188 G. King — Indian Species of Ganarium. [Xo. 4, 



strictum, Roxb., but differs in having broader leaflets more tomentose 

 beneath, a narrower drupe, and shorter branchlets.

 of male flowers. 3. ripe drupe; of natural size. 4. calyx. 5,6, & 7. petals, 8.

Besides the foregoing species, of which pretty full materials exist 

 in the Calcutta Herbarium, there are imperfect materials of another 

 species from Assam, viz : — 



C. reziniferum, Brace MSS. in Herb. Calc. A large tree 6 or 8 

 feet in girth, with leaflets resembling those of G. sihkimense in shape 

 and size, but having their under surfaces covered with much less and 

 much minuter tomentum, and with the rachises on which they are 

 inserted almost glabrous. The male inflorescence is a panicle of cymes 

 12 to 16 in. long, the female inflorescence being' racemose and only half 

 as long, and both being rufous- puberulous. Drupe ovoid, l - 5 in. long, 

 and nearly 1 in. in diam. when ripe, glabrous. Male and female flowers 

 unknown. Assam and Khasia Hills, G. Maun. 



This is the Dhoona, or Dhua, tree of Assam, and is a species apparent- 

 ly well enough known by its vernacular name and probably common in 

 that province. It yields a rezin which is used to make torches. Fruiting 

 specimens of it were collected by Mr. Gustav Mann at Nangpoo and 

 at other places in th.e Khasia Hills. Male inflorescences with a few 

 worm-eaten flowers accompany other specimens sent to the Calcutta 

 herbarium by the same indefatigable collector. Leaf-specimens collect- 

 ed at Jota Bhor (near Jorhat) in the year 1845 by Mr. Masters, (a 

 collector sent from the Garden,) also exist in the Calcutta Herbarium. 

 But perfect specimens of flowers of both kinds are still wanting. Will 

 no Forest officer now collect them ? 



Plate XII T. G. reziniferum, Brace. 1. Leaflet. 2 inflorescence of 

 male flowers. 3. ripe fruit ; of natural size. 4. calyx. 5,6, & 7. petals. 8. 

 staminal tube. 9. rudimentary ovary ; enlarged. 10. two anthers ; much 

 enlarged. 



There also exist in the Calcutta Herbarium specimens in fruit of 

 a species from Arakan with glabrous oblong leaflets 6 or 7 inches long 

 and about 3 inches broad, with minutely serrate edges, acuminate apices 

 and broad emarginate bases, and drupes like those of G. strictum, Roxb. 

 The nearest allies of this are apparently (1) 0. bengalense, which has 

 however smaller leaflets and much narrower drupes ; and (2) G. euphyllum, 

 Kurz, a species of which the drupe is as yet unknown.
