Cacalia tuberosa is a very distinct and striking plant, 
which one would not take to be a member of the Com- 
posite from its general aspect. ‘The conspicuously winged 
bracts of the involucre give the flower-heads the appear- 
ance of the fruit of some of the Umbellifere. It is a 
plant for wet places in the wild garden or mixed border 
among other big things, as its somewhat coarse habit 
disqualifies it for association with plants of graceful pro- 
portions. It has a hardy constitution, judging from its 
great latitudinal distribution, ranging, as it does, from the 
lake region of Canada southward to Florida and Texas. 
The wild specimens we have seen are all of much smaller 
dimensions than the cultivated ‘one, for which we are 
indebted to W. E. Gumbleton, Esq. 
Descr.—A. robust, perennial herb, glabrous in all parts. 
Stems several, as much as six feet high under cultivation, 
but usually much less than that in a wild state. Leaves 
thick, leathery, ovate or lanceolate, prominently seven- or 
five-ribbed longitudinally, entire or few-toothed; radical 
on very long stalks, including the stalks sometimes two
