507. Cucurbita maxima (Duch.) leaves cordate, 

 rugose, harshly and densely pubescent on the under side: 

 petioles hispid : flowers campanulate, broad at the base : 

 segments of the calyx often dilated at the apex into an 

 obovate-oblong toothed foliaceous limb : divisions of the 

 corolla recurved : fruit large, roundish, glabrous, toru- 

 lose.— W. and A Prod. I. page 351.

503. Carbiospermum Halicacabum (Linn.) annual : 

 stem, petioles, and leaves, nearly glabrous : leaves biter- 

 nate : leaflets oblong, much acuminated, coarsely cut 

 and serrated : glands of the disk roundish : fruit broad- 

 ly pyriform.— VV. and A. Prod. I. page 109.

509. Visenia umbellata (Blume Glossospermum 

 veluttnum Wall.) The only species of ihe genus, a beau- 

 titul and richly flowering tree of very rapid growth, a na- 

 tive of Java. Leaves cordate, acuminated, serrated, 

 canes erect, from being thickly clothed with appressed 

 silky hairs, corymbs umbellate, flowers very numerous of 

 a p-ile pink or flesh colour. The specimen from which 

 the figure was taken was raised in the Horticultural So- 

 ciety's garden from seed sent by Dr. Wallich.

7 the same cut transversely 



10 cut trans-

510. Polycarpjea spicata. (R. W.) glabrous, stems 

 numerous, slender, diffuse : bearing one or two fascicles 

 of leaves and peduncles : radicle and cauline leaves fas- 

 cicled, glaucous, somewhat succulent, spathulate, oblong 

 obtuse, or somewhat acute : flowers imbricately spiked : 

 spikes several fascicles on the summits of the branches ; 

 sepals scariose, nerved on the back much lunger than the 

 subulate petals : filaments detached at the base forming 

 with the corolla a ring round, the ovary. 



My specimens of this plant were gathered by my col- 

 lectors and the exact locality not ascertained.

fruit — Analysis. 



I A flower and its branches— 2 the sepals spread out 

 showing the corolla and stamens surrounding the ovary 

 but so much shrunk in drying that they give an imperfect 

 idea of their size — 3 stamens — 4 a petal detached— 5 

 a capsule— 6 the same opened showing the seed in situ 

 — 7 a seed— 8 the embryo detached. 



511. A«laia oDERATA(Lour, Adr. de Juss.) leaves 

 pinnate leaflets 5-7 obovate glossy.— D. G\ 



^ The specimen figured is from Ceylon but whether na- 

 tive or introduced is uncertain.

 a sufficiently perfect section to show that part of the
