Michauxii 



This genus was indicated 



H 



in the Journal of the Academy of Philadelphia (n. ser. vol. 2.) It is much, more nearly related 

 to Ornithogalum than to Phalangium. 



Smilacina stellata, Desf. in Ann. Mm. 9, p. 51. Near the Copper Mines, Kew Mexico ; 

 Bigelow. Moist places near Montereyj California, April ; Parry. The raceme is looser, and 

 the pedicels considerably longer than in the eastern plants. 



Smilacina bacemosa, Desf. I. c. Mountains on the Mimbres, April — May ; Bigeloio^ Thurher. 

 California ; Parry. The branches of the panicle are shorter and fewer-flowered, both in 

 the California specimens and in those of New Mexico, than in the plant of the Eastern States. 



PoLYGONATUM BiFLORUM, £IL Sk. 1, p. 393? Copper Mines, New Mexico, June; Bigeloio. 

 (No. 1917, Wright.) Whole plant quite smooth. Stem about a foot and a half high. Leaves 

 narrowly oblong, glaucous underneath. Peduncles 2-flowered, Filaments very slightly rough,

Sandy hills and plains. New 



Mexico, Western Texas and Chihuahua, May— August. (No. 910 and 911, Wright] No 

 of Fendler's New Mexican collection.) 



SCHGENOLIEION, Kov. Gen. 



Perianthium corollaceum, 6-phyllum, persistens ; sepala 3-5-nervia, patentia. Stamina 6, 

 im^ bagi sepalorum inserta ; filamenta subulata basi complanata ; antherae oblong^e^ utrinque 

 bifidfej introrsae. Ovarium liberum^ ovali-globosum, subsessile, 3-loculare; ovula in loculis 2, 

 collateralia, horizohtalia, anatropa; stylus filiformis, rectus ; stigma minutum, 3-lobum. Capsula 

 globoso-obovata, 3-loba; loculis 1-2-spermis. Semina subglobosa nigra nitida. — Herbfe pe- 

 rennes; rhizomate bulboso-tuberosa; foliis subradicalibus angusto-linearibus subcanaliculatis; 

 scapo gracili; floribus albis in racemis simplicibus vel laxe paniculatis; pedicellis juxta florem 

 articulatis basi bracteatis,

ScHCENOLiRiON MiCHAUXli : pedicellis bracteis 2-4-plo longioribus; sepalis ovatis; nervis sub- 

 distantibus. — Phalangium croceum^ Michx. FL 1, p. 196. Ornithogalum? croceum^ Ell. Sic. 



l^p. 397; Kunthy Enum. 4^jp> 371. 0. Texanum^ Scheele in Linnmay p. 146. Moist places on 



the Colorado of Texas^ Marcb — April ; Wright. Also found on the Eed River of Louisiana, by 



Dr. Hale, and in East Plorida by Mr. Bucldey and Dr. Chapman. Rhizoma oblong or some- ,p, 



times elongated, about as thick as tlie little finger, crowned with a scaly bud or bulb. Leaves 



1-1^ foot long, narrowly linear^ glabrous, somewhat channelled above, and rounded underneath. 



Scape 1^-3 feet high, terete, slender, simple, or with a few branches above. Racemes 8-25-flow- 



ered, the pedicels 5-8-lines long, somewhat spreading, witb short bracts at the base. Perianth, 



when expanded, 4-5 lines in diameter, spreading, white, the 3 exterior sepals greenish externally 



along the middle. Stamens a little shorter than the perianth ; filaments white. Capsule coriaceous, 



somewhat truncate^ with 3 rounded lobes ; cells 1-2-seeded, one or two of them abortive. Seeds 



globose-obovate, black and shining. Embryo straight In the axis of fleshy albumen. The 



flowers of this species are yellowish when dry', a circumstance which doubtless gave rise to the 



specific name of Michaux, but which had best be superseded, as it may lead to error. S. album, 



Burand^ differs in its pedicels being much shorter than the subulate bracts ; in the oval sepals 



which are narrowed towards the base, and in the almost confluent nerves. The perianth is also
