This account of P. pycnantha is based on the examination of 11 specimens of 



VAR. 



typica and 27 of var. Semenowi. There is no doubt about the Trans-Indus plant; it 

 is the same species as Boissier's Persian plant-to which also belongs Aitchison's 

 "Delimitation Commission" plant (n. 679 from Khorasan, 6,000), of which quite 

 determinable specimens have been received at Calcutta. But the Punjab Himalayan 

 plant placed by Sir J. D. Hooker in 1884 with Boissier's Persian plant is not quite 

 the same thing, but belongs, as Mr. Maximowicz had pointed out in 1881 to Reg-el

P. Semenowi. The diagnosis given by Mr. Maximowicz is most accurate, and while 



I think that P. Semenowi is conspecific with P. pycnantha, thcro is no possibility of 



mistaking the one variety for the other on dissection. Of the plant mentioned in Mel. 



Biol, x, 129, as possibly a variety of P. orthantha, Mr. Maximowicz has kindly sent 



me a drawing, as well as a leaf, a bract and 3 flowers from the solitary St. Pctersb 



specimen. The flowers and bract and leaf are those of P. pycnantha var. Semenom 



In this species the leaves, especially of the lower whorl, are subopposite ratlier than 



truly opposite, and as Mr. Maximowicz' sketch shows this plant of Ileydo to he a very 



dwarf form, the condensation of the internodes leaves hardly greater intervals between 



petioles of different whorls than naturally exist between those of the same whorl, so 



that in this condition the species may be well enough treated, as Maximowicz, l.c , has 



treated it, as an alternate-leaved one. In Herb. Calcutt. there is a gathering by Hay 



in Lahul, where one specimen is exactly like the drawing of Heyde's plant at St. 



Petersburg, while another has a stem elongated sufficiently to show the verticillate nature 



of the phyllotaxis. In Dr. Royle's gathering from Kunawar the same thing occurs, and 



Bentham in describing the plant also speaks of the leaves as alternate. The specimens 



being destitute of corollas, Bentham did not publish Royle's Mss. name (P. patens Royle 



in sched.) which can never therefore supplant those of Boissier or of Hegel. It is, however, 



only just to observe that Royle and Bentham were the earliest authors to ascribe specific 



rank to the plant here named var. Semenowi. With P. Alberti, which Sir J. D. Hooker 



has reduced to P. pycnantha, the case is different. There the leaves are certainly very 



like those of P. pycnantha var. Semenowi, and in short-stemmed specimens might well 



be considered opposite or subopposite. But where the stems are more elongated the 



leaves are seen to be distinctly alternate. There are other differences, and P. Alberti is 



more 



nearly allied to P. Oederi than to P. pycnantha. The diagnosis is as follows : 



leaves verticillate, spike interrupted whorled centripetal, anterior filaments 



hirsute 



P. pycnantha; 



leaves alternate, spike continuous spiral centrifugal, all filaments glabrous P. Alberti.
