 numerous, aggregate, shorter than the petioles. O- S. Native 

 of Mexico on the mountains. 



Heart-leaved Ayenia. Fl. June, July. PI. 1 foot. 



Cult . The species of Ayenia are of easy culture ; they suc- 

 ceed best in a rich loamy soil. Cuttings of the shrubby kinds 

 root freely in sand, under a hand-glass, in a moist heat. The 

 seeds of A. cordifblia requires to be sown on a hot-bed, and 

 when the plants are of sufficient size they may be planted out in 

 the open border in a sheltered situation. None of the species 

 are worth cultivating, except in general collections.

 of the botanic garden in Batavia). Lin. gen. no. 1024. Gaert.

 p. 313. D. C.prod. 1. p. 488. 



LIN. SYST. Monadelphia, Polyandria. Calyx 5-parted (f. 

 89. a.). Petals 5, (f. 89. e.) one of which is longer than the 

 rest and cut at the apex (f. 89. 6.). Filaments of stamens 

 monadelphous at the base (f. 89. d.), divided into 5 bundles at 

 the top (f. 89. A.), each bundle bearing 3 2-lobed anthers on 

 the back (f. 89. 1.), opposite the petals. Ovary stipitate. Car- 

 pels 5 (f. 89. g.), constantly connected together, each contain- 

 ing 5-ovulse. Style 1. Stigma somewhat crenate. Capsule 

 inflated, turbinate, 5-angled, 5-celled, 5-seeded(f. 89. g.). Seeds 

 roundish. Cotyledons spirally twisted about the plumule. 



1 K. HO'SPITA (Lin. spec. 1365.) FIG. 89. 



f? . S. Native of the Molucca Is- 

 lands. Humph, amb. 3. p. 113. 

 Cav. diss. 5. p. 18. t. 146. This 

 is a smooth tree, with broad, cor- 

 date, acuminate, entire leaves, bear- 

 ing divaricate racemes of small, 

 pink flowers, so as to form a ter- 

 minal panicle. Rumphius ob- 

 serves that the leaves when bruised 

 have a smell like violets, especially 

 the young ones. 



We have seen this plant in Tri- 

 nidad, where it appears to be her- 

 baceous, about 6 or 8 feet high, 

 with many stems rising from the 

 root. 



Stranger Kleinhovia. Fl. July, Sept. Clt. 1800. Tr. 20ft. 



Cult. This tree will grow well in any light rich soil, and 

 cuttings will root freely in sand under a hand-glass, in heat.

 the petals, sometimes 10, alternately sterile and fertile. Anthers 

 incumbent, with contiguous lobes. Ovary 3-5-celled ; cells con- 

 taining from 2 to 8-ovulse. Carpels 5, 2-valved, usually closely 

 connate into a single fruct, but sometimes somewhat free. Seeds 

 strophiolate at the base. Albumen fleshy. Embryo straight.

 toothed. Flowers yellowish from tomentum. 



Broad-leaved Seringia. Fl. April, July. Clt. 1802. Shrub 

 4 to 5 feet. 



Cult. This shrub will thrive well in a mixture of sand, 

 loam, and peat, and young cuttings planted in the same kind of 

 soil under a hand-glass will root readily, or it may be increased 

 by seeds, which occasionally ripen in this country. 



X. LASIOPE'TALUM (from \aytoy, lasios, woolly, and 

 vtraXov, petalon, a petal ; in allusion to the calyx being woolly.)
