GATES: REVISION OF GENUS POLYGONATUM 121 
ward to New Brunswick and westward to Kansas and Texas. 
The precise characters of Walter’s P. biflorum are difficult of 
determination. Farwell (J. c., pl. 15, A) published a figure of 
what he believed to be the type of the species, from a specimen 
collected in Franklin, New Jersey, by H. H. Rusby. I have 
examined specimens the exact counterpart of this. It is a fairly 
constant form and I have described it below as P. biflorum 
hebetifolium. It cannot represent Walter’s type because that 
calls for a three-nerved leaf. 
What I believe to be the type of Walter’s Convallaria biflora 
is represented by a suite of six sheets of specimens, all very 
uniform, from the Chapman herbarium in the herbarium of the 
Missouri Botanical Garden. Unfortunately these are without 
locality, but they doubtless came from somewhere in the south- 
eastern states, probably North Carolina. One of the sheets is 
represented in PLATE 4, B, and a description of the specimens 
follows: 
Plant glabrous, 2-5 dm. high, naked portion of stem usually 
shorter than leafy portion. Leavesseven to ten, secund, narrowly 
elliptic-lanceolate, tapering gradually to a long, narrow point, more 
acute than in any other American Polygonatum, 7-12 cm. long, 8-17 
mm. wide, with three to seven more or less prominent nerves, 
tapering gradually toa semiamplexicaul or sessile base. Peduncles 
slender (less than 0.5 mm. in diameter) 2-3 cm. in length, bearing 
one or two flowers on short pedicels 4-6 mm. in length. Flowers 
yellowish, about 2 cm. long and 3-5 mm. in diameter. 
A specimen collected by C. W. Eisenhower at Conewago Creek, 
Pennsylvania, in May, 1898, agrees with the type except that it 
has somewhat broader leaves (15-21 mm. wide). 
’3a. Polygonatum biflorum hebetifolium var. nov. 
A specie differt foliis latioribus et obtusioribus (7—10 cm. longis, 
13-26 mm. latis), sine nervis manifestis aut solum nervo medio - 
indicato; floribus minoribus, albidis (7-15 mm. longis), frequenter 
binis, pedicellis usque ad 1 cm. longis.
