ILLUSTRATIONS. OF INDIAN BOTANY. 73 
placentas in the axis: valvate cestivation of the calyx : monadelphous stamens ; 2-celled anthers : 
and alternate stipulate leaves. All Indian plants having the above combination of characters, 
ought to find a place in one or other of the following sections. ‘Tiliaceew and Elawocarpee two 
very nearly allied orders are distinguished, the former by its distinct stamens, the latter by its 
lacerated petals. 
Tribe [—Helictereae. Flowers bisexual. Calyx irregular. Corolla irregular. Filaments 
either united into a tube longer than the ovary, or embracing the carpophore (pedicel of the 
fruit,) and free at the apex; anthers 2.celled, with an obsolete transverse septum. Ovary sessile 
or stipitate. Fruit with the carpels either distinct, or cohering, one or many seeded. Seeds 
albuminous. Leaves simple. : 
* * Eupilecteree Tube of the stamens elongated, embracing the stipe o! the ovary. Fila- 
ments free at the point, each bearing a single anther. —To this subsection our Helicteres isora 
(Isora corylifolia End.) belongs. 
fect or imperfect ovary. Fruit pod-shaped of several verticelled carpels, opening along the 
interior sature. Seed sometimes covered with an arillus, albuminous. Trees with simple or 
digitately compound Jeaves, with the petiol tumid at the apex. 
this section our genera Sferculia and Heritiera belong. The former, as left by Rox- 
burgh and DeCandolle, is completely broken down and now affords the types of no fewer than 
nine distinct genera, seven of which appertain to the Indian flora, the characters of these I 
shall add at the conclusion of this article. ; 
Tribe III— Bombacee. Flowers bisexual. Calyx 5-cleft, often irregularly divided, the 
cestivation then obscure. Corolla regular or none. Filaments united into a tube, covering the 
ovary. Anthers solitary or several cohering, cells indistinct or confluent, often anfractuose. 
Ovary sessile. Fruit capsular composed of cohering carpels. Seeds albuminous or exalbumi- 
nous, often enveloped in wool or even in pulp.—To this section the genera quoted under the 
former order belong. 
or convolute cotyledons. Trees, shrubs, or very rarely herbaceous plants. Leaves alternate, 
entire, or sometimes cut. Stipules twin Peduncles axillary, opposite to the leaves, and ter- 
minal, one or many flowered. 
0 this section the Cacoa tree, (Theobroma) and the bastard cedar tree (Guazuma) and 
several other Indian genera belong. 
confused genus, demanding a careful revision, as it certainly includes within itself the types of 
several. None of those referred to it from India are genuine species. Miedleia truncata | 
have removed to Ma/vacee, and of our three other species, which I think, should be reduced to 
one, Dr. Arnott has formed a new genus under the name of Lochennia,
