Bourbon plant, which has no stinging bristles. Native name 
* Amiana," common probably to this and the other stinging 
tree nettles of the island. 
OBETIA PINNATIFIDA, n. sp. 
O. ramulis crassis, foliis magnis cordato-orbicularibus irregulariter cre- 
natis profunde pinnatifidis segmentis lobatis facie scabris dorso albido-ve- 
lutinis, paniculis laxis rhachibus setosis, perianthii foeminei segmentis orbi- 
cularibus valde accrescentibus. 
A tree, with a habit just like that of O. morifolia, the branch- 
lets as thick as a man’s little finger, the leaves crowded at the top, 
with large persistent ovate dark brown scariose stipules. Petioles 
3-4 in. long, densely armed with deflexed pellucid stinging 
bristles. Leaves sometimes above a foot broad and nearly as 
long, deeply cordate at the base, deeply pinnatitid, and the 
primary segments again deeply lobed, the marginal crenations 
large aud coarse, the upper surface dark green and very rough, 
the lower matted just as in O. morifolia with thin whitish velvety 
tomentum. Panicles very compound, half a foot or more long, 
the slender rhachises and short peduncles sparsely armed with 
deflexed stinging bristles. Flowers in dense spaced clusters. 
Female perianth of 4 orbicular accrescent greenish-brown seg- 
ments jin. broad. Fruit ovoid, lenticular, greenish, } lin. long 
and broad.—Central Madagascar, Baron 1729! 1822! 
OBETIA LACINIATA, n. 8p. 
O. ramulis crassis, foliis profunde bipinnatifidis segmentis angustis pro- 
funde crenatis facie scabris dorso dense breviter pilosis, paniculis laxis 
rhachibus setis pellucidis densis armatis, perianthii masculi globosi seg- 
mentis 5 oblongis. 
A tree, with exactly the habit of the two other species. 
Stipules ovate, scariose, persistent, cuspidate, 4 in. long.  Petioles 
about 2 in. long, densely grey-puberulent and densely armed with 
pellucid stinging bristles. Leaves 5-6 in. long and broad, cut 
down to a short distance from the midrib and the segments again 
deeply pinnatifid, acuminate, coarsely serrated, the upper surface 
dark dull green and scabrous with short bristly hairs, the lower 
densely pilose, the midrib of the segments densely armed with 
stinging bristles. Panicle oblong-deltoid, decompound, half a 
foot long, the slender rhachises densely armed with bristles. Male 
perianth orbicular, j in. in diam., with 5 oblong greenish seg-
