334 THE JOUKNAL OF BOTANY 



We have a good series of specimens collected by Rugel in North 

 Carolina, which show considerable variation in the size of the 

 flower. 



Watson (/. c.) considers T. nervosum Ell. as identical with 

 T. Catesbcei Ell., and from Elliott's description this may well be 

 the case. There is in Herb. Kew. a specimen from Elliott labelled 

 " T. nervosum nobis," which, I think, is not T, Catesbcei. It is a 

 poor specimen with a slender stem 7*5 cm. long, rather narrowly 

 ovate shortly-stalked leaves 5-5-5 cm. long by 2-5 cm. broad, and a 

 flower on an ascending peduncle 11 mm. long, with narrow sepals 

 16 mm. long, and larger (badly preserved) petals ; there is but one 

 flower, and the stamens are almost and the pistil quite concealed by 

 the perianth-leaves ; the anthers are apparently straight, and longer 

 than the sligmas. It may perhaps be T. erijthrocarpum Mich. 



15. T. afiine, sp. no v. Herba caule elato glabro, foliis obovato- 

 rhomboideis subsessilibus, apice breviter acuminatis ; flore pedun- 

 culato e foliorum medio cernuo ; sepalis patentibus oblongo-lanceo- 

 latis, abrupte subacutis ; petalis sepala paullo excedentibus ad apicem 

 et basin angustatis ; antheris liuearibus quam filamenta tenuia vix 

 duplo longioribus, stigmata paullo excedentibus ; ovario subgloboso 

 sex-angulato, stigmatibus subelongatis apice recurvatis, in stylum 

 breve basi coalitis. 



Ehizome absent, stem over 30 cm. long, reaching 3*5 mm. 

 greatest diameter in the lower part. Leaves 10-11 cm. long by 

 8-8-5 cm. broad. Peduncle 2-5 cm. long, Sepals 2 cm. long by 

 8-9 mm. broad ; petals 3 cm. long by 13 mm. broad, colourless in 

 the specimen ; filaments about 4 mm. long, anthers about 7 mm. ; 

 ovary barely 5 mm. long, style 1 mm., stigmas 5 mm. Staminal 

 filaments colourless, anthers and pistil purple. 



Resembles T. Catesbcei in having a definite style, but differs in 

 its broader sepals, smaller not undulate petals, shorter stamens, 

 and leaves broader above the middle. The size and habit of leaf 

 and flower recall T. ceniuum, from which, however, it is at once 

 distinguished by its longer stamens exceeding the stigmas, and the 

 union of the latter at the base.

10. T. pusiLLUM Mich. Fl. Amer. i. 215 (1803); Watson, ?.c. 275. 



T. pumilum Pursh, Fl. Amer. Sept. i. 245 (1814). 



Watson places this next to T. stijlosum Nutt. as a doubtful species, 

 known only from the description. Michaux's plant is represented by 

 a single specimen in his herbarium, now at Paris. The locality 

 which he cites is " Pine-woods of Lower Carolina." We have in 

 the National Herbarium, in herb. Gronovius, Clayton's Virginia 

 plant no. 536 (Gronov. Fl. Virgin. 1743, p. 157), on which Asa 

 Gray has written " cf. T. pumilum Mich." A similar plant occurs 

 in Linngeus's herbarium, written up by Linn^us ''T. sessile'' (a 

 species of which there is no representative), and on the back of his 

 sheet in the same hand " Trillium 1 j Tradescantiae affinis, fl. odorato 

 unico tripetalo, radice tuberosa Clayt.," that is to say, an abbrevi- 

 ation of the description of Clayton's plant. Sir J. E. Smith has 

 written " prob. T. j^usillum Mich.," and in IRees's EncyclopcBdia
