ORCHIDS OF LESSER VALUE 



ACACALLIS 



The only member of this small genus to which any reference need 

 be made in this work is Acacallis cyanea^ a dwarf plant from Brazil, 

 and closely allied to the Vandas. It has blue flowers that bear a 

 resemblance to those of a small Odontoglossum. It has a creeping 

 habit of growth, and should be grown on a block of wood or an 

 upright teak raft, with a little peat fibre and sphagnum about its 

 roots. This rare and beautiful little Orchid, often described as 

 Aganisia ccerulea, must be grown in the high temperature and 

 moist atmosphere of a stove. 



ACANTHOPHIPPIUM 



Most members of this genus of terrestrial Orchids are natives 

 of Tropical Asia, and therefore need abundance of heat and 

 moisture during the greater part of the year, but during the 

 Winter water must be withheld, except through the medium of 

 the atmosphere. The erect spikes carry from three to seven fairly 

 large, fleshy flowers, but these are not very effiective. The 

 principal species are A. bicolor, yellow and purple ; A. Curtisii, 

 purple-rose, yellow, and white ; A. javanicum, yellow and purple ; 

 A. STRIATUM, white and red ; and A. sylhetense, creamy white, 

 and purple.
