a somewhat moist sandy loam. The single sorts may be 
increased freely by seeds; the double forms must be 
propagated by careful divisions of the roots, or by cut- 
tings. The three species described below are hardy.

A genus containing about eight species of ornamental 
aquatic perennial herbs, one of which is tropical African, 
and all the rest American. Flowers blue or white, small, 
produced from a spathe in the axil of a sheathing leaf- 
stalk; perianth salver-shaped, with a long, slender tube, 
and a spreading, six-lobed limb. Leaves roundish, long- 
stalked or linear, H. limosa may be grown by the sides 
of a pond or rivulet. The remainder require the same 
treatment as other tender aquatics.

comprising about four species of erect hardy herbs, natives 
of Japan, Formosa, or Mandschuria ; closely allied to Aster. 
Flower-heads rather large or medium, loosely and irregu-

corolla rays white or bluish. Leaves alternate, entire or

eighty species of ornamental stove shrubs, rarely climbing, 
natives of tropical, or rarely extra-tropical, South America, 
and a few Western tropical African. Flowers small, very 
often paniculate or racemose. Leaves opposite, and, 
for the most part, entire, usually glandular beneath ; 
petioles short; stipules inconspicuous. The two species 
described below are stove climbers, closely allied to 
Banisteria (which see for cultivation),

species being an elegant stove palm, with a graceful 
spreading habit, and remarkable for the length of the 
tapered segments of its pinnate fronds. It thrives in 
rich sandy loam and leaf mould, and may be increased 
by imported seeds.

genus containing four species of annual or pei a 
herbs, natives of Mexico. Flowers pedunculate, in ter-

house or half-hardy plant. For culture, see half- 
hardy species of Lobelia.
