NOTES ON PLANTS OF INTEREST IN THE 

 BOTANIC GARDENS, SINGAPORE. 



Porphyroglottis Maxwelliae, Ridley. 



Among the orchids which flowered in the Botanic Gardens, 

 Singapore, in 1913, was Porpliyraglottis Maxwelliae. This strange 

 orchid of still somewhat doubtfnl affinities was described by Mr. 

 Ridley in 1896, from dried specimens and drawings sent to him from 

 Sarawak. Otherwise it has remained unknown, and living plants had 

 been in no Botanic Garden, until a small collection from Dutch 

 Borneo was otfered to him for purchase in 1911. By chance 

 Porphyroglottis Maxivelliae was in the collection. 



A new Variety of Eria gracilis, Hook, f. 



An orchid which iias recently flowered in the Botanic Gaidens is 

 Eria gracilis \\\ a variety not described. The lip is obcuneate, with the 

 middle lobe reduced to a minute point overtojip^d by the truncate 

 side-lobes. It may be called var. obcuneata. 



There is a label on the Singapore plant calling it a "Dendrobium 

 from Java." Possibly this label has been transferred from another 

 plant, for Eria gracilis is a local orchid of Singapore, extending 

 northwards to Penang, but unknown in Java. 



The flowers are flesh-coloured with sparse crimson hair outside 

 and the lip has a crimson line down its very margin, as in the allied 

 E. oligantha, Hook. f. 



A new Variety of Sarcochilus stenoglottis. Hook. f. 



A variety of Sarcochilus stenoglottis flowered in the Gardens early 

 in August. Unfortunately the origin of the plant is unknown. 



Sarcochilus stenoglottis was described by Sir Joseph Hooker in 

 the Flora of British India, vi. (1894) p. 34 ; and a plate is given in the 

 Annals of the Royal Botanic Gardens, Calcutta, v., (1895) t. 62, a re- 

 production of a sketch made in Calcutta in 1883, from a plant obtain- 

 ed in Sumatra by Kunstler.
