This account of P. pectinata is based on the examination of more than one hundred 

 flowering specimens belonging to 46 different gatherings; flower* from every individual 

 specimen have been analysed. Plate 23A, which represents 1 specimen of Wallieh's 

 original plant, and B, which represents one exactly = P. fjramidaU 11, rb In<L Or (not I 

 Royle), rather illustrate extreme forms of a variable species than distinct firietio. 

 With this explanation they are now advanced as allordiDg the simple* exj I. .nation 

 the synonymy of the group to which the species belongs. 



P. pyramidata closely resembles this species, and varies equally in habit. Hut neither 

 at Calcutta nor at Saharanpur, where both species are very well represented, is tin 



single form where the floral structure is intermediate. The diagnosis between the two 

 species is as follows: 



ro a 



beak of corolla gradually taperiDg to middle, then uniformly Blender; till** 

 hardly longer than calyx, sacculate in front at the staminal insertion; 

 lower half of galea suberect ; stamens inserted opposite top of ovary, 

 densely pilose at insertion as well as above ]' peciinaia ; 



beak of corolla uniformly slender from its base; tube narrow, straight, half 

 exceeding calyx, not sacculate ; lower half of galea inclined forwards ; 

 stamens inserted above middle of tube, glabrous at insertion and only 



sparingly hirsute above

In floral structure P. pectinata is more nearly allied to P. i<nuiro$tri$ than to 

 P. pyramidata; P. tenuirostris has the same peculiar transverse furrow at the stain ii tl 

 insertion (a character so far peculiar to these two species), and has identical stamens; 

 its only diagnostic marks are its yellow (not purple) corolla, its more slender beak, 

 its denser spike, and its less incised sessile cauline leaves. The capsulee, and d m 

 especially the seeds, in these three species are scarcely distinguishable (sec Plate 37).
