ACTINOPTERIS 



ACTIN6PTEEIS {aJcfin, ray, and pteris: the fronds 

 radiat ely cut ). Syo. , Actiniopteris. Polypodi&cea. 

 Greenhouse ferns from India, resembling miniature fan- 

 pahns. The sori are linear-elongate and submarginal. 

 and covered with indusia. A. radidta. Link, is the only 

 recognized species. l. M. Underwood. 



Ada (a complimentary name). OrcliidAcew ; tribe 

 VdHde(e. A genus of epiphytes containing two species. 

 Petals and sepals slightly spreading from half their 

 length ; labellum parallel with the column and united to 

 its base. Found at high elevations on the Colombian 

 Andes. Useful for the coolhouse, where they may be 

 grown together with Odontoglossums, blooming in no 

 definite season. 



aurantlaca, Lindl. Fig. 32. Pseudobulbs 2-3 in., 

 ovate to ovate-oblong, subcylindrical or slightly com- 

 pressed, tapering toward the summits, bearing 1-3 nar- 

 row leaf -blades 6-12 in. long: petals and sepals narrow, 

 pointed, channeled; labellum half as long as the petals: 

 scape drooping, bearing racemes of cinnabar-red fls. 



L^hmanni, Rolfe. Leaves marbled with gray : label- 

 lum white. — Not much in cultivation. A recent species. 

 Oakes Ames. 



The Adas grow at the altitude of 8,500 ft. To grow 

 them successfully, a house that can be kept very cool in 

 summer is necessary, one having a northern exposure, 

 such a', is constructed for Odontoglossums being best as 

 the two plants are found growing together bhadmg
