The seeds are flat, round or oblong willi the hilnm ahont in the 

 middle (peltate) and snrrounded by a niembranons fringe-like notched 

 wing, abont as broad as the seed. For the distinction of species 

 only differences in size are to be considered (except in Lindeniopsis 

 where the edge of the wing is not fringed") ; 6. olaciformis and C. 

 mnluensis have the smallest seeds; 6'. Grijfitlüi the largest, as far 

 as we know. 



As to the process of pollination it may only be surmised. The 

 contorted movable projecting anthers and the long protruding stigma 

 point at the probability of wind-pollination, but the piominent flowers 

 scenting of elder and orange-blossom may point at a connection 

 with insects. The possibility of self- and inter-poliination is corro- 

 borated by the great mass of flowers and by the fact that (at least 

 in the herbarium) the anthers aie already open in the buds. 



§ 10. The station: About the ciiaracter of the locality in which 

 the various species are found we only know as follows: 



C. Jiavesceiis was gathered by Korthals on the barren sands along 

 the river Karrau in Borneo; by King's collector in bamboo-woods 

 in IMalacca 100 — 200 metres above the sea-level, by various collect- 

 ors in Western Java at the foot of the mountains, on various spots 

 in light secondary wood. 



C. maluensis at 40 — 100 meters above the sea-level in passable 

 primeval forest, about 20 — 25 meters, high ; the ground covered with 

 foliage (,, Galerie wald" Schimpkk), with occasional low wood, mostly 

 consisting of Pandanus and low feather-leaved palms (Camp Malu); 

 idem with many tree-ferns and bamboo and Selaginella a metre 

 high, as undergrowth (April-flusz) : Lkdermann. 



C.fuscescens in "Buschwald" changing into mountain-wood up to 

 1500 metres above the sea-level, few large trees, many epiphytes 

 and moss, many glades, ground often overgrown. On steep rock}' 

 slopes (Felsspitze) : Ledermann. 



C. lutescens in dense wood on hills, about 25 metres high, rather 

 mossy; in the underwood many dwarf-fan-palms and lianes, Frey- 

 cinetia, Araceae, Agathis, Pandanus : Ledermann. 



§ 11. Relationshljis and synonymy. On account of the structure 

 of ovary and fruit Coptasapelta belongs to the very natural tribe of 

 Cinchoneae Hooker (Genera plant. II p. II) among which 44 genera 

 are reckoned. This tribe is divided into two subtribes : 



I. Eucinchoneae with a valvate aestivation. 



II. Hillieae with an imbricate or twisted aestivation.
