Ada auranliaca is a coolhouse orchid and will thrive 

 well with tlio odontti§;lossiiiiis where they are eiihi- 

 vated; the bristlit oningt^eolond hlooins add interest to 

 the coUei-tion when in sprinti display. The culture is

 lip and column. (Plant X l-z) 



simple if potted in peat fiber with plenty of drainage; 

 sphagnum mav be added if it can be made to grow 

 but if not it becomes sour and inert, and is best lett out 

 of the material for cool orchids. Adas are evergreen 

 and should never be dried at the roots as they grow in 

 boeg^• soil at 8,.'50O feet elevation in Colombia. I here 

 is another species, .1. Lthmnnnii, which is very distinct, 

 but since the unfortunate death of Consul Lehmann, 

 it seems never to have been reintroduced to cultivation.

ADAM ARA (from a personal name). Orchiddcex . A 

 name proposed by the Royal Horticultural S()Ciely of 

 I^jndon to cover the mult igeneric hybrids of the genera 

 Bra88avola,Cattleya, Epidendrum and La^ha, the name 

 Linneara being proposed for combinations of certain 

 other orchid genera. The International Congres.s ot 

 Horticulture hold at Brussels in 1010 adopted Un- 

 nenra for four genera named above, and legislated that 

 "multigeneric hybrids receive a conventional generic 

 name preferably that of a distinguished man, to which 

 is abided the termination nrn. A distinct generic name 

 will be formed for each different combination of genera.

 Fla., where fr. is 9-12 in. long, and called "monkey's 

 bread." Figs. 118 and 119 are from specimens growing 

 in the American tropics. The fl. opens wide, some- 

 thing like a spreatling hibiscus, and the petals soon roll 

 back and wither, as shown in Fig. 119. The tree is very 

 thick-ljoled, and the wood is soft and light. The tree 

 is supposed to attain to vast age. The fr. of the baobab 

 is a gourd-like structure, of which the pulp is said some- 

 times to be eaten and the juice used for the making 

 of a beverage. The bark produces a very strong fiber.
