poila are saiil not to be stem-clasping, but in B.M. 5355 



they are deserilieil and figured as stem-clasping. 



All the names given below are American trade names, 

 except T. fliiva, Formosana and latifolia. The writer 

 has been tempted to include these, partly because there 

 has been no account 'in English of all the species, but 

 chiefly because they are desirable plants likely to come 

 into cultivation.

fliva, Maxim. Stem dwarf: Ivs. oblong -lanceolate: 

 fls. racemose, yellow, not spotted. Seen by Maximo- 

 wicz in the gardens of Yedo only. 



pildsa, Wall. Stem 2-1 ft. high, very slightly pilose: 

 Ivs. oblong: fls. numerous, loosely corymbose, whitish, 

 with large purple spots ; style half as long as the stig- 

 mas. Himalayas, 5,000-6,000 ft. B.M. 4955 (perianth-

latifolia, Maxim. Stem glabrous, flexuous, 2-3 ft. 

 high: Ivs. broadly oblong or the uppermost ovate: fls. 

 tew in a terminal corymb, whitish, with minute purple 

 spots; style as long as the stigmas. Japan. 



inacT6poda, Miquel. Stem 2-3 ft. high, puberulous 

 above: Ivs. oblong: fls. in a loose'corymb, whitish pur- 

 ple, with minute purple spots: style half as long as the 

 stigmas. Blooms in June and July, according to J. B. 

 Keller. Japan, China. B.M. 6544 (segments broadly 

 ovate, decidedly yellow, spotted red and veined red 

 near tips). -In F.S. 18:1820 is figured a plant with ses- 

 sile Ivs. striated with white, and no fls., which he refers 

 to T. marropoda. This was sent out by Van Houtte as 

 2'. liirsKtii. but it is a glabrous plant and probably lost 

 to cultivation. 



T. grandiflbra, Hort., should be compared with T. hirta, var. 

 iiiKra. It is a name scarcely known to botany. Ellwaiiger& 

 Harry say it has orchid-like, fragrant fls. in Oct. and Nov. 

 (Baker says the genus has no fr.<iKJ-ant fls.) Krelage says that 

 T. grandiliora has white fls. mottled with black. -^ ^ ji_
