GENERAL NOTES. 
BOTANY.! 
Scuanouirion; APPENDIX. — About the time when my little ar 
ticle on Schenolirion, for our July number, was issued, a valued Califor- 
nian correspondent, Mrs. R. M. Austin, rediscovered the doubtful species 
referred to, namely, S. album of Durand, and sent me specimens which 
have just come to hand. Pratten’s specimen, the only one before known, 
T have not seen 
Plantes, 
and the specimens (now complete, except as to the fruit 
erence of the plant to his genus Schanolirion. Neverthe 
somewhat from the Atlantic species in the particulars mentioned by E 
Torrey, and especially in the texture of the dried perianth, which x 
scarious, in the manner of Allium. Moreover, only its outer diviso 
answer to the description as to the three “almost confluent nerves, zi 
three inner divisions being strictly one-nerved. Besides, the ore n 
short-stipitate. The ovules in this and the original species of Miche? 
are geminate and ascending, not “horizontal.” The diagnosis of 
fourth species may accordingly be expressed as follows : — 
S. atBum Durand. Leaves rather flaccid; flowers very ™¥ 
e bracts or 
merous 
the 
perianth: the latter bright, white, scarious when dry ; the divisions 
less, except the midrib, which is triple in the three outer, 
the inner: filaments subulate, decidedly perigynous: ovary §
