canaliculars recurvis, panicula pyramidali, bracteis ovatis pedicellos subaequantibus, perianthii 

 laciniis ovato-lanceolatis, acuminatis glandulis distinctis. Schult. — Mich. Fl. Am. v. l.t. 22. 

 —Schult. Syst. Veget. v. 7. p. 1559. 



2. Zigadenus commutatus ; radice bulbosa, foliis ligulato-elongatis convoluto-canaliculatis 

 nervoso-striatis, racemo raro simplici pyramidato, scapo subnudo, bracteis longitudine 

 pedicellorum, periantbii late ovatis cum acumine, glandulis confluentibus. Schult. Syst. 

 Veget. v. 7. p. 1560. — Helonias glaberrima. Ker, Bot. Mag. t. 1680. 



Of this there appears to have been only one specimen gathered. The locality from which the specimens 

 figured in the Botanical Magazine were derived, is unknown ; Mr. Ker having merely supposed it to be 

 Virginia and Carolina, from confounding it with Michaux's plant.

1. Juncus Xiphioides ; foliis culmeis ensiformibus enodulosis, panicula supradecomposita, 

 periantbii laciniis lanceolatis acuminatis suba?qualibus capsulam trigono-oblongam acuti- 

 usculam subaaquantibus, testa seminis nucleo conformi. Meyer. — Schult. Syst. v. 7. p. 244. 



Of this, there is only one specimen, but quite agreeing with the character. 



1. Luzula spadicea. Desv. — Juncus spadiceus. All. 



Of this, only a fragment exists in the Collection. The testa is of the same shape as the seed. 



Ord. LI. GRAMINEiE. Juss. 

 1. Vilfa stolonifera, P. B. ?— agrostis stolonifera. Sm. ? 

 Of it there this only part of a specimen. 



1. Phalaris Calif ornica ; panicula subspiciformi oblonga, glumis patentibus concavis 

 ovato-lanceolatis trinervosis, glumellis pubescentibus, rudimentis duobus oppositis glumellidai- 

 formibus pilosis e basi callosa subpedicellatis, vaginis foliorum arctis, ligula oblonga 

 elongata. 



This, as far as regards the panicle and habit of the plant, is intermediate between the true species of 

 Phalaris, and Digraphis of Trinius. In character, it approaches most to the latter, especially by the shape 

 of the rudimentary florets. The panicle is about the size and form of that of Phalaris Canariensis, or Ph. 

 bulbosa, but it is not nearly so compact. 



Ord. LII. FILICES. Juss. 



1. Polypodium Californicum ; frondibus profunde pinnatifidis, laciniis oblongis seu 

 lineari-oblongis obtusis argute serratis, inferioribus basin versus angustatis decurrentibus, 

 venis obliquis parallelis, venulis dichotomis anastomosantibus, soris ovalibus solitariis. — 

 Kaulf. Enum. Fil. p. 1 02. 



The greater breadth of the fronds and of the segments, and the oval sori, readily distinguish this from 

 P. vultjare. 



1. Gymnogramma triangularis ; frondibus triangularibus decompositis, pinnis oppositis 

 adnatis pinnatifidis inferioribus margine exteriori pinnato-pinnatifidis, pinnula infima lineari-
