The following descriptions are of plants named in this list, and not de- 

 scribed in Gray's Manual. The range of the species, as given, is that 

 hitherto known and published with the respective descriptions. It will 

 be observed that in each instance it is considerably extended by the 

 localities given above. 



Desmodiuii IijLinoense, Grai/. — Eeserabling I), ranescens in flowers and 

 foliage, and D. r/'gidum in inflorescence and fruit; stem (erect, 3-5 feet) and 

 leaves with short rough pubescence; leaflets (2-4 inches long] ovate-oblong or 

 ovate-lanceolate, obtuse, sub-coriaceous, beneath cmereous, veins and voinlets 

 prominent, strongly reticulated, the lower leaflets nearly equahng the petiole; 

 the persistent stipules and caducous bracts ovate-lanceolate, striate, taper- 

 pointed; racemes simple; pods scarcely over an inch, very shortly stipitate, 

 sinuate on both marijins (deeper below); joints 3-5, oval, not exceeding three 

 lines. — Illinois, in dry ground. Fruc. Ariier. Acad., 1870. 



Scutellaria parvola, Michx., var. mollis. Gray. — Rather more diffuse, 

 softly pubescent throughout, pubescence somewhat viscid ; leaves usually three- 

 fourths of an incli long — Oqnawka, Illinois, on the sandy banks of the Missis- 

 sippi. Proc. Amer. Aivid., F///, 1873. Dr Gray says: " So different in aspect 

 is this plant from the ordinary 8. p/(rvida, that I at tirst took it for 8. Drum- 

 ???fl«f7«<, and then lor a distinct species; but I cannot detect sufficient charac- 

 ters, and there are transitions to the ordinary 8. parvula. 



EcHiNOSPERMUM DEFLExuM, Lelim. — Diffusely branched, a foot or so high; 

 leaves from oblong to lanceolate; racemes lax, loosely paniculate, the slender 

 pedicels recurved or deflexed in fruit; flowers soon sparse, 1-3 lines in diame- 

 ter; nutlets with a triangular mostly naked back (a line long), the margins 

 armed with a close row of flat prickles, their bases often confluent. — Saskatch- 

 ewan and Wiunepeg Valley, Dnunrnond, Bonrgenu; Brit. Columbia, iy^f/^. 

 Siberia to Europe. The American specimens have occasionally some few 

 prickles developed from the rough granulate dorsal face of the nutlets. Gray^s 

 Synop. Fl. N. Amer., 1878.
