Gouystylaceae. 79 



stylaceae in the Series Malrales, between the FAaeocarpaceae and 

 the Tiliaceae. 



GiLG gives 7 species as belonging to this family all being found 

 in Asia or the Malay Archipelago. Tiiey are as follows: 

 Gonystylus hancanus (Miq.) Gilg (= O. Miquelianus T. and B.) in 



Java, Sumatra, Banca. 

 Gonystylus affinis Radlk. (= G. Beccarianus V. Tiegh.). 

 Gonystylus borneensis (V. Tiegh.) Gilg (=- Asclerum horneense V. Tiegh.). 

 Gonystylus pluricornis Radlk. (= Amyxa kutcinensis V. Tiegh.). 

 Gonystylus calophyllus Gilg, all in Borneo. 

 Gonystylus Maingayi Hook, f., Malacca. 

 Gonystylus Forbesii Gilg, Sumatra. 



Teysmann and Binnendijk give an account of the use of the 

 wood of the Javanese species. "Beside the Benzoe the Malays use 

 a fragrant wood, Kaju Garu, as a medicament and as an incense 

 to prevent excessive rain. In the markets this wood is sold in little 

 pieces at a low price. It is obtained from the interior of the trunk 

 of old trees which have fallen down, or from those that are felled 

 for the purpose. The wood is filled with an oily substance, which 

 when burned, diffuses an odor like rhubarb. This species is regarded 

 as belonging to the less valuable of the odoriferous woods, see 

 Rumph. Herb. Amb. II, p. 29; it appears to be closely related to the 

 " Bastard -Ayel-Hoh"', alluded to by the same author somewhat 

 later. In Bengal there is another variety which seems to be derived 

 from Aquilaria AgaUocha. Pulverized and boiled in water, the oil 

 comes to the surface. Apparently in Borneo, Sumatra and Banca 

 this Aq. AgaUocha also occurs; from the first mentioned island there 

 are specimens in the Botanical Garden in Buitenzorg." 



Similar notes in regard to the use of the Philippine plant did 

 not accompany the specimen of Merrill. I take the opportunity of 

 calling the attention of my countrymen to this interesting plant. In 

 the Philippines it is possible thc.t the wood may be similarly used. 

 It would be interesting also to ascertain the distribution of this 

 probably high tree. 



The synonymy is as follows: 

 Cronystyhis baiieaiiiis (Miq.) Gilg in Nachtr. Engl.-Prantl Pflzfam. 



p. 232 (1897). 

 Aquilaria baticana Miq. Fl. Ind. bat. Suppl. 141, 355 (18G0). 

 Aquilaria macrophylla Miq. 1. c. 356 (both species are founded on 



sterile specimens).
