torn, and having very numerous parallel brown, mostly unbranched nerves. 

 It is supposed by Professor Royle to be part of the same plant as those which 

 I have considered P. aviculare. Should that prove to be the fact, it will go 

 far to destroy several species in this genus, by showing the uncertainty of 

 characters drawn from the stipules.

30. P. Roylii. 



Floribus axillaribus parvis pedicello brevissimo, achenio trigono granulato- 

 striato calyci eequali, ochreis acutis lobatis baud laceris : venis 2 obsoletis, 

 foliislineari-lanceolatis acutis integris punctis glandulosis numerosissimis, 

 caule 3 — 4-angulato : angulis scabris. 



Stem prostrate, perennial, branched, with 3 or 4 scabrous angles. Leaves 

 linear-lanceolate, acute, entire, covered both above and below with pel- 

 lucid glandular dots. Stipules rather short, acute, lobed, but scarcely 

 torn, with two short nerves. Flowers axillary, small, almost sessile, the 

 pedicels jointed just below the flower ; the internodes so much shortened 

 at the extremities of the branches as to give the appearance of a spiked 

 inflorescence. Fruit small, 3-gonous, equal to the calyx ; the faces tri- 

 angular-ovate, acute, granulate-striate.

31. P. mucronatum. 



Floribus axillaribus parvis sessilibus, achenio trigono Isevi, ochreis ovatis 

 acutis laceris internodiis longioribus nervis nullis, foliis lanceolato-line- 

 aribus longh mucronatis marginibus recurvis, caule pubescenti lignoso. 



P. mucronatum. Royle MSS. 



Stem prostrate, woody, branched, pubescent, the internodes very short. Leaves 

 sessile, linear-lanceolate, their margins reflexed, the midrib running out 

 into a long pellucid subulate point. Stipules white, longer than the in- 

 ternodes, (very rarely shorter,) acute, torn, without any nerves. Flowers 

 axillary, small and sessile. Fruit trigonous, smooth, very young on my 

 specimens. 



Chango in Kunawur, in August.
