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. 



Desmodium Illinoense, Gray. — Resembling D. canescens in flowers and 

 foliage, and D. rigidun in inflorescence and fruit; stem (erect, 3-5 feet) and 

 leaves with short rough pubescence; leaflets (3-4 inches long) ovate-oblong or 

 ovate-lanceolate, obtuse, sub-coriaceous, beneath cinereous, veins and veinlets 

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

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

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

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

 lines. — Illinois, in dry ground. Proc. Amer. Acad., 1870. 



ScuTELL.vRtA parvula., Michx., var. MOLLIS, Gray. — Rather more diS"use, 

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

 fourths of an inch long — Oquawka, Illinois, on the sandy banks of the Missis- 

 sippi. Proc. Amer. Acad., F///, 1873. Dr. Gray says: " So diff"erent in aspect 

 is this plant from the ordinary S. paroida, that I at first took it for 8. Brum- 

 '/?w/ifZii, and then lor a distinct species; but I cannot detect sufficient charac- 

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



EcHiNOSPERMU-M DEFLExuM, Lchm. — DiflTusely 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 Iriangular mostly naked back (a line long), the margins 

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

 ewan and Wionepeg Valley, Diummond, Boiirfjeau; Brit. Columbia, Lyall. 

 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. A?ner., 1878. 



CORRECTIONS. 



Amarantus Blitum (No. 668), of "Flora of Iowa,'' is A. blitoides.
