401. OVOSTIMA Raf. Cal. campanul. 5 
fid, segments unequal leafy entire. Corolla 
tubular ventricose smooth limb large spread- 
ing with 5 lobes subequal rounded. Stamens 
4 didyn. included, filaments subequal smooth ; 
anthers obtuse base sagittate bifid bicuspidate 
21ocul. openinglateraly, sutures pubescent. Style 
elongate strait, stigma capitate ovatoblong 
acute nodding. Capsule small inclosed. Pe- 
rennial ? leaves opposite petiolate , flowers 
axillary white — a singular Genus partaking of 
the characters of many akin, but distinct by 
calix, stigma and white flowers as in Pagesia. 
The name means ovate stigma.

stem simple terete purplish, leaves opp. petio- 
late oblong lanceolate both ends acute, lower 
repand or with remote unequal obtuse teeth, up- 
per subentire, flowers subsessile, segments of ca- 
lix ovatoblong — Florida or Alabama, received 
without name with many other rare plants. I 
first called it Aureolaria pallida, but have been 
able to ascertain it since as a N. G. near Pa- 
gesia ; I have not the ripe fruit however. Stem 
sesquipedal, leaves thin pale beneath 2 or 3 
inches long, flowers large nearly 2 inches long, 
segments of calix longer than camp, base, co- 
rolla thin apparently white or very pale ochro- 
leucous.

didyn. inclosed. Capsule a cum. subuniloc? 
valves indexed. Leaves oppos. peduncles ax- 
illary flowers red or scarlet — this fine tropi- 
cal Genus must be added to our Flora. Gal-
