusual breadth of leaf ; 
which is a departure from the habits of the genus, 
perhaps the consequence of its inhabiting a richer 
and more humid soil. 
It will be observed that the genus Phycella has, as far as 
we know, red flowers ; that in the sandy and lower parts of 
Chili it seems disposed to have yellow at the lower part of 
the flower, in the higher regions of Peru green tips. I 
entertain no doubt of bicolor and chloracra belonging to this 
genus ; the latter has probably large bractes, which gave 
the notion of a many-valved spathe like Haemanthus, but I 
scarcely think it will be found to have many outer valves to 
the spatlie. There are frequently in scapaceous plants inner 
valves or larger outer bractes, of which it is difficult to say 
in which light they should be considered. I should how- 
ever by no means think a redundancy of valves to the spathe 
a sufficient cause for removing it from the genus. 
I find a decided difference of habit between Phycella, 
Habranthus, and Zephyranthes. Some years ago I planted 
three species of Phycella out of doors in front of a green- 
house, throwing a small heap of sawdust over them in 
winter. In that situation one of them flowered early in the 
summer, and they go to rest in the hot dry season. They 
are tempted by mild weather to push their leaf in the winter, 
in which case they suffer injury from severe frosts that may 
ensue, though they will endure a good deal ; and their habit 
is to flower after the leaf has acquired its growth before they 
go to rest. The Phycellas have been found difficult to cul- 
tivate, because they have been often set in peat, though they
