280 NEW PLANTS, ETC., 



white flowered plant, O. majus, tliought by Hasskarl to be 

 possibly the Ophioxylon album of Gerstan, forms in the stove a 

 small light green shrub with oblong-lanceolate membranous 

 leaves placed in threes or fours, and loose cymes of white flowers. 

 The corolla is nearly three quarters of an inch long, with the lobes 

 of fhe limb half circular. 



It is a stove shrub, growing freely in a mixture of sandy loam 

 and peat ; but requires to be kept in rather a moist atmosphere. 

 It is increased by cuttings put in sand under a bell glass, and 

 plunged ill tiie bark bed. Flowers in April and May. The plant 

 is of little value in a horticultural view, the white flowers being 

 too small to produce a striking effect. It is however of some 

 medical interest, being one of the plants whose roots are be- 

 lieved by Indian practitioners to be a cure for the bite of venom- 

 ous serpents.
