B28 THE JOURNAL OF BOTANY 



from Toupinambault, Brasil ; Burser sent a duplicate to Caspar 

 Bauhin, who describes the phmt in his Prodr. 91 (1620) as Solcnmm 

 tri/phi/llum Bvasilianum, saying, "hoc in sylvosis Brasiliae apud 

 Tououpinambaultios copiose reperitur, referente PharmacopnsoGallo, 

 qui una cnm ahis D. Bursero communicavit" ; the sepals are 8 in. 

 long, petals 2 in. Tlie author in his Amoen. cites also Solanmn 

 trlphylliun canadense. Corn, canad. 166. 



Linnseus's fourth citation, Solano coiufener triphylhim Canadense 

 Moris, hist. 3. p. 532, § 13, t. 3, f. 7, is the same plant as Cornuti's, 

 which is moreover cited as a synonym. 



The plant in Linn?eus's herbarium under this name is a specimen 

 of Medeola rirginica L. received from Kalm. 



In the absence of Burser's specimens, we are referred back to 

 Cornuti's figure and description to determine what Linn feus meant 

 by his species ; this is evidently what is generally understood as 

 T. erectnm. 



The specimens show considerable variation in the size and 

 breadth of the leaves, size of the flowers, colour, relative size and 

 breadth of petals, absolute and relative length of stamens and 

 stigmas, and relative length of anther and filament. 



We can distinguish — 



(1) A smaller less robust form with rhombic, shortly acuminate 

 leaves, flowers small to moderate, stamens barely or not much 

 longer than the short recurved stigmas, and filaments three-fifths 

 to four-fifths the length of the anthers. The petals may be white 

 or claret, and are ovate, blunt, and slightly to about one-third 

 longer than the sepals. The stamens are 6-10 mm. long, the 

 stigmas 2-4 mm. 



I have seen specimens from Canada, New York, Vermont, 

 Massachusetts, and Tennessee (Smoky Mts. Finns canadensis 

 region, Rugel). Some of the Tennessee specimens have very 

 small leaves and flowers (sepals 12 mm., petals 14 mm., and 

 stamens 6 mm. long). 



T. penduhim Willd. /. c. must be included here. 



(2) A robust form with large broadly rhombic shortly acuminate 

 leaves, large flowers, anthers more than twice to many times as 

 long as the filaments, and falling short of the tips of the long stout 

 outwardly curving stigmas. The petals may be white or claret ; 

 they are elliptic or ovate, obtuse to subobtuse, and about equal in 

 length to the sepals. The stamens are 1-2 cm. long, the filaments 

 2*5-5 mm., the anthers 8-18 mm.; the connective is generally just 

 prolonged above the anther-cells ; the stigmas from 5 to 10 mm. long. 



We have specimens collected in Canada by Masson (1799-1802) 

 with sepals and petals 4 cm. long, and from several of the North- 

 eastern United States (Ohio, Kentucky, Illinois). 



The specimen which Bauhin had from Burser, purporting to 

 come from Brazil, may belong to this form ; it is described as having 

 leaves 4 in. broad and 5 in. long, "ex rotunditate acuminata," 

 sepals 3 in. long, petals white, 2 in. long by 1 in. broad. 



(3) Var. viridifiorum Hook. Bot. Mag. 3250, nearly allied to 

 (2), but characterized by its rather broadly ovate greenish petals.
