CoMMELiNACEiE. —Hexandria Monogynia. 
Dichorisandra ovata. This very superior perennial, herbaceous 
plant is a native of Brazil, but we are unacquainted with the par¬ 
ticulars as to the exact locality in which it is found, or by whom 
originally introduced. It attains a height of from three to four 
feet, has large ovato-lanceolate leaves, which are smooth and 
shining, with parallel longitudinal veins, prominent on the under 
side, bright green above and purple beneath, and clasping the 
stem at the base. The flowers are borne on erect, terminal ra¬ 
cemes : they are composed of three ovate, obtuse sepals, which 
form the calyx, and three obtuse, entire petals, larger than the 
sepals, intense blue; at the base rather paler. It requires the 
temperature of a stove, where, during the period of growth and 
flowering, abundance of both heat and moisture can be supplied; 
and where, at the season of repose, it can be accommodated with 
a rather cool temperature and a fair proportion of drought.—

Barkeria Skinneri , var. major. This fine variety is larger and 
stronger than its species in every respect; the flower-scape is 
nearly two feet long, holding upwards of thirty flowers, of a deep 
reddish-lilac purple, with stripes of bright gold colour down the 
lip. In habit it is much stronger, the foliage longer, and double 
the breadth, apparently less delicate than the species, and in every
