New or Rare Malayan Plants. 

 Series V. 



By H. N. Bidley, f.r.s., f.l.s. 



In 2'oina: over the herbarium at the Botanic Gardens, 

 Singapore, 1 find a good many plants not recorded in the 

 Materials of the Flora of the Malay Peninsula, some over- 

 looked, others collected since the publication of the earlier 

 numbers. I have therefore put together notes and des- 

 criptions of these plants so that they may be on record. A 

 few orchids too received from Sarawak from Mr. Hewitt and 

 others are also described. 



Since Sir George King described the Dipterocarpeae 

 several new ones were described by Sir D. Brandis, and I have 

 given notes on these, rather fuller than in other cases as these 

 trees are of considerable importance to foresters, on account 

 of the value of their timbers. Curiously among the Dip- 

 terocarps omitted from the Materials by Dr. King is the 

 well-known Camphor tree, Dryobalanops camphofa of which 

 I hope to give a full account when I have got certain further 

 information about it. 



DILLEXIACEAE. 



WORMIA. 



The shrubs and trees of the genus Wormia are among 

 the most striking of our local plants, the brilliant colouring 

 of the large yellow, more rarely white flowers, being most 

 conspicuous. The genus is closely allied to the equally showy 

 one Dillenia, but is I think very distinct. King in the 

 Materials for a flora of the Malay Peninsula distinguishes the 

 two genera correctly by the absence of an aril in the Dillenias 

 and the presence of an aril in the Wormias. Martelli in Ma- 

 lesia has mixed the two genera together under the name
