Cult. Diosma 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. Pentdndria, Monogynia. Calyx 5-parted. Disk 

 adnate to the base of the calyx, witli 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

 petals and inserted in the margin of the disk, or almost wanting, 

 the 5 fertile ones are longest ; anthers ovate, each furnished with 

 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,
