males, and with four ovaria: the situation of the pla- 
cental suture, which is anticous, is however an in- 
superable objection. "The ovarium is never straight, 
nor is the incurvation of its apex gradual, but almost 
sudden. The spurious dessespement is a mere increase 
of growth of the placenta or rather of the part sustain- 
ing it, and it consequently does not consist of two 
plates. It is not a true drupe, since it is the testa 
which has become osseous, as is evident from the pre- 
sence of the micropyle on it. In addition to which I 
have traced its development. The albumen is copi- 
ous, and the radicle superior. The cotyledons are 
incumbent or rather they are opposite the narrow and 
true faces of the seed. The testa at a very early period 
(but after fecundation) has contracted an adhesion 
with the pericarp. 
Dipterocarpee—The saul, Shorea robusta, a gigantic 
Dipterocarpus exists in Upper Assam, lat. 28 N. Two 
species are found at Moulmein lat. 17 N. besides many 
other species representatives of other generi of this 
family. 
Hamamelacee.—Fothergilla has the dix truncate 
irregularly toothed. The filaments do not seem to be 
a multiple of the floral envelopes. They vary in num- 
ber from 18 to 23 or 24. The anthers are quadran- 
gular, not turned inwards and open longitudinally. The | 
cells of the endothecum are ovate or globose, and. the 
fibres well marked. In one case T found 2- filaments :
