6 NEILGHERRY PLANTS. 
MONOSIS. 
Capitulum one flowered. Achcenea glabrous terete. Pappus 2, 3 series, bristles rigid scabrous. 
Trees or shrubs :leaves alternate : panicles naked, the ends of the branchlets bearing subumbellate sessile capi- 
tula : scales of the involucrum imbricated, obtuse, shorter than the solitary flower : corolla rose coloured. 
This —_ was sagrese ttc in rine for the reception of the plant here represented and named with 
reference to the solitary m. Two additional species from Mexico were subsequently added, 
and a third is doubtfully chica to rhe genus by DeCandolle. 
Mexico the other from Brazil, found by Mr. Gardner. The latter mere nearly associates with the Indian 
species than the Mexican ones, being referable to the same section of the genus. 
Two more have since been added, one from 
The Neilgherry plant differs from the American ones in its arborous, habit, often attaining 40 or 50 
feet in height with a stem upwards of 2 feet in circumference. 
Coonoor and Kotergherry, and when in flower, as well as when the seed is approaching maturity, a very con- 
spicuous object owing to the large panicles which terminate each branch. The leaves are large, obovate, 
somewhat pointed, strongly transversely ribbid and of a course rigid texture not unlike those of the teak. 
It is abundant on the eastern slopes below 
The remarkable peculiarity of this genus, that of having only a single floret in the involucrum, is so far as 
T am aware only met with in two or three other genera in the order ( Shawia) being one : that also is referable 
to the same tribe along with another having only two. Many genera have few flowered capitula, but there are 
very few examples where syngenesious plants lose their aggregate character by having single flowered capitula 
with many scaled involucra.

TRIBE III ASTEROIDE#. 
This is a large tribe including, according to DeCandolle upwards of 170 genera, 
thirty-one of which have representatives in the Indian Flora. America however is the head 
quarters of the tribe. There the genus aster is found in all its glory and contributes largely 
to ornament the flower borders of European gardens. The tribe is distinguished by having 
the Capitula, usually, heterogamous, namely, female florets in the ray and bisexual ones in 
the disk ; sometimes they are homogamous, that is, having all the florets uniformly bisexsual, 
or monoicous and occasionally they are dioicous, all males on one plant and all females on 
another. The Styles of the hermaphrodite flowers are cylindrical above and bifid with 
_ longish linear somewhat flattened, often subacuminate, rarely obtuse branches ; externally 
minutely perberulous. The Stigmatic lines of glands are slightly prominent, extending to 
the origin of the external pubescence. The Corolla pellucid, staminigerous, tubular, regu- 
larly dentate. The pollen globose echinulate. From these characters it would appear . 
that the tribe, if really a natural one, presents considerable diversity of form and structure 
of the flowers, but all bound together by the uniformity of character presented by the style 
and stigmas. In the subdivision considerable importance is attached to the colour of the 
flowers, namely, whether homochromous, the disk and ray of the same colour or heteroch-
