gigantéa, Wall. ascl. no. 91. b. In addition to the above marks 
of distinction, this differs in habit from all the preceding spe-

of contracted cymes or umbels.

lying on the top of the stigma, 2-lobed : lobes thickish, sub- 
diverging. h. S. Native on the banks of the Irrawaddi.

in small, compact, long-peduncled umbels.

7 C. werpa‘cea; herbaceous, erect, smooth; leaves petio-

which incloses the corona ; segments or petals triangular, spread- 
ing; leaflets of corona shorter than the gynostegium, acute, 
and spreadingly recurved at the base, but tridentate at the apex, 
and lying upon the gynostegium. 2.8. Native of the inte- 
rior parts of Bengal. Padmarka, Jones, asiat. res. 4. p. 267. 
Stems nearly simple. Young shoots green. Leaves pale green, 
paler beneath, furnished with a few bristly glands on the middle 
nerve on the upper side at the base. Peduncles longer than 
the pedicels, mixed with subulate bracteas. Flowers large, 
a mixture of purple, red, and white Very like C. gigantèa. 
Root woody. 
Herbaceous Calotropis. Pl. 2 to 3 feet. 
Cult. All the species of Calótropis bear handsome, large 
flowers, and on that account are worth cultivating in every col- 
lection of stove plants. A mixture of loam, sand, and peat, isa 
good soil for them ; and young cuttings, thinly planted in a pot 
filled with sand, strike root freely under a hand-glass, in heat. 
If care is not taken with them, they are very liable to rot, as the 
least injury causes them to decay.
