THE EOSY AIE-PLANT. 
sism 
The sepals and petals are remark- 
Tlie lip is more or less tootliletted, not unfrequently even tliree-lobed, 
anci partially imitating the bluntness of the sepals. The ovary is much shorter than the %— not 
blunt — almost 
stiff 
These 
differences render it impossible to regard the two plants as mere forms of each other. 
Another plant closely allied to these is the Aerides maculosum, figured in the Botanical Begister 
for 1845, t. 58. This differs in having flowers loosely arranged, larger, more spotted, and generally 
somewhat panicled. The lip has, moreover, at its base two small flat spreading acute lobes ; the same 
lobes occur, no doubt, in A. affiiie and roseum, but they are smaller, erect, and rounded. 
Finally, Dr. TVright has lately pubhshed an Aerides Undleyanum, with short leaves, short erect 
racemes, flowers far larger than in the allied species, and a very distinctly serrated plaited hp. Of 
foUowin 
(( 
deeply 
erect, many-flowered ; sepals and petals obovato-suborbicular, anterior sepals somewhat larger, and, 
like the lip, thick and coriaceous ; lip three-lobed, attached to the point of the prolonged base of 
the column ; lateral lobes small, ovate, middle one large, ovate, ventricose above, crisp on the 
margins, with a large fleshy lobe at the base, closing the spur ; spur short, rigid, inflexed under the 
lamina; capsules large, obovate, long pedicelled; flowers pinkish-lilac, deeper on the axis, fining off 
to nearly white on tlie margins; lip the same, but much deeper coloured. On the clefts of rocks, 
bordering the Kartairy Falls, below Kaitie ; also on rocky clefts on a high hill over Coonoor, 
flowering nearly the whole year ; at least I gathered it in April, and 1 have it now (November) in 
flower in pots in Coimbatore.'' 
In order to put these distinctions in a clearer light, wc propose the following short technical 
characters. The species constitute a weU-marked division of the genus Aerides, from which many 
of those now on record will have to be excluded whenever the genus is revised :
