7. IXONANTHES, Jack. (Ixionanthes, Auct.) 



Glabrous trees, turning black in drying. Leaves alternate, entire or cre- 

 nate-serrate, nerves reticulate ; stipules minute or 0. Flowers small, in 

 axillary cymose dichotomous peduncled panicles. Sejials 5-6, shortly connate 

 at the base. Petals 5-6, perigynous, contorted, persistent, hardened round 

 the fruit. Stamens 10-20, inserted on the outside of a perigynous annular 

 or cupular eglandular disk. Ovary free, 5-6-celled, cells sometimes 

 2-locellate ; style simple, stigma capitate lobed ; ovules two in each cell. 

 Capmle coriaceous or woody, oblong or conic, septicidal, carpels opening 

 inward. Seeds (according to Griffith) winged or crowned with a mitri- 

 form aril, albumen fleshy ; embryo lateral, cotyledons foliaceous, radicle 

 superior. DISTRIB. Species 6-8, all tropical Asiatic, and chiefly Ma- 

 layan.

A small tree. Leaves 3-7 by 1^-2 in., very variable, always narrowed into the 

 petiole, which varies from Yr~4 * n -> brown when dry, shining on both surfaces, margins 

 thickened, nerves very slender almost horizontal, tip obtuse rounded or emarginate. 

 Peduncles slender, straight, often exceeding the leaves. Flowers about \ in. lon^. 

 Without .authentic specimens the identity of tliis with Jack's plant cannot be veri- 

 fied. Though it diffi-rs from his description in the usually small leaves, and in the often 

 fewer stamens, I have followed my predecessors in referring it to his /. icosandra. Jack 

 describes the flowers as 5-6-.merous. The pedicels appear to elongate very much us 

 the bud advances, and up to the ripening of the fruit. Ihere are perhaps two varieties, 

 one with peduncles shorter than the leaves, and longer pedicels. 



2. X. cuneata, Mi<j. Fl. Ind. Bat. Siippl i. 484 ; leaves oblong-spathu- 

 late or obovate-oblong obtuse quite entire or crenate narrowed into a very 

 short petiole, cymes peduucled, stamens about 10, capsule turgid |-| by 

 \ in. broadly ovoid.

I retain this species with great doubt, the foliage and flowers appear to be identical 

 with those of/, icosandra, but the capsule is very mych broader for its length. 1 have 

 seen two Sumatran specimens thus named by Miouel himself, of which one alone has 

 these broad capsules ; the other appears to be in this as in every other respect, identical 

 with /. icosandra. Miquel does not describe the capsule, and I hence do not know 

 which he meant to be /. cuneata. 



3. I. khasiana, Hook.f. ; leaves elliptic-lanceolate obtusely acuminate 

 quite entire narrowed into a slender petiole, nerves very oblique, peduncles 

 slender shorter than the leaves, cymes dense-flowered. Hypericinea pedun- 

 culosa, Wall Cat. 4826. 



KHASIA MTS., F. de Silva. 



Similar in habit to /. icosandra, but the leaves are of a totally different shape, much 

 more membranous, and the flowers are twice as large. Leaves 3-4 in., membranous ;
