 Platycerium Desv. Polypodiaceae. 8 Afr., Malaya, Austr. (stag-horn 

 ferns), epiph., or on steep rock surfaces. The rhiz. is short and bears 

 alt. 1. of two kinds. The young 1. are protected by hairs. Of the 

 two kinds of 1., the one stands erect (the 'mantle' L), the other is 

 pend., usu. much branched, and bears the sporangia in irreg. areas on 

 its lower surface. Assimilation is chiefly carried on by the pend. 1. 

 Two types of mantle" 1. occur, repres. in P. grande ]. Sm. and P. 

 bifurcatum C. Chr. In the former the base of the 1., which is un- 

 branched, clings closely to the supporting trunk, whilst the upper part 

 spreads out and makes a niche in which humus collects ; in this the 

 roots ramify and absorb food. In the latter the whole of the mantle 

 1. clings to the support, and the only humus-supply is that furnished 

 by the decay of old mantle 1. and perhaps of the tree bark. This sp. 

 grows in great colonies, owing to adv. budding from the roots. In 

 both the bases of the 1. are rather fleshy. Cult. orn.
