288 PROCEEDINGS OF THE AMERICAN ACADEiMY 



fully as broad as the large palate ; spur subulate, as long as the lower 

 lip, porrect or descending. — Northern Canada and Lake Superior to 

 Texas ; also Tropical American. 



U. JUNCEA, Vahl. Stem racemosely or rather spicately 4-10- 

 flowered, the lower flowers more or less distant : lips of the corolla 

 3 or 4 Hues long, lower in large part consisting of the high-arched 

 palate ; spur slender-subulate, at length deflexed. — U. personata^ 

 Le Conte in Ell. Sk. i. 23, & Ann. Lye. N. Y. i. 77, 78. — N. Car- 

 olina in the low country, through to Texas; also Cuba to Brazil. 

 In both species the obovate upper lip of the corolla may be eillier 

 emarginate or quite entire, and the lower either abruptly short-pointed 

 or truncate-emarginate. 



I proceed to make some notes upon the other drawings which were 

 to illustrate Le Conte's monograph. 



" U. CERATOPHYLLA." A full and good figure of U. injinta, Walt. 



" U. MACKOiiHiZA." Li the figure the spur of the corolla equals 

 the lower lip in length, is contracted between the middle and the base, 

 the apical portion narrow and moderately curved upward, and the apex 

 is emarginate. The outline in the monograph is a correct copy of 

 the outlines of one of the two flowers represented in the drawing. 

 Le Conte's description of it, " conic at the base, linear at the tip," 

 appears to have been made from the figure. If this well corresponded 

 with the American plant, one would not hesitate to agree with him 

 that his U. macrorliiza is quite distiuct from U. vaJgnris, not adopting, 

 however, his strong assertion, " that no stretch of the imagination can 

 find any resemblance between them further than what is seen running 

 through the whole genus." Of course he was wrong in supposing that 

 " the U. vulgaris has not the fi'uit cernuous," as much so as has the 

 American plant. As to the spur in our American plant, the emargina- 

 tion is certainly uncommon ; the tapering is gradual from base to tip ; 

 and it is only in the length and consequent slenderness that the Amer- 

 ican form obviously differs from the P>uropean. No known American 

 specimens have the short and truly conical dependent spur of the old 

 figures, such as those of Schkuhr's Ilandbuch and the original and 

 later editions of the English Botany ; but those of Cosson's Atlas and 

 Reichenbach's Icones Florae Germanicaj answer well for our plant, 

 except that the spur in ours is commonly Cbut not always) longer, yet 

 S'ddom more so, or more curved, than in fig. 7 of Reichenbach's tab. 

 1823 (202). The proportions of the palate to the lamina of the lower 

 lip in U. vulgaris, var. Americana, as well in Le Conte's figure as in 

 our specimens, are rather those of U. neglectn, Lehm., or U. major ^
