192 MONAl>ELPHIA DODECANDUIA. HiblSCllS. 



siderable force. Seeds from one to three in each cell, kidney- 

 formed, covered with brown farina. 



This species is immediately to be distingujslied from po- 

 pnlneus by the glands in the axills of the nerves of the leaves, 

 their waved border and long- points, and by the double in- 

 tegument of the capsule; the innermost of which requires 

 force and a sharp knife to open it ; whereas in popnlnens it is 

 single, and can be easily broken by the pressure of the thunib 

 and fino-er. 



This tree will answer better for avenues, parks, &c. than 

 popuhieus, because it is much higher to the branches, conse- 

 quently gives a free circulation to the air. 



When wounded there discharges the some yellow juice as 

 in popuhieus. 



As both these trees want the most essential character, the 

 double calyx oi' Hibiscus, I should imagine they would, with 

 more propriety, form a new genus. 



3. H. iiliacens. Willd. iii. 810. 



Arboreous. Leaves round cordate. Flmcers terminal. 

 Exterior calyx ten-tooihed. Capsules f-horter than the calyx, 

 five-valved, each divisible, though not spontaneously, ten- 

 celled. Seed remform. 



Novella, Rumph. Amb. ii. /. 73, is too bad a figure to be 

 quoted ; yet 1 doubt not but it was intended for this tree, 

 and although our plants are unconnnonly luxuriant, 1 never 

 saw any of the leaves with the least tendency to a lateral 

 lobe. 



A native of the Moluccas. Flowers in the hot season in the 

 Botanic garden, though more or less the whole year round. 



4. H. tortuosus. R. 



Arboreous, with a crooked trunk, and variously bent, dif- 

 fuse branches. Leaves round-cordate, crenulate, hoary un- 

 derneath. Stipules and bractes ovate-lanceolate. Flowers
