Oxymitra.] flora indica. 145 



ovali-oblongus. Carpella spathulata, stipite late compresso, seaquipollicem longa, 

 inucronata. 



This species differs from A. Javanica in several important points. In that species 

 the ovaries are 8-10, globose, broader than and very distinct from their pedicel, and 

 terminated by a depressed, almost globose style. The abnormal inner anthers of 

 that species are also wanting in the A. Zeylanica^ which, however, agrees in every 

 respect with Cuming's and Lobb's specimens from the Philippines. Cuming's No. 

 496 !, also from Luzon, is not certainly identical with our plant. We have not ex- 

 amined its flowers, but, according to a note by M. Planchon in Herb. Hook., the 

 anthers are different from those of the Java species. The leaves of A. Zeylanica 

 are somewhat like those of A, prinoides, St. Hil. ; but in that species they taper gra- 

 dually, and are not abruptly acuminated. The fruit is also very oblique, and the 

 dorsal margin is bent at a right angle, almost semispathulate, while in A. Zeylanica 

 it is nearly regular in outline, both margins being alike. 



20. OXYMITRA, Blume. 



Polyalthiae § Oxymitra, Bl. Fl. Jav. Anon. 



Sepala 3. Petala 6, biseriatim valvata; exteriora raulto majora, 

 elongata, plana, tenuis ; interiora ovata vel oblonga, conniventia, basi 

 iuterdum angustata. Stamina lineari-oblonga, apice truncato-capitata, 

 antlieranim loculis linearibus dorsalibus discretis. Torus alte couicus 

 vel subtruncatus. Ovaria oblonga, dense strigosa ; ovula in sntura 

 ventral! prope basin 1-2 funiculo elongato adscendentia. Stylus obo- 

 vatus. Carpella monosperma. — Frutices scandentes, pedunculis extra- 

 alaribns uniiloris y nervis foliorum obliquis validis remotiusculis, nervulis 

 crebris subparallelis transversis connexis. 



This genus, one of those united by Blume under Polyalthia, but distinguished as 

 a section under the name we have adopted, appears, so far as our limited materials 

 enable us to judge, a very natural one. The species are all very similar in habit and 

 general appearance, and are especially alike in the peculiar nervation, the numerous 

 cross nerves between the distant principal ones being strongly marked. In the two 

 species of which we have been able to examine the ovaries, we find one ovule rising 

 from very near the base, and supported by a longish funiculus, with the nucleus pro- 

 jecting beyond the exostome ; but Blume describes and figures TJ. ciincifor s as two- 

 ovuled. We have, therefore, here, as well as in Fheanthus, one- and two-oyuled 

 species in the same genus ; and perhaps it will be found that the number varies in 

 the same species, but, from the extreme difficulty of examining the ovaries of these 

 plants after drying, this can only be determined by investigating the recent plant. 

 The genus is in floral characters very close in the natural series to Unona, differing 

 little from the section BasymascJialon, except in number and position of ovules, and 



in the presence of small inner petals. 



In addition to the four described below, Cuming's No. 1896, from the Philippines, 

 and 0. cuneifonnis, Blume, are the only species referable to Oxymitra which have 

 come under our notice.
