Camp VI a, 3100 ft. 



Near Bendrobium inamoenum, Krauzliu, of British New Guinea, but with a linear 

 acute, not cucuUate entire lip. 



Dendrobitjm (§ Pedilonum) rhodobotrts, EitlL, sp. nov. 



Caules alti, 3 mm. crassi. Folia lanceolata vel ovato-lanceolata, coriacea, acuta, basi 



rotundata, 8 cm. louga, 2'5 cm. lata, vagi'nis 2 cm. longis, ore rotundo. Racemus 



terminalis, densus, mviltiilorus, 2 cm. longus. Bractece oblongse, lanceolatse, 



olitusse, 5 mm. longa?, 2 mm. Iata3, roseae. Flares circiter 24, subcapitatim con- 



gestte. Fedicelli graciles, 1'5 cm. longi. Seijaliim jjosticum oblongum, obtusum, 



4 mm. longum, 2 mm. latum, lateralia similia, apice rotundata; mentum breve, 



crassum, obtusum, rectum, 5 mm. longum. Petala latiora, ovato-oblonga, obtusa, 



omnia rosea. Lahellmn 1'2 cm. longum, ungue brevi lineari, callo transverse 



laminiformi ad apicem emarginato, latiiina aurantiaca elongato-triangulari integra 



truncata 8 mm. longa apice 5 mm. lata, marginibus ad apicem involutis. Columna 



aurantiaca, ad apicem pedis angustata, stelidiis crassis oblougis obtusis, rostello 



lato recto, filamento breviusculo. 



Camps VI b and VI c, 3900 and 5500 ft., and VII to VIII, up to 4900 ft. 



Allied to D. bracteosmn, Reichb. fil., but the flowers are much smaller, the lip-apex 



broad, minutely denticvilate, with the callus as a low transverse emarginate bar between 



the foot and blade of the lip. A small piece of a plant with flowers little more than 



1 cm. long, collected between Camps III and VIII, has exactly the same floral structure, 



and is doubtless the same plant with smaller leaves and flowers. 



Dendrobitjm mitrieerum, J. J. Sm. in Bull. Dep. Agr. Ind. Neerl. xxxix. (1910) 10, 

 and in Nova Guinea, vii. p. xciv c. 



Camp VI c, 4900 ft. 



Distrib. New Guinea. 



The flowers seem to be pink, except the lip, which is apparently white with a yellow 

 tip ; the lip is remarkably short in proportion to the sepals. Smith gives the colour of 

 the flowers as yellow with orange and orange-red. The plant, however, seems identical 

 with the figure and description.
