large, straggling, thin, with elongated branches and scantily leafy;

WestTERN ReGion: Great Namaqualand; Homeib River, Schinz, 19! 
An abundant plant in Tropical Africa and India. 
Dr. Schinz’s example cited is quite typical P. bicalyculata, but among the 
quantity of specimens, admitted as P. bicalyeculata, some are very near Fe 
caulopsila. 
3. P. Hensii (C. B. Clarke in Dyer, Fl. Trop. Afr. v. 248) ; stems 
stout, strongly hexagonal even in the panicle; panicle rigid ; 
ultimate peduncles short, stout ; leaves few ; corolla often exceeding

caulopsila, T. Anders, in Journ. Linn. Soc. vii. 48 partly. Justicia 
capensis, Ecklon ex Nees in DC. Prodr. xi. 498. 
Coast Recion: Uitenhage Div.; near the Zwartkops River, Ecklon ¥ 
neers lopsila ; but 
T, Anderson had good reason for calling this only a form of P. caulopsila ; bu 
it appears to me nulte as well separable from P. caulopsila as is P. bicalyculata, 
which T, Anderson admitted as specifically distinct. 
5. P. natalensis (T. Anders. in Journ, Linn. Soc. vii. 48); 
branches stout, hexagonal, often scabrous or hispid on the angles (as 
is P. bicalyculata sometimes) ; leaves up to 2 by { in., ovate-lanceo- 
late, rhomboid at the base, persistently hairy ; inflorescence 16 by
