120 GATES: REVISION OF GENUS POLYGONATUM 
MASSACHUSETTS: Purgatory Swamp, Westwood, May 14, 
1904, A. H. Moore (Cal. 158495). The specimen here cited and 
photographed (PLATE 4, A) agrees with Farwell’s description 
except that the peduncles are mostly two-flowered. This form 
is decidedly smaller and more slender than var. cuneatum, but 
may perhaps be connected with it by intermediates. The dimen- 
sions of the specimens studied are as follows: stem 1.5-2.5 mm. 
in diameter, rootstock 4—5 mm. in diameter, leaves pubescent and 
glaucous below, elliptical, 4.5-6 cm. Jong, 14-22 mm. wide. 
2. POLYGONATUM HIRTUM (Bosc) Pursh 
Convallaria hirta Bosc; Poiret, Encyc. 4: 369. 1796. 
Polygonatum hirtum Pursh, Fl. Am. Sept. 234. 1814. 
This species is unknown at the present time, but there should 
be no difficulty in identifying it from Poiret’s description and the 
specimens in Paris. It is evidently most nearly related to P. 
pubescens, with which it agrees in having pubescence along the 
nerves on the ventral surface of the leaves, but from which it 
- differs in that the stem and peduncles are also pubescent. The 
leaves are described as sessile, nearly amplexicaul, oval, large, 
ending in a long, obtuse point. The peduncles are said to be an 
inch long and two- or three-flowered. The size of the flowers can 
only be determined by examination of the specimens at the 
Museum d’Histoire Naturelle in Paris. Crevecoeur brought the 
species from North America to the Jardin des Plantes in 1789. 
3. POLYGONATUM BIFLORUM (Walt.) Ell. 
Convallaria biflora Walt. Fl. Car. 122. 1788. 
Polygonatum angustifolium Pursh, Fl. Am. Sept. 234. 1814. 
Polygonatum biflorum Ell. Bot. S. C. & Ga. 1: 393. 1817. 
Convallaria angustifolia Schult. Syst. '7: 301. 1829. 
Polygonatum multiflorum B americanum Hook. Fl. Bor. Am. 2: 
176. 1840 (in part). 
Carolina to Pennsylvania. 
This species occurs on the Atlantic coast, but its full range is at 
present unknown. Since the second edition of Gray’s Manual, 
in which P. pubescens and other forms were merged with it, P. 
biflorum has been an inclusive species, supposed to range north-
