and Miscellaneous Particulars. 
shaded gullies in moist woods. The berries are small and succulent, and each contain three hard rugged 
seeds. 
H. Psittacorum bears a great resemblance to Canna : it grows in the wet parts of woods, and on the highest 
mountains. All the species require a strong heat to make them flower freely. 
571. Strelitxia. So named by Sir Joseph Banks, in honor of Charlotte, queen of George III., of thefamily of 
Mecklenburgh Strelitz, and said to have patronized botany. This is a splendid genus, generally kept in 
the stove ; but which. Sweet observes, " will thrive, and flower as well in the greenhouse or conservatory. A 
light sandy loam is the best soil for the species, and they may be increased, but slowly, by suckers. By rubbing 
the pollen on the stigma, when the plants are in bloom, perfect seeds are readily obtained." {Bot. Cult. 111.) 
572. Apocymm. From a.'xo, away, and xvav, a dog ; that is to say, a plant from which dogs must be driven. 
Pliny says his Apocynum is mortal to them. This is a genus of plants of little beauty, but of easy culture in 
any soil. The first species is acrid and blisters the skin. From the stalks of A. cannabinum the Indians of 
North America prepare a substitute for hemp, of which they make twine, bags, fishing-nets and lines, and linen 
for their own wear. 
573. Melodinus. So named by Forster, from /«.-/)Xov, an apple, and ^ivioo, to turn round ; this plant bearing a 
round fruit like an apple, and having a twining stem by which it climbs trees. It is a very smooth shrub, with 
oblong-ovate leaves, and nearly allied to Rauwolfia. Cuttings root readily in sand under a hand-glass. This, 
^^the succeeding genera, as far as No. 592, are all Asclepiadeous plants, and, require nearly similar manage- 
574. Periploca. From m^i'prXey.yi, intertwining, in allusion to the habit of the plants. P. graca is a handsome 
climber, and grows freely in common garden soil, and is propagated by cuttings under a glass, or by layers.
