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 24 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 PAatMmERI. 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} 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). 
HyYMENOCALLIS 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. maritiémum nor P. nutans will be found 
within our limits. The original P. Carolinianum of Linneus (founded 
on Catesby’s figure) was probably Hymenoeallis rotata, and all later 
figures and descriptions of “ P. Carolinianum” were based upon the 
foreign P. maritimum. It is probable that Paneratium, as now under- 
stood, and /smene are not represented in our flora. 
Bropi#za Howerrtu. 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
