I now suspect this is not specifically distinct from the 

 Bengal species — L. imberbis — which I now find is also a 

 native of the Peninsula.

 minal column as seen after the removal of the crown— 6 

 pollen masses. 



Z55. Hutchtnia Indica (Wight's Contrib. p. 34.) 

 The essential character of this genus is to h ive the sta- 

 minal crown in a double series, the inner consisting of 5 

 simple lobes resting on the anthers, the outer of 5 lobes 

 alternate with the inner series, but each S-eleft, with the 

 middle segment smaller, thus making together a 

 20-lobcd coromi -This, being the only species of the 

 genus, has no specific character.

 ing the double corona, but not well represented 3 ovary

 rarely 2-3 together, drooping, somewhat cylindric, rather 

 shorter than the leaves : petals scarcely cohering by their 

 margins, and forming a 5-cleft corolla.— W. & A. Prod 

 page 271.

) arboreous : 



leaves from oval, ob'use to obovate, tapering towards the 

 base, crenate, glabrous on both sides : peduncles axillary 

 from the summits of the branches, several flowered, pedi- 

 cels pubescent, jointed, furnished with 2 cuneate bracts 

 below the joint : sepals coriaceous, obtuse, silky on the 

 back, stamens all equal, styles and carpels 0, many -seeded. 



Balaghaut mountains, near Madras— This is a verv 

 handsome species, nearly allied to D. relusa, but 1 think 

 certainly different.

ISONANDRA (R W.) No. Sapotace*. 



Gen. Char. Calyx deeply 4-parted : corolla 4-cleft : 

 stamens 8, all fertile, anthers posticous : ovary 4-celled, 

 with a solitary erect ovule in each cell : nut chartaceous, 

 by abortion, one called, one-seeded: seed obovate, erect; 

 cotyledons foliaceous, enclosed in a copious albumen ; 

 radicle inferior— Trees with alternate somewhat coria- 

 ceous, glabrous or pubescent leaves, and small flowers. 

 Flowers forming axillary clusters or capituke, generally 

 found mixed with fruit in nearly all stages, from the fall 

 of the corolla to perfect maturity,flowersyellow or whiiish. 



This genus is readily distinguished from alt others of the 

 order by its perfectly symetrical flowers, and the stamens 

 all perfect (hence the name) in place of one half sterile. 

 In habit and also in structure, it is allied to Sideroxylony 

 but the quaternary, not quinary, arrangement of the 

 flowers and the absence of abortive stamens in any form, 

 sufficiently separate them.
