94 a LEAFLETS. 
In part III of the Flora Telluriana, page 21. Rafinesque 
succinctly characterizes this type as a genus, and names it ALO- 
ITIS ; and while feeling compelled to agree with him, even as to 
the species which he segregates, I must add the characters of 
several more. 
ALOITIS OCCIDENTALIS. “Amarella occidentalis (Gray), Greene, 
Leafi. i. 53. Calyx-segments usually lanceolate or oblong-lance- 
olate, foliaceous, half the length of the corolla, merely acute, by 
their breadth often nearly or quite closing the sinuses. 
Prairie regions of Iowa, Wisconsin, Minnesota and westward. 
A. MesocHoraY Larger plant than the last, with larger 
foliage and larger flowers but of less branching habit, large 
plants often simple save as to the axillary pedunculiform bran- 
ches: calyx with extremely narrow tube, the unequal segments 
partly linear, partly lanceolate, all setaceously acuminate, the 
longest of notably less than hal! the length of the corolla, the 
sinuses not closed, acute: corolla-lobes with unusually long 
and slender acumination. 
Northern Indiana, also adjacent Michigan and westward to 
„Minois and Iowa. 
A. FOLIOSA. v Habit of the last, with very ample foliage: 
leaves 2} inches long, half as broad; umbellate flower clusters 
all subtended by a pair of well developed leaves like an involucre; 
flowers smaller than in the last; calyx-tube broader, segments 
partly subulate, partly exactly lanceolate, all very acute, the 
longest half as long as the corolla, sinuses open, rather obtuse : 
segments of corolla with short setaceous point. 
Known only from along Vermillion River, northern Ohio; E. 
L. Moseley, 1898. 
A. DIVARICATA. Plant very large, evidently about a yard 
high, widely and almost divaricately branching, copiously flori- 
ferous but the flowers often solitary, or in pairs or threes : calyx 
the smallest in the genus, with very short tube, and not long 
subulate and subulate-lanceolate acute teeth, the whole less than 
one-third the length of the not large corolla, this apparently
