distribution. Of the new genera discovered two have very 

 pretty spathes, and if they can be successfully cultivated 

 will prove very interesting and ornamental stove plants. 

 Piptospatha insignis, N. E. Br., a pretty little " rock 

 arad," found on sandstone boulders in the beds of moun- 

 tain streams, has a tuft of lance-shaped leaves and dainty 

 white spathes tipped with pink. Oamogyne Burbidgei, 

 N. E. Br., is a plant of larger growth, being a foot high but 

 otherwise of similar habit. The spathes are of a bright 

 rose colour. This plant grows beside mountain streams 

 in positions where the passing water laves its roots. 



Amongst new species of aroidese may be mentioned the 

 sub-aquatic Cryptocoryne caiidata, N. E. Br., which has 

 heart-shaped bullate leaves of a dark green colour, the 

 spathe being terminated with a long tail, which reminds 

 one of the same appendages in the arissemas of the Hima- 

 layas. Three or four new species of alocasia were found, 

 the remarkable being A. scabriuscula, A. guttata, and A. 

 pumila. Pothos ceratocatdis, a fresh green climbing 

 species, was also introduced alive, and is a plant of dis- 

 tinct marcgraavia-like habit. Specimens of Schismato- 

 glottis and CliamcBcladon are at present undetermined. A 

 singular new asclepiadaceous genus (Astrostruma sparti- 

 oides, Benth.), was discovered growing as an epiphyte on 

 forest trees in Labuan, and in dry woods near the sea at 

 the northern point of the last-named island, the remark- 

 able little Microstylis Burbidgei, Echb. f., was found. One 

 of my first discoveries in Borneo itself was the new zin- 

 giberaceous genus Burbidgea {B. nitida, Hook, f.), 

 and other novelties were Dendrohiuin cerinum, Cypri- 

 pedium Lawrencianum, and Bolbophyllum Leysianum, a 

 highly curious plant. A fine new Bolbophyllum was in- 

 troduced alive to Chelsea from the Tampassuk river 

 (jB. Petreianum, Burb. MS.), which I propose shall bear
