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

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

 contorted-imbrieate, spathulate, longer than the sepals. Staminal-iuhe 

 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-celledj 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. — Disteib. Malay Peninsula and islands ;

Malacca, cMltivated only? — Distrib. 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. Oalyx bell-shaped, leathery, densely 

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

 |base, longer than the calyx. Utamens longer than the petals. Ovary oblong, scaly,. 

 Fruit subglobose, very large, somewhat woody, densely mnrioate, indehiscent or tardily 

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

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

 small fruited, are indigenous in Borneo. 



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

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

 sinuous in globose heads. 



Malacca, Griffith, Maingay; Bikma, Srandis. 



A tree, with' the habit and foliage of D. Zibetkinus, 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 th«) 

 wild form of the Dvrian. 



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

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

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

 filament. 



Malacca, Griffith, Maingay. 



A tree, with the habit and foliage of Z>. Zibetkinus. Calyx ventrioose. Petals 

 oblong-spathulate, longer than the sepals. Staminal-phitlanges 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. Ova«ry and fruit of D. Zibethinus, but 

 smaller. — 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. Cali/x deeply 4-5-parted. 

 Pefafe 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. Pollen
