Two other ver orders, the Acanthacez and Verbenacee, 
occasionally come also very near ‘to Scrophularinez, although the 
are in general sufficiently removed to have occasioned but little diffi- 
eulty in their separation. Some connecting genera call, however, 
for a few observations in the case of each. 
Acanthaceee (of which the Indian species and the general cha- 
racter of the order are bly elucidated by Nees v. Esenbeck, 
in Dr. Wallich’s Pl. As. Rar "3, 70.) are generally known by the im- 
bricate polysepalous calyx, the elastically dehiscent capsule, the retina- 
cula of the dissepiment, the want of albumen, and the peculiar habit 
derived chiefly from the inflorescence. The first of these characters is 
common to many Gratiolee ;+ the second is observable in Buchnera, 
the retin are wanting in some genera of Acanthacea, and the 
indehiscent, and an ovarium divided into uniovulated cells. The 
first of these characters occurs in Thylacantha, Teedia, Leucocarpus, 
and Tozzia, the second in se ag but in neithvee: of these cases 
are both combined. calyx, corolla, and genitalia are the same 
in Seay ead and i oie In the latter setts a seeds 
are to have occasionally a small quantity of a 
indehiscent fruit, with monospermous cells, besides some peculiarities 
in the structure of their anthers. 
entibulariee, a small order, consisting of Pinguic ula and 
same calyx, corolla, stamina, bivalved capsule, and albuminous seeds, 
but distinguished solely by, their really unilocular fruit, vee a free 
central placenta, and the minuteness of their embryo. In ct of
