ORCHIDE^. 
ANGR\4:crM ebi'rneum. — Ivory Angrsecum. (Fig. 122.) This Genus was 
first established by Du Petit Thouars, in 1822. It consists as far as is at present 
known, exclusively of plants, native of trees in the islands of Bourbon, Mauriti- 
us, and Madagascar, and of the south-eastern part of the continent of Africa. 
The flowers of the present species are without scent, both the segments of the 
Calyx, (sepals,) and the petals are bright green; the front heart shaped segment,' 
(Labellum,) is of a beautiful shining white, like ivory, hence its specific name. 
Native of the island of Bourbon, where it was found both by Col. Borj' de St. 
Vincent, and M. Du Petit Thouars, growing upon trees. It was also met 
with at St. Marj-'s, Madagascar, by the unfortunate Forbes, by whom the only 
plant, that is known to exist in Enrope, was sent to the Horticultural Society. 
It grows slowly, without manifesting the smallest disposition to branch, or pro- 
vide means of propagation. — Bot. Reg. 
A'cERAS SECUNOIFLO^RA. — One sided Aceras. Flowers of a brownish red, 
small. Introduced from Madeira by the Rev. Mr. Lowe. Culture. — It is a neat 
little plant, requiring the same kind of treatment as Ixias and other Cape bulbs; 
that is to say, to be kept quite dry and quiescent during summer. Under such 
management, Mr. Henderson, at Lord Milton's, succeeds in making it flower 
freely evei7 spring. — Bot. Beg.
