apparently constant character, the form of the filaments of the lower 
ina, which, arising from the mouth of the tube, are always 
either bifid at the base, or furnished with a tooth or angle, and from 
which are their anthers, adhering to each other. This character 
0 assigned to Torenia; and Tittmannia was separated by 
Reichenbach, to include those species which have a short calyx not 
nave that name for it. Artanema, with a peculiar habit 
(that of Sesamum), is distinguished as well by the form of the co+ 
rolla as by the presence of squame: in the tube of the corolla, ana~ 
logous to those of Hydrophylleze, Labiate, &c. which I have not ob- 
served in any other Scrophularineous genus. It was mistaken by 
Persoon for Loureiro’s Diceros, which, from his description, appears 
to me to be something very different, although I can form no guess 
ellie. The American ones are distinguished from Bonnaya by the 
bifid filaments, and from Vandellia by the lower stamina being sterile.

Heteranthia, distinguished, according to Nees and Martius, by 
the singular disparity of the anthers, is unknown to me, as also 
Mecardonia of Martius, which, according to his description of the 
is allied to Matourea, by the imbricate many-leay Irregular calyx. 
Conobea of Aublet has precisely the habit of some of the Ameri- 
can Herpestides, but with a regular calyx. Not having an opportu- 
nity of examining the flowers and capsule in the only specimens I 
have seen (in the Banksian herbarium), I am unable to determine 
the precise situation of the genus,
