song to the Genus, the L. latifoKum forms my 
G. Cyphorima 1819 having 5 pits outside of 
the mouth of corolla, with 5 corresponding knobs 
inside. 
767.. Batjschia albxflora Raf. annual, glau- 
cous, hairs all over white adpressed, stem sim- 
ple, leaves petiolate ovate acute, flowers few 
terminal, tube of corolla equal to calix. limb 
campanulate large plicate hardly lobed. — On 
the River Arkanzas on sand bars found by 
Nuttal, deemed a N, G. but quite like Batschia 
although habit a little different and corolla less 
lobed, if a subgenus it may be called Onokiles 
a Grecian name of Anchusa. Pedal, first leaves 
opposite, small hardly uncial, flowers few large* 
768. Lycofsis ? axillaris Raf. stem flexu- 
ose angular, leaves sessile linear lanceolate 
slightly scabrous and pubescent, flowers axillary 
sessile, calix villose tomentose canescent — 
Found in Florida by Mr. Ware, marked a Ly- 
copsis in Coll, herb, but habit rather of Litho- 
spermum, small plant, leaves elongate, over one 
inch long. Very different from £, mrginica , 
UMBELLIFEROUS PLANTS. 
769. MESOBISCU® Raf. dioical involucre 
1 or none,invo!ucels 2, male fl. with a thick len- 
ticular disk convex central, no calix ! no style ! 
petals 5 obcordatc, stamens 5 equal to petals, 
anthers globose bilobe, female fl. and seeds un- 
known .... Leaves commonly ternate , flow- 
ers white. — Very singular Genus, perfectly di- 
oical, which appears a paradox in this family of 
plants : several G. however are polygamous. 
Although the fruit is lacking yet this Genus ap- 
pears perfectly distinct and unlike any other 
except the next. I have 2 sp. of it, one of 
which is anomalous again by a triple componnd
