122 GATES: REVISION OF GENUS POLYGONATUM 
York County, June 3, 1895, S. Williams (no flowers). DISTRICT 
OF CoLUMBIA: Washington, 188-, L. F. Ward (Cal.). KENTUCKY: 
Louisville, 1835, C. W. Shori (flowers 15 mm. long); Bowling 
Green, May 29, 1899, Sadie F. Price. NorTH CAROLINA: locality, 
date, and collector’s name unknown (specimen in the Chapman 
herbarium, type). Missourr: Watson, June 1, 18094, B. F. 
Bush 527. 
One sheet in the Chapman herbarium contains one specimen of 
typical P. biflorum and one of the variety (PLATE, A). Hence no 
doubt they both occur in the same locality. The variety extends 
as far west as Missouri and its flowers vary somewhat in size, the 
leaves also showing some variation in relative width and in 
obtuseness. Indeed I have included a considerable range of forms 
which may ultimately have to be separated. While in the type 
specimen the flowers are small and the leaves scattered on the 
stem, in the Missouri form (PLATE 5, B) the flowers are much 
larger (18 mm.) and the leaves rather crowded on the stem. 
A majority of the specimens cited correspond rather more nearly 
with the latter condition than with the former. 
4. POLYGONATUM CANALICULATUM (Muhl.) Pursh 
Convallaria canaliculata Muhl.; Willdenow, Hort. Berol. 45. 1805. 
Polygonatum canaliculatum Pursh, Fl. Am. Sept. 234. 1814. 
This North American species was described as follows: 
Foliis alternis amplexicaulibus oblongis margine pubescentibus, caule canaliculato, 
pedunculis bifloris axillaribus. Differt a Convallaria pubescenti; foliis oblongis 
glabris margin nein tenuissine pubescentibus, corolla magnitudine et facie 
Convallariae Hist 
C. multiflora Micki. (Fl. Bor. Am. 1: 202. 1805) is given as a 
synonym, from which it may be inferred that the distribution 
“Pennsylvania to Virginia” given by Michaux applies to P. 
canaliculatum. Although the name P. canaliculatum has since 
been used in various senses, yet the pubescent leaf-margins prevent 
its identification with any species at present known. Its exact 
characters should be determined from the original specimens and 
the careful description given by Schultes (Syst. 7: 1670. 1830).
