252 THE JornxAL of bota:n^y 



Leavrs 5-7 cm. X l"5-3 cm., with petiole barely 7 mm. long ; cnlyx 

 6 mm. lon^, exclusive of the veiy short lobes 4 mm. broad. Fruit 

 over 7 mm. long and 6 mm. broad. This is related to P. nuda 

 Wavvra, but is readily distinguished by the less close venation of the 

 leaves, the calyx-lobes much broader than long, and the long oblong 

 corolla-lobes.

Nearly i-elated to my P. flavivrnter {supra), but at once distin- 

 guislied by the tubular calyx, uninterrupted by any basal or other 

 swelling. Allied also to P. Jio.via St. Hil., from which it differs 

 chieHy in the scarcely-acuminate elliptical leav^es, the shape of the 

 sti])iUes, the tofcil absence of cilia on the involucral margins, and the 

 entire iioral involucels. Leaves 4-7 cm. xl"5-2-5 cm., with jDctiole 

 not 5 mm. long. Bracts of general involucre 3 mm. long ; involucel, 

 3 mm. deep. Exserted part of calyx, 5-G mm., width 3 mm. in the 

 middle.
