19? " GENUS COLLINSIA. [December, 



size of mustard seed.) Corculum flat, and erects green- 

 ibh; radicle inferior. Perisperm cartilagiaous, including 

 the cQrculum, perforate^ in the centre on the inner side, 

 by which orifice the seed is attached to the receptacle. 



Time of flowering, about Ma3^ The definite number 

 of seeds, about 3, or primarily 4, as is observable on ex- 

 amining the germ, the indistinctness of the capsular valves 

 also the same number, and the obliteration of the dissepi- 

 ments, are circumstances, independent of the extraordinary 

 form of the corolla, which deviate remarkably from the 

 genuine character of the Antirrhine^, and approxi- 

 mate this plant in a manner towards the Labiatje. Not- 

 withstanding the situation which it appears thus to hold 

 betwixt these two orders, its place appears to be imme- 

 diately after the genus Anarrhimim of Persoon's Synopsis.
