22 NEILGHERRY PLANTS. 
BURSINOPETALUM.—R. W. 
Flowers bisexual superior. Calyx 5-toothed. Petals five, furnished at the apex with an inflexe 
bidentate process, estivation valvate, Stamens 5, anthers Q-celled introrse. Ovary adherent, one-celled, 
with a single ovule pendulous from near the apex. Drupe ovoid umbilicate, one-celled, one-seeded, endocarp 
deeply inflexed so as nearly to divide the cell into two compartments. Embryo small, eccentric, immersed 
in the apex of ths fleshy albumen ; radical very long superior. 
A large umbrageous tree with very dark green, almost purplish foliage : leaves alternate, long petio- 
from two to three inches long by about one and half broad ; 
led, small in proportion to the tree, calyx conical, 
s five, ovate pointed, very coriaceous (whence

cordate ovate, obtuse two-celled introrse

glabrous coriacious. Flowers, terminal cymosely panic

alternate with the petals, filaments short compressed, anthers large, 
attached near the base. Ovary enclosed within the tube of the ca 
fleshy disk : style short : stigma obtuse. Fruit drupaceous, about t

small, eccentric, immersed near the apex of a copious fleshy albumen, the radicle, very long, in proportion to 
the cotyledons, pointing towards the hilum or apex of the seed. 
This genus differs from all the rest of the order in its peculiar seed, and from each by many charac- 
ters. It will form with Alph. DeCandolle’s genus, Hypocarpus, anew section of the order distinguished by 
their inferior ovary.

XV.—AURANTIACEX.— ORANGE TRIBE. 
This is a small but beautiful family of tropical evergreen trees and shrubs, found 
distributed in some of its forms all over the tropics. The two plants here represented are 
I believe the only species found on the more elevated portions of the Neilgherries. The 
Lime is found abundantly in what is called the Orange valley near Kottergherry, the Orange 
on the slopes at a lower elevation. The fruit of both is brought to Ootacamund and sold in 
the Bazars and both are considered by the natives quite indigenous. Such being the case 
I ought probably to have distinguished them as distinct species which, apparently, they are, in 
place of varieties of the same -species. The latter course having, however, been adopted 
in our Prodromus, I thought it better when putting names to the drawings, to leave 
the matter as there stated, rather than create discrepancies between the two works, 
the more so, as each variety is so distinguished that the name may be used either 
specifically or to indicate a well marked variety. Further consideration has since led me to 
take a different view, and I now think I should have designated the two plants figured as 
distinct species, under their respective names, Citrus vulgaris, and C. Limetta (by mistake 
Limonum on the plate which I request the reader kindly to correct). With ‘regard to the 
first, I still feel some doubt as to its being the true C. vulgaris, as the fruit and large leaves 
partakemore of the character of a citron than an orange ; but, on the other hand, the leaf stalk
