and Miscellaneous Particulars, 
the peculiar structure of the stamens. The milk of Gymnema lactiferum is used instead of the Vaccine ichor, 
and the leaves are employed in sauces in the room of cream. 
584. Calotropis. From xctXog, beautiful, and tz'-'Tm, to turn, in allusion to the beauty of the flowers, which 
continually turn towards the sun. This is a handsome free-flowering genus. Young cuttings root freely in sand 
under a hand-glass, but not crowded, as, if the leaves are injured, they are very apt to damp and get mouldy. 
585. DischiiUa. From It?, twice, and to split ; but the application is unexplained. Little trailing 
plants with small opposite fleshy leaves. 
586. Xysmalobium. From Iviru-n, a fragment of a thing, and Xo/So?, a division, on account of the minute 
alternate divisions of the corona. The flowers of this genus are very large; those of X. grandiflorum are of 
the size and color of Fritillaria meleagris. 
587. Gompkocarpus. From yo/u^o;, a club, and xct^-ros, fruit. A genus resembling Asclepias in habit, but 
well distinguished by the inflated club-like fruit. 
588. Asclepias. The name of many ancient physicians. It is the Greek name of the jEsculapius of the La- 
tins. This is a genus of tall-growing herbaceous plants, which thrive best in peat or any very light soil. They 
require a good deal of room to show their characters, and are readily propagated by seeds or dividing the roots. A. 
syriaca is very odoriferous, and in Canada, when in flower, charms the traveller, especially when passing through 
woods in the evening. The French there eat the tender shoots in spring as we do asparagus. The natives make a 
sugar of the flowers, gathering them in the morning when they are covered with dew, and collect tJie cotton from 
the pods to fill their beds. On account of the silkiness of this cotton, Parkinson calls the plant Virginjan silk. 
A. nivea has jointed fleshy roots, the juice of which is very effective in bringing away worms. The root
