COLLECTED IN DUTCH NEW GUINEA. 175 



"A little carmine-coloured orchid ; leaves above dark green, below deep dull crimson." 

 Allied to L. cerasiuum, Ridl., but distinguished by the much longer pseudobulbs and 



larger pustulate leaves, the lanceolate bracts, and the acute more tieshy lip. The 



column seems exactly similar in the two species. 



Dendrobittm (§ Bolbodium) brevicatjle, Rolfe, Kew Bulletin, 1899, 110. 



Camps XIII, 10,500 ft., and VIII to IX, 4900 to 5500 ft. 



" Oviter base violet ; inner lip tipped scarlet ; petals pale silvery grey, tinged with 

 violet at the tips." 



Disfrib. New Guinea ; also obtained on Mt. Scratchley by Giulianetti. 



Unfortunately Rolie's description was made on a mixture of two plants, one of which 

 is Dendrobium chrysornis, Hidl. As his account of the species fits Kloss's plant, 

 excepting the stem and the leaves, I confine myself to describing these parts: — 



Caules congesti, 6 cm. longi, cylindrici, 4 cm. crassi, internodiis 4-5, vaginis pallidis 

 lauceolatis vel ovato-lanceolatis tecti. Folia ad 4, insequalia, 3-5 cm. longa, 5 cm. 

 lata, lineari-lanceolata vel elliptico-lanceolata. 



I also notice that the mentum is shortly bifid — a point not recorded by Rolfe. 



Kranzlin refers this species, which he has apparently not seen, to the section Pedi- 

 louum, though, as he says, it resembles a Bolbodium. Its afiinity is undoubtedly with 

 J), sitbacaule, LiudL, and the allied species described in this paper.
