IV. — Noviciffi Indicse XIX. A new Indian Dendrobium. — By D. Prain. 

 [Received February 26th. ; Read March 6th, 1902.] 



Among tbe Orchids that flowered in the Royal Botanic Garden, 

 Calcutta, during 1901, one of the most beautiful was a Dendrobium that 

 differs from any of the Indian species hitherto described. To be 

 assured that the plant is in reality a previously unknown species a 

 drawing from life bas been compared with the material and drawings 

 preserved in the great national collection at Kew. The following des- 

 cription of the plant is now therefore offered. 



Dendrobioi regiuji Prain ; caulibus erectis parum compressis ; foliis 

 oblongo-lanceolatis versus apicem oblique retusum vel incisnm augus- 

 tatis ; floribus 2-3 pedunculo brevi subracemosis, pedunculis e caulis 

 aphylli nodis orientibus ; sepalis lineari-oblongis obtnsis roseo-purpureis 

 lineis rubro-purpureis notatis ; petalis ellipticis roseo-purpureis lineis 

 rubro-purpureis reticulatis ; mento brevi lato ; labio lituif ormi aliquantum 

 angustato, limbo roseo-purpureo lineis rubro-purpureis reticulato, glabro ; 

 tubo pallide flavo. 



Hab. In provinciis Hindustaniae inferioribus. 



Stems 8-12 cm. long, 1*3 cm. thick ; nodes 3 cm. apart. Leaves 

 8-40 cm. long, 1"5 cm. wide, tips distinctly obliquely notched. Peduncles 

 2 cm. and pedicels 4 cm. long ; bracteoles adpressed, lanceolate, tinder 

 1 cm. long. Flowers 8 cm. across, magenta with darker lines and 

 transverse markings ; mentum 1'25 cm. long ; sepals 1 cm. and petals 

 2"75 cm. wide ; lip 4 cm. long. 



This species is very nearly related to D. nohile Lindl. but is quite distinct from 

 any of the known varieties of that somewhat variable species. In the nearly uniform 

 coloration of tbe sepals and petals (thongh not in the colour itself) it approaches 

 most closely the form of D. ndbile distinguished and figured by Lindley, Sertum t. 

 18, as D. coerulescens. That plant, however, has a lip with purple throat and yellow 

 margin ; the present species has a cream-coloured tube and throat with a magenta 

 limb coloured and marked like the petals and sepals. The lip of D. regium s, more 

 over, narrower than in any form of D. nobile and is not pubescent.
