94 LEAFLETS. 



In part III of the Flora Telluriana, page 21, Eafinestjttfe 

 succinctly characterizes this type as a genus, and names it Alo- 

 ITIS ; and while fis'sling compelled to agree with him, even as to 

 the species which he segregates, I must add the characters of 

 several more. 



Aloij:is ocojDEiVTALis. Amarella occidentalts (Gray), Greene^ 

 Leafl. 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. MESOCHOKA. 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 half 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 

 Illinois and Iowa. 



A. FOLIOSA. Habit of the last, with very ample foliage : 

 leaves 2 J 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. DIVAEICATA. 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
