Potentilla ranunculoides Hamb. & Bonp.; Nestl. Monog. Pot. 
56, of Mexico, belongs also to this group, differing from the North 
American species by its large petals and very broad rounded leaf- 
lets. 
POTENTILLA MULTISECTA (Wats.). 
P. diversifolia multisecta Wats. King’s Rep. 5: 86. 1871. 
This was also included in P. dissecta by Watson. It isa proba- 
bility that it is the original P. dissecta Pursh, the description of 
which fits this, as well as P. Ranunculus Lange, better than the 
plant for which the name is used, viz. P. diversifolia Lehm. 
From this, P. mu/tisecta differs not only in the finely dissected 
leaves, but also in the smaller flowers. The leaves are not truly 
digitate, but the outer leaflets are attached a little lower, as in P. 
decurrens. All are divided into linear divisions. This species there- 
fore connects the Aureae with the Mulujugae, especially with P. 
pinnatisecta and P. millefolia, It ranges from Nevada to Montana 
and Wyoming. 
A small group, nearly related to the Awzreae, especially to 
£. decurrens and P. multisecta, but with the leaves more or less 
tomentulose beneath may be known as the Sudjugae. The leaves 
are at the same time digitate and pinnate, z. ¢., they are digitately 
3-5-foliolate with a pair (in the last sometimes 2 pairs) of smaller 
leaflets further down on the petiole. In this respect they resem- 
ble P. pulchella, from which the Sudjugae differ in the style, which 
is filiform. They are all low and tufted, or cespitose, delicate 
Plants from Colorado, less than 2 dm. high, except the first, which 
Sometimes reaches 3 dm. It approaches in size and habit the 
Gracilis group, 7. ¢., P. gracilis and its varieties as understood by 
Watson. Strangely, all four seem to be undescribed. 
POTENTILLA SUBJUGA N. Sp. 
,, rufted from a perennial root; stems many, I-3 dm. high, 
silky-villous, few-leaved, rather divergently branched above, the 
wer portion covered with the brown scarious lower stipules ; up- 
Per stipules green, ovate, entire. Basal leaves many, digitately 5- 
(seldom 3-) foliolate with an additional pair of smaller leaflets on the 
Petiole, about 1 cm. below the others; leaflets 1-4 cm. long, oblong 
or obovate, deeply incised into oblong rather obtuse segments, 
silky and green above, silky and white-tomentose beneath ; stem-
