DESCRIPTION OF SPECIES. 151 



Lbgtjminosites oonsteictus, sp. noT. 

 PI. XLIV, Fig. 3. 



Leaflets small, thin, entire, lanceolate, rounded at base, constricted 

 near the pointed apex; median nerve straight, scarcely narrowed upward; 

 secondaries opposite or alternate, numerous, thin, camptodrome. 



Tliis leaf is small, quite smooth and entire, 5.5"° long, 2'"° broad below 

 the middle, and resembles in form and size Cassia hyperhorea Heer,^ diifering 

 in having the secondaries more oblique, diverging 40° or 45° from the 

 midrib, less distant, and by the contraction of the leaf belo^v the apex. 



Haliitat: Ellsworth Countv, Kansas. No. Ic of the museum of the 

 University of Kansas; A. Wellington, collector. 



Legxjminosites convolutds, sp. nov. 

 PI. XLIV, Fig. 4. 



Leaf small, partly convolute, subcoriaceous, lanceolate, roi;nded at 

 base and apex; primary nerve thick, nearly equal for its whole length; 

 secondaries thin, numerous, parallel, except the lowest pair, which are at a 

 more acute angle of divergence, camptodrome. 



There is only one fragmentary leaf, j)artly involute, of this species. It 

 is 4*^"" long, 15""° broad near the base, and has eiglit or nine pairs of second- 

 aries diverging 45°, or the lowest pair 35°. All are simple, scarcely curv- 

 ing until quite near to the borders, where they anastomose in simple bows. 

 Tlie a])ex of the leaf is figiu'ed as being rounded, as it is seen in its nearly 

 tubulose upper part. It may have been broken or creased and therefore 

 may be incorrectly represented. Nevertheless, by its basilar form and its 

 nervatioUj the relation of tlie leaf is marked essentially \\\\\\ the Legumi- 

 nosae, for example witli Cass'ia phaseolites Heer^, which has leaves often 

 obtuse at base and apex and an analogous kind of nervation, the median 

 nerve being also generally thick and equal for its whole length. This leaf 

 might also be compared as to its form and size to species of Andromeda, 

 but the lea-ves of this genus have the secondaries generally parallel and 

 more curved in traversing the blade. 



Habitat: Ellsw^orth County, Kansas. No. 704 of the musemn of the 

 University of Kansas; E. P. West, collector.
