long to the Genus, the Z*. latifolium forms my 

 G. Cyphorima 1819 having 5 pits outside of 

 the mouth of corolla, with 5 corresponding knobs 

 inside. 



767. Batschia albiflora 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 ^and 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. Lycopsis ? 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 £, virginica^ 



ombelliferous plants. 



769. MESODISCUS Raf. dioical involucre 

 1 or none,involucels 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 

 umbel.
