XIII. BRYOPHY'LLUM (from /3pvw, bryo, to sprout, and

LIN. SYST. Octandria, Tetragynia. Calyx inflated, bladdery 

 before flowering, hardly 4-cleft to the middle ; lobes 4, valvate. 

 Corolla gamopetalous, hypogynous, having a long cylindrical 

 tube, which is bluntly tetragonal at the base ; and the lobes of 

 the limb triangular and acute. Stamens 8, adnate to the base of 

 the tube. Glands 4, oblong. A fleshy, erect, branched, gla- 

 brous shrub. Leaves opposite, thick, petiolate ; some impari-pin-

LIN. SYST. Decdndria, Pentagynia. Calyx 5-parted, much 

 shorter than the tube of the corolla. Corolla gamopetalous ; 

 tube ovate-cylindrical ; limb 5-lobed, spreadingly reflexed or 

 revolute ; lobes obtuse. Stamens 10, adnate to the base of the 

 tube of the corolla : the upper part free, exserted or almost in- 

 closed. Scales oval. Carpels 5, continuous, with the styles, 

 which are subulate. Fleshy shrubs, native of the Cape of Good 

 Hope. Leaves usually scattered. Flowers loose, panicled, pur- 

 plish or orange-coloured. This genus has been divided into 

 sections from the form of the corolla by the Prince Salm-Dyck, 

 but the corolla being unknown in a great many of the species we 

 cannot follow these divisions.
