This description of P. longiflora is based on an examination of 109 separate spec 



mens and on the dissection of flowers from specimens of 53 different gatherin 



P. tubiformis Klotzsch is only a tall form of the species 



« 



Of 40 gatherings at Calcutta, where the colour of the corolla has been noted 31 



g-ma in 



yellow-flowered, two Sikkim gatherings have white flowers, and one from K_.. 

 Phari has yellow tube and lip with purple galea. Mr. Maximowicz finds that t\ 

 lip of specimens from Burchan-Budda in N. Tibet has two cuneato purple markV 

 and the same thing is seen in some of the Calcutta specimens from J 



o\vt-r 



ongri. 



Of Indian species this comes nearest to P. siphonantha ; the diagnosis is as follow 



all lobes of lip emarginate, galea throat 2-sinuate, all filaments hirsute P. longiflora 

 only central lobe distinctly emarginate, galea throat 2-dentate, oi.Iy 



anterior filaments hirsute 



P. tiphonanttut 



Fruiting specimens also are easily diagnosed; in P. longiflora the

capsule is sin 

 anteriorly and the seeds are black, striate, but not reticulated; in P. siphonantha 



capsule is not sinuate, the seeds are pale and distinctly reticulated. 



Of extra-Indian species P. chinensis Maxim., a distinct species in habit stature 

 leaves, and calyx much like certain forms of P. megalantha, comes near to this but 

 differs in having the lateral lobes of the lip rounded, not truncate, and in hiring tj 

 apex of the beak of corolla entire. A specimen of the original gathering of P. chin u*,. 

 has been kindly sent to Calcutta by Mr. Maximowicz. Certain specimens from Hortl 

 China (Potanin, 1885) issued as "P. chinensis " from the St. Petersburg Herbarium are 

 however, only P. tubiformis Klotzsch, and therefore are merely tall forms of P. longiflora 

 Kudolph. 



The only author who has followed Steven in giving Fischer's name for the species, 

 and who has at the same time quoted Rudolph's name (as a synonym), has been Walpers. 

 He (I.e.) has taken the deliberate, if somewhat unusual, step of indicating that th* 

 name which he keeps subordinate was published in 1811, and at the same time shows 

 that he supposes the name which he accepts to have been first published in Steven's 

 work, i.e., in 1823, or 12 years later than the date of his synonym.
