146 OCCASIONAL NOTES. 



Rh. Teysmanni, Miq., a yellow flowered plant, grows oil 

 Penang Hill. It is an ally of Rh. javanicum, Benn., which is 

 the fourth species. 



All these grow on the trees as epiphytes, usually at consi- 

 derable altitudes, i. e., from 2,000 feet upwards. 



The only other plant of the order Ericacea? yet recorded 

 from the Peninsula is a Diplycosia microphylla, Becc, a re- 

 markable little creeping plant, which appears to be common 

 at high altitudes. It has more of the appearance of one of the 

 bilberry family, with tough, wiry branches, and small oval 

 leaves. 



The allied orders of Vacci?iiacea3 and Epacridea? are repre- 

 sented respectively, in Singapore, by Vaccinium tnalaccense 

 a bush of considerable size, w T ith pink or white sweet-scented 

 heather bell-shaped flowers, and small eatable black bilberries ; 

 and the remarkable Leucopogon malayaniis, Jack, a large 

 bush with hard, sharp-pointed leaves, very small white flowers, 

 and sweet but very small orange berries. Both grow on sandy 

 ground near Changi towards Tanah Merah, Leucopogon form- 

 ing here dense thickets. Another species of Vaccinium also 

 grows in Pekan, with longer and more crimson flowers.

POGON1A PUNCTATA, BL, IN SINGAPORE. 



The genus of orchids Pogonia has not hitherto been 

 recorded from the Malay Peninsula, but as the surrounding 

 countries produce a number of species, it is not to be wonder- 

 ed at that at least one kind should occur here. Some months 

 ago, I found in a stream on the western slope of Bukit Timah 

 a small plant of some species of this genus, and by carefully- 

 transferring the small tuber with its solitary leaf to the Botanic 

 Gardens, I was able to induce it at last to flower, when it 

 proved to be P. punctata, Bl.--a plant obtained by Blume 

 from the slopes of Mount Pangerang in Java, and figured by
