 Roem. Synops. fasc. i. 40. 



In all the Provinces : common. Distrib. — Malayan Archipelago, 

 British India, Philippine Islands, Australia. 



A very variable and most perplexing species, the Protsean forms 

 of which were first reduced to order by Professor D. Oliver (Journ. 

 Linn. Soc. Y, Suppl. II. p. 36). Of the forms recognised by Dr. Oliver 

 only some are found in the Malayan Peninsula and Andaman Islands. 

 Sir Joseph Hooker (in PI. Br, Ind.) follows Professor Oliver for the most 

 part ; and from that book I copy the following account of the varie- 

 ties. The Calcutta Herbarium is overloaded with specimens of this 

 plant, many of which it is difficult to fit in under any of Professor 

 Oliver's varieties ; and for one of these 1 have ventured to suggest the 

 varietal name macrorachis. 



Var. 1 : Leaves usually 3-, rarely 1- or 5-foliolate ; leaflets 4-9 in., 

 lanceolate or oblong, or obovate-lanceolate, quite entire or obscurely 

 crenulate ; panicles towards the tips of the branches usually elongate, 

 many-flowered ; ovary usually covered with mamillary glands, 5-celled, 

 connate with the disc at the base. — The commonest form in the Malay 

 Peninsula. — Distrib. ; British India. 



Var. 2: Leaves usually 3-5-foliolate (except sub-var. 1); leaflets 

 elliptic or elliptic-lanceolate ; panicles small, few or many-flowered, 

 flowers smaller ; ovary 4-5-celled, scarcely mamillate, constricted at tlie 

 base and thus free from the disc. — G. triphylla, Wight in Hook. Bot.
