POTENTILLA. 



P. concinna (humifusa) is another species poured out upon the 

 ground., with the leaves in fives., and white on the under side. 



P. Corsica is P. rupestris pygmam, q.v. 



P. crassinervia makes a very pretty rock- plant, clad in sticky 

 down, with five-lobed, scalloped leaves, and stems of 6 inches, more or 

 less, with sprays of golden blossom, which are much finer than in 

 P. nivalis, which otherwise in some ways P. crassinervia recalls. 

 though it has five-lobed leaves and a definite aversion for the limestone, 

 to which P. nivalis is more or less partial, while P. era -sterna haunts 

 the high granites of Corsica, and there develops a quite squat peak- 

 form called P. c. viscosa. which makes scabs of stickiness in the topmost 

 cliffs and ridges. 



P. crinita is a golden -flowered American of a foot high or more. 



P. dahurica is a small Siberian bush of a foot and a half or so, in the 

 way of P. fruticosa. but finer and straggly in growth, with twisted 

 sprays and yellowish bloom. 



P. delphinensis is a tall yellow-flowered species of IS inches or 

 more from the Western Alps. 



P. deorum, from the rocks of the Thessalian Olympus, imitates the 

 lovely silvered style of P. apennina, but improves upon it by having 

 showier white bkssoms, of ampler and longer petal, gathered in heads 

 of three or five, on graceful almost bare stems of a few inches that 

 emerge from the silver-sheening tufts of foliage. 



P. effusa is large and yellow and American. 



P. elatior is merely a larger Strawberry in general effect. 



P. eriocarpa lives on the high frontiers of Tibet, at some 14.000 

 feet. It has a very few trefoiled leaves, bright -green, and cut again 

 and again ; and then a number of notably graceful stems that 

 vary from 2 inches to 18, fioppeting finely about, and each spray 

 carrying a single splendid golden flower about an inch and a half 

 acro-s. 



P. Fenzlii is quite microscopic, and with little yellow stars of no 

 value. 



P . form osa . S ee P . nepahns is . 



P. fragiformis calls up the Strawberry again to mind, and is an 

 American species, with 8-inch stems, and sprays of white blossom all 

 through the summer and autumn. 



P. Friedrichseni is a hybrid between P. fruticosa and P. dahurica. 

 The result is the loveliest of neat wee crabbed bushes, with stiff 

 depressed arms, and fine foliage that leads to very little else, for the 

 plant is so pleased with its habit as to think there is no need for it 

 to do anything else. Accordingly not a flower does it usuallv put forth.
