258 Botany of Illinois and Missouri. 
DIANDRIA. MONOGYNIA. 
Ligustrum vulgare Lin. 
Oss. This shrub attains the height of seven or eight feet, 
on the prairies, near St. Louis. It 1s doubtful whether it is e 
native. Dr. Torrey, in his Flora of the Northern and Mid- 
dle States, says that it is introduced from Europe ; but its 
situation near St. Louis, appears to be such as to lead to a 
contrary opinion. It flowers early in May. 
Veronica peregrina Lin. t 
Has. On the banks of creeks, near St. Louis—common. 
It flowers in May. 
Leptandra virginica Nut. 
Has. Prairies near St. Louis—rare. June. 
Gratiola missouriana.* 
Root fibrous, perennial. Stem erect, simple or sparingly 
branched, terete, from 4 to-6 inches high. Leaves narrow- 
lanceolate, connate at base, toothed near the apex, opposite. 
Peduncles alternate, rarely opposite, longer than the leaves. 
Bracts longer than the calyx. Segments of the calyx 
linear-lanceolate, unequal, more than half the length of the 
tube of the corolla. Corolla yellow; tube slightly curved. 
Filaments two, of the length of the tube. Capsule ovate, 
acute, shorter than the onl Whole plant viscid-pubes- 
cent. 
Oss. This plant differs from G. virginica L. in the follow- 
ing particulars—viz. Its habit is more slender—leaves nar- 
rower, and but sparingly toothed at the summit—calyx 
leaves and peduncles longer—capsule smaller and more 
acute. 
Has. On the alluvion of the Mississippi river, near St. 
Louis. June. 
Lindernia dilatata Muh J.

+ Ihave, with few exceptions, omitted synonyms, as these may be 
found in the works of Parsh, Torrey, and others.
