below into a cup, tips free, deciduous. Calyx bell- shaped, leathery, like the 

 bracteoles densely scaly, 5-fid, lobes valvate oblong or rounded. Petals 5, 

 contorted-imbricate, spathulate, longer than the sepals. StammaL-tube 

 divided into 4-5 phalanges opposite the petals ; filaments many, bearing 

 a globose head of sinuous 1-celled anthers, or a single annular 1-celled 

 anther. Ovary scaly externally, 4-5-celled; styles connate, stigmas capi- 

 tate ; ovules many and 2-seriate in each cell. Fruit very large, subglobose 

 or oblong, spiny, indehiscent or loculicidally 5-valved. Seeds arillate; 

 cotyledons fleshy, often connate. DISTKIB. Malay Peninsula and islands ; 

 species 3.

MALACCA, cultivated only? DISTKIB. Malay islands. 



A tree. Leaves 6-7 by 2-2^ in., base rounded, obovate- oblong, entire, feather- 

 veined, leathery, shining above, scaly beneath, not hairy ; petiole about 1 in., thickened 

 at the apex. Flowers in lateral trichotomous cymes; peduncles angular, subulate. 

 Bracteoles deciduous, half the length of the calyx. Calyx bell-shaped, leathery, densely 

 clothed with large peltate scales, 5-lobed, lobes obtuse. Petals oblong, tapering at the 

 base, longer than the calyx. Stamens longer than the petals. Ovary oblong, scaly. 

 Fruit subglobose, very lar^c, somewhat woody, densely muricate, indehiscent or tardily 

 5-valved, pulpy within. /Seeds arillate. The Durian is probably not indigenous in the 

 Malay Peninsula. Wallace (Kew. Gard. Mis. viii. 228) states that two varieties, both 

 small fruited, are indigenous in Borneo. 



2. D. malaccensis, Planch, mss. ; leaves scaly beneath, flowers large 

 (about 5 in. diain.), staminal column tubular for half its length, anthers 

 sinuous in globose heads. 



MALACCA, Griffith, Maingay ; BIRMA, Brandis. 



A tree, with the habit and foliage of D. Zibethinus, but with the flowers nearly 

 twice the size. Petals twice the length of the sepals. Staminal-tube divided, about 

 the middle only, into 5 phalanges. Ovary and fruit as in the preceding. Perhaps the 

 wild form of the Durian. 



3. D. Oxleyanus, Griff. Notul. iv. 531 ; leaves glabrous above pubescent 

 or hairy on the under surface, scaly on midrib only, flowers about 1 in. 

 diam., stamens 4-5-adelphous, anthers annular solitary on the end of each 

 filament. 



MALACCA, Griffith, Maingay. 



A tree, with the habit and foliage of D. Zibethinus. Calyx ventricose. Petals 

 oblong-spathulate, longer than the sepals. Staminal-phalanges 4 or 5, dividing about 

 the middle into numerous filaments each bearing a solitary anther with a thickened 

 black connective bordered by an annular cell. Ovary and fruit of D. Zibethinus, but 

 emaller. Referred by Planchon, in Herb. Kew, to Neesia, but erroneously. 



20. BOSCHXA, Korth. 



Trees. Leaves simple entire, scaly beneath. Flowers small, axillary. 

 Bracteoles 2-3, connate at the base, deciduous. Calyx deeply 4-5-parted. 

 Petals linear-ligulate, entire or laciniate. Stamens many, some free, others 

 irregularly coherent, outermost without anthers ; anthers oblong, 1-celled, 

 opening by a terminal pore, solitary, or in groups of 2-6. Potlen 

 globose 3-valved. Ovary 3-5-celled, style elongate ; ovules one or
