flowers in April and May. — Z. Atamasco, Herb., growing in the 

 same region and northward, but in drier localities and blooming 

 several weeks earlier, has thin channelled leaves with acute margins, 

 bright green and shining, 1£ to 2^ lines wide, a loose spathe, the 

 flower with a more slender tube and peduncle, rather broader and 

 more acute segments, and anthers 3 or 4 lines long. The most obvious 

 distinction is found in the foliage. 



Hymenocallis Palmeri. Bulb small (4 or 5 lines thick), nar- 

 rowly oblong, with thick roots : leaves with short sheaths, very narrow, 

 a foot long by 3 lines wide or less : scape slender, 8 or 10 inches high, 

 1 -flowered : spathe-segments 3, narrowly linear : perianth-tube scarcely 

 dilated above, about equalling the narrow (a line wide) segments, 

 which are 3 1 or 4 inches long: crown tubular-funnelform, 15 lines 

 long, the border acuminately lobed between the stamens : filaments 

 a third shorter than the perianth ; anthers greenish : ovary oblong- 

 ovate, 9 lines long. — Biscayan Bay, Florida, Dr. E. Palmer (n. 554, 

 1874). 



Hymenocallis humilis. Bulb twice larger, upon a thick root- 

 stock : leaves with broad sheathing bases, 4 to 6 inches long by 2 lines 

 broad : scape slender, scarcely equalling the leaves, 1 -flowered : spathe- 

 segments 3, greenish, narrowly linear : flowers greenish ; tube scarcely 

 dilated above, 15 lines long, shorter than the narrow segments (2 

 inches long) ; crown broadly funnelform, 8 lines long, truncate be- 

 tween the stamens : filaments a third shorter than the perianth and 

 style : anthers greenish : ovary narrowly oblong, 5 lines long, be- 

 coming an inch long in fruit. — Indian River, Florida ; Dr. E. Palmer 

 (n. 555, 1874). Though our species of this genus cannot be said to 

 be well known, yet it seems to be safe to propose the above as new 

 species, differing so markedly as they do from any previously described. 

 Of the species of Pancratium given in Chapman's Flora, there can be 

 little doubt that neither P. maritimum nor P. nutans will be found 

 within our limits. The original P. Carolinianum of Linnseus (founded 

 on Catesby's figure) was probably Hymenocallis rotata, and all later 

 figures and descriptions of " P. Carolinianum " were based upon the 

 foreign P. maritimum. It is probable that Pancratium, as now under- 

 stood, and Ismene are not represented in our flora. 



Brodlea Howellii. Resembling large forms of B. lactea: 

 stem nearly 2 feet high: flowers larger (9 or 10 lines long and about 

 equalling the pedicels), purplish, turbinate-campanulate, the tube some- 

 what longer than the lobes : outer filaments short and deltoid ; the 

 inner longer, broadly winged the whole length, the wing truncate or
