ASARUM GRANDIFLORUM (Michx.) Small. (Homotropa macranthum, 
Shuttl. mss. in dist. Rugel, 1841. Asarum Virginicum, L., var. 
grandiflorum, Michx. ex Duchartre in D.C. Prodr. xv. 426 
(1864)). 
It seems strange that this conspicuous plant should have been 
overlooked for so many years and not received any recognition in 
our text-books. It has been practically unnoticed by botanists 
since Rugel's collection of 1841.* On specimens of that collec- 
tion Shuttleworth based his Æomotropa macranthum. This was 
not Rs but distributed as a manuscript name. 
When Duchart hed the genus for DeCandolle’s Prod- 
romus he m up the name ne -prandi iflorum, apparently from a man- 
uscript name left by Michaux, as he credits the variety to him. 
However, he has made a mistake in referring to the name as being 
published by Michaux in his Fl. Bor. Am. i. 279. 
After meeting with the plant during the last two seasons and 
studying it in the field, we reach the same conclusion as Shuttle- 
worth did, that is, that it is not a variety of A. Virginicum, but a 
good and distinct species. As there is no complete description 
published, the following is appended. 
Perennial, stout, arising from a more or less branched rhizome, 
glabrous ; leaves varying from broadly-ovate-cordate to orbicular- 
cordate, 5-9 cm. long, 4-8 cm. broad, obtuse or acutish, long- 
petioled, mottled or simply green, paler beneath; flowers solitary, 
large, 1.5-4 cm. long, tubular-campanulate, limb not contracted 
but divided into three large, unequal spreading lobes, which are 
mottled with violet on the inside; peduncle 2-2.5 cm. long; 
anthers equally four-ribbed, seed oblique-ovoid, acute, 3.5 mm. 
long, smooth.
