FLORA TELLURIANA. 



CENTURIA QUARTA. 



301. PiAROPus R. (thick feet) Pontederia 

 azurea et crassipes auct. When I refered 

 these plants with doubt to my reformed Ponte- 

 deria 5, I had not before me Hooker's figure, 

 which proves that they hardly belong there, and 

 confirms my opinion that the whole wants re- 

 form, and to be examined again. These form 

 the type of a beautiful N. G., probably with 

 many overlooked, sp in S. America. — Corolla 

 tubo incurvo, limbo amplo ineq. nonbilabiato, 

 6partito. segm. obovatis, uno supero major. Stam. 

 6 ineq. 3 intubo, 3 longior exsertis, omnis curvis. 

 Ovar. ovato, Stylo longo flexuoso, Stigm. capit. 

 papilloso. Capsula Slocular poly sperm, sem. 

 central. Plant, natans, radic.fibris finibriatis^ 



fol. radic. petiolis infatisfusiformis celidosis^ 

 ft. amplis spicatis, racJiis triangularis non 

 spadix. What a striking G. by habit and cha- 

 racters ! 3 Types at least. 



302. Piaropus tricolor Raf Fol. cordatis 

 ovatisque, acutis, corollis purpurascens, petalo 

 major tricolor, stam. piloso. glandulosis, pistilis 

 viridis. From Guyana to Guayaquil, probably 

 several sp. that of Swartz and Antilles has 

 azure flowers, this has them pale purple, the 

 upper petal blue in the middle with a yellow 

 spot, fl. 3 inches. — Pont, azurea Hook, b. m. 

 2932 Synon. dub. ad Kunth, Hoenk, confer.
