320 RYDBERG: NOTES ON ROSACEAE 
Alchemilla pratensis F. W. Smith and the three succeeding 
species are segregated from A. vulgaris L. A. pratensis has 
usually been known here under the name A. vulgaris and has 
become naturalized from Nova Scotia to Massachusetts. 
Alchemilla Wichurae Buser has been collected only in East 
Greenland. 
Alchemilla glomerulans Buser and A. filicaulis Buser range on 
this side of the Atlantic from Greenland to Labrador, and the 
latter has been collected also on Newfoundland. 
APHANES 
See remarks under Alchemilla. The true Aphanes arvensis L. 
has been collected in America in Nova Scotia, evidently there an 
introduced plant. The American plants, included in it or con- 
fused with it, have much smaller flowers, the hypanthium being 
‘ only I mm. instead of nearly 2mm.long. They were distinguished 
in the North American Flora as four species, differing in minor 
characters. 
A phanes australis Rydb. includes all specimens collected in the 
southeastern United States. It differs from those on the Pacific 
coast in the short ovate sepals, connivent in fruit. In the western 
species the sepals are lanceolate to ovate-lanceolate and ascending 
in fruit. 
Aphanes macrosepala Rydb. differs in the elongated sepals, 
nearly as long as the densely pilose hypanthium. 
A phanes occidentalis (Nutt.) Rydb. and A. cuneifolia (Nutt.) 
Rydb. have short sepals and puberulent or glabrous hypanthium. 
They differ from each other in the form of the leaves. 
LACHEMILLA 
See remarks under Alchemilla. 
Lachemilla orbiculata (R. & P.) Rydb. and L. venusta (Cham. & 
Schlecht.) Rydb. belong to a group in habit and leaf-form approach- 
ing the genus Alchemilla, but the plants are sarmentose. Both 
Alchemilla orbiculata R. & P. and A. pectinata HBK. have been 
recorded for Mexico and Central America. It is evident that the 
specimens labeled as either of the two constitute but one species- 
A closer examination of literature and specimens has revealed
