Cult. Didsma is a genus of beautiful heath-like shrubs; 
they will thrive best in a mixture of peat and sand, with the 
addition of a little turfy loaf; and youngish cuttings, planted in 
a pot of sand, and a bell-glass placed over them, will strike 
root freely without heat.

Lin. syst. Penténdria, Monogynia. Calyx 5-parted. Disk 
adnate to the base of the calyx, with a free, short margin, which 
is somewhat 5-crenate. Petals 5, a little longer than the calyx, 
hardly unguiculate, transversely bearded in the middle on the 
inside, Stamens 5, opposite the segments of the calyx, and 
shorter than them; anthers roundish, each furnished at the 
apex with a minute, rather globose gland. Style shorter than 
the stamens, erect, quite smooth, dilated at the apex into a capi- 
tate stigma. Capsule of 5 joined carpels, each furnished with 
a little horn at the apex on the outside.—A shrub with scattered, 
lanceolate, keeled leaves, with 2 rows of glands on the keel, and 
serrulated, scabrous, ciliated margins, without dots. Flowers 
white, glomerate at the tops of the branches ; peduncles very 
short, each furnished with 2 opposite bracteas. This genus 
differs from Acmadenia, in the sterile filaments being sometimes 
almost wanting.

margin. Petals 5, with long claws; claws bearded on the 
Inside. Filaments 10, enclosed, the 5 sterile ones opposite the 
petals and inserted in the margin of the disk, or almost wanting,

a conical gland at the apex. Style shorter than the filaments, 
dilated at the apex into a capitate, obscurely 5-furrowed stigma. 
Capsules of 5 compressed carpels, each bearing a horn at the 
apex on the outside.—Small, heath-like shrubs, with opposite, 
thickish, keeled, and hence somewhat trigonal leaves, which are 
imbricated in 4 rows and dotted beneath. Flowers white or red,
