This plant was referred by King to //. macrantlia, Korth. 

 Verb. Xat. Gesch. 18'7 t. 39 which plant is undoubtedly the 

 same thing as II. Cumingii, Laws. Flor. Brit. Ind. I. p. 624. 

 Korthal's figure and a specimen from him in Herb. Kew 

 clearly represent the river-bank plant known as II. Cumingii. 

 The black rugose stem, crenate leaves very variable in size, red 

 pubescent inflorescence, absence of hairs on the petals and 

 larger fruit distinguish II. nigricaulis, Korth. readily from the 

 true II. macrantlia. 



H. macrantha, Korth. is not rare in the south of the Malay Penin- 

 sula, Borneo and the Philippines. There is a specimen from 

 the Hookerian Herbarium at Kew labelled Ceylon collected by 

 Colonel Walker. It does not seem to have been met with in 

 Ceylon again and the specimen was perhaps from Singapore 

 where also Colonel Walker collected. It occurs on the banks 

 of tidal rivers and is called Akar Bintang by the Malays from 

 its yellow star-shaped flowers. 



H. ferruginea, King. An examination of the type plant of 

 Solatia GriffWiii, Lawson Fl. Brit. Ind. I. 628, shows that this 

 plant collected by Griffith in Malacca is no Solatia at all but 

 lUppocratea ferruginea, King. 



RHAMNACEAE. 



Ventilago. The species of this genus have been very much con- 

 fused in the Flora of British India and in King's Materials for 

 a Flora of the Malay Peninsula, and the whole genus confined 

 to the Indo-Malayan region with outliers in China and For- 

 mosa requires revision. The type of the genus is V. madras- 

 pa tana, Gaertn. a native of India as far as Mergui. It has not 

 been met with apparently in Java, for the plants so identified 

 belong to a distinct species. V. calyculata, Till, has much the 

 same distribution, but occurs also in Siam and Cochinchina. 

 Its curious yellow fruits covered half way by the cupshaped 

 calyx and entirely pubescent distinguish it readily. 



Ventilago leiocarpa, Benth. in Journ. Linn. Soc. V. 77; Fl. Hong- 

 kongensis was described shortly from plants from Hongkong 

 collected by Champion, some of Griffith's Malacca plants and 



R. A. Soc, No. 75, 1917.
