PHOLIDOTA. 



Inconspicuous and botanically interesting Orchids, 

 belonging to the tribe Epideudrcte, and natives of India 

 and the Malayan Archipelago, extending as far as Southern 

 China. Lindley bestowed the generic name, which is 

 derived from pholis, a scale, and ous, otis, an ear, and is 

 in allusion to the scaly, ear-like bracts of the spike. It is 

 commonly known as the Rattlesnake Orchid. Flowers 

 small, shortly pedicellate, in terminal racemes ; sepals 

 carinate-concave, erect or spreading ; petals usually 

 smaller, slender, flat ; lip sessile at the base of the column, 

 concave and sub-saccate at the base, three-lobed ; column 

 sometimes very short ; bracts ovate, imbricated, and per- 

 sistent, or narrower and deciduous. Stems creeping, 

 branched, with one- or two-leaved pseudo-bulbs. P. inibri- 

 cata {Hook.) and P. vcntricosa [Rchb. f.) are the two species 

 usually met with in commerce. They require to be treated 

 like Lv caste. 



PHYSOSIPHON. 



Epiphytal Orchids belonging to the tribe Epidendrec^, and 

 of botanical interest only. The name given by Lindley 

 is from physao, to inflate, and siphon, a tube ; referring to 

 the slightly inflated tube of the flowers. The three or 

 four species in cultivation are natives of tropical America, 

 and have the habit of Pkurothallis. Flowers small, in 

 elongated racemes ; sepals connate at the base into an 

 ovoid or urceolate tube, which is three-fid at the apex ; 

 petals fleshy, ovate-cuneate ; lip small, articulated with 

 the base of the column, in form like the other petals ; 

 pollen-masses two, ovoid. These plants should be grown 

 in shallow pans, in a compost consisting of equal portions 

 peat and sphagnum, adding a little leaf-soil and sufficient 

 rough sand or broken potsherds to maintain a porous
