 short sts. and clustered pseudobulbs which bear 1-2 

 Ivs., grown occasionally in the warmhouse: Ivs. oblong

205

 the lip being blotched and having only seven callous 

 teeth. Peru. S. pdttida, Lindl. St. wanting: Ivs. 2-5,

 glabrous, fls. otherwise as in S. solignus. Austral. 



salignus, R. Br. Moderate-sized tree, glabrous or the 

 infl. minutely pubescent: Ivs. 2^-4 in. long, in the typical 

 form ovate-lanceolate or elliptical, acute, acuminate or 

 rarely obtuse, tapering to a short petiole: peduncles 

 slender, bearing an umbel of 10-20 fls., occasionally up 

 to 30 fls.: fls. greenish white; perianth usually less than

 undivided, oblong-lanceolate and 6-8 in. long, or pin- 

 natifid and over 1 ft. long, with 1-4 oblong lobes on 

 each side, mostly obtuse, quite glabrous, but reddish 

 beneath, penninerved and minutely reticulate: pedun- 

 cles terminal, either 2 or more together in a general 

 umbel or several at some distance forming a short 

 broad raceme, each peduncle 2-4 in. long, bearing an 

 umbel of 12-20 bright red fls. : perianth 1 in. long; ovary

STENOCHL^NA (Greek, narrow and covering). 

 Polypodiaceae. A genus of tropical ferns with long 

 climbing sts. and with usually 1-pinnate Ivs.: fertile 

 Ivs. much reduced in tissue, and bearing the sporangia 

 entirely covering the under sides, sometimes spreading 

 over the margins. The general relationship of the 

 species is with Lomaria, but owing to the way in 

 which the sporangia are borne, they have often been 

 referred to Acrostichum. Culturally they belong with 

 epiphytic plants; they do best on tree fern stems and 

 the like.
