 Calyx pilose. Seeds oblong, cuneated, covered by a reticulated

 Laguna ; it has the leaves usually 4 in a whorl, and very scabrous 

 above. The hairs of the stem are somewhat adpressed, and of 

 a dirty, fulvescent colour, not purplish. Corolla purplish,

Quite entire- leaved Angelonia. PI. erect. 



Cult. These are very pretty plants when in blossom, and are, 

 therefore, well worth cultivating. A mixture of light turfy 

 loam and peat is a good soil for them ; and cuttings strike root 

 readily in the same kind of mould under a hand glass, but as 

 they are liable to rot, air should be frequently given.
