 thriving best in a moderate temperature and in a light, fibrous soil 

 mixed with sphagnum." (Siebrecht. )- T. Lindenii=T. Lindeniana, 

 T. mus<itea=Guzmania. T. muscdea, Hort., is probably a Pit- 

 cairnia. P. muscosa. Hook., B.M. 4770, is Piteairnia Beycalema. 

 The name T. muscosa has occurred in the trade, but the plant is 

 unknown to the writer. T. polytrichioides. Mass. Lvs. small, 

 densely clothing an elongated st. : infl. 2 1-fld. : petals pale. S. Amer. 

 R.H. 1912, p. 431. T. splendent Vriesia. T. Wihonii, Wats., has 

 been intro. sparingly to cult., but does not appear to be in the 

 trade. It was discovered in Hernando Co., Fla., in 1887 by W. P. 



Wilson, of the Univ. of Penna.: "St. simple, very short (about 

 1 ain. ) : Ivs. numerous, 1-3 or.4 in. long, gradually narrowed from the 

 clasping base to the long-attenuate apex, channeled above, more or 

 less hoary, with minute appressed, peltate, brown-centered scales: 

 peduncle very slender, recurved, about equaling the Ivs., with 2 

 distinct bracts, probably 1-3-fld. : fls. and caps, not seen." This is 

 Sereno Watson's original description, 1888. See Mn. 2, p. 180, and 

 6, p. 130, for pictures. T. xiphioides, Ker. Lvs. densely scaly: 

 scape very short or wanting: petals white. Argentina. G.W. 6, p.

 iculate, subtended by scarlet bracts: fls. yellow. Costa Rica. B.M.
