COLLECTED IN DUTCH NEW GUINEA. 175 
“A little carmine-coloured orchid ; leaves above dark green, below deep dull crimson.” 
. Allied to D. cerasinum, Ridl., but distinguished by the much longer pseudobulbs and 
larger pustulate leaves, the lanceolate bracts, and the acute more fleshy lip. The 
column seems exactly similar in the two species. 
DENDROBIUM ($ BOLBODIUM) BREVICAULE, Rolfe, Kew Bulletin, 1899, 110. 
Camps XIII, 10,500 ft., and VILI to IX, 4900 to 5500 ft. 
“Outer base violet; inner lip tipped scarlet; petals pale silvery grey, tinged with 
violet at the tips." : 
Distrib. New Guinea; also obtained on Mt. Scratchley by Giulianetti. 
Unfortunately Rolfe’s description was made on a mixture of two plants, one of which 
is Dendrobium chrysornis, Ridl. 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 
lanceolatis vel ovato-lanceolatis tecti. Folia ad 4, inzequalia, 3-5 cm. longa, 5 em. 
lata, lineari-lanceolata vel elliptico-lanceolata. 
I also notice that the mentum is shortly bifid—a point not recorded by Rolfe. 
Krinzlin refers this species, which he has apparently not seen, to the section Pedi- 
lonum, though, as he says, it resembles a Bolbodium. Its affinity is undoubtedly with 
D. subacaule, Lindl., and the allied species described in this paper.
