The name used by Eaton seems to 'have been overlooked alto gether. It may be claimed that the name given was only a mis print for P. leucaphylla, the original name, which, however, is.ante dated by P. lencophylla Pallas, a synonym of P. nivea. The name P. leneophylla, which means woolly-leaved, a very appropriate name, is not only found in the fifth edition of Eaton's Manual, but,also in the sixth and seventh editions and in Eaton & Wright's North reference to any of the editions of Eaton's Manual and gives.Eaton •Sz Wright as a reference under P. which does not ap
pear there. The Kew Index has also omitted P. leneophylla, which should take the place of P. flippiana, being a year older, if it were not for the fact that it very likely is to be explained as a misprint. P. Hippiana is sometimes very 'hard to distinguish from P. effusa, and the two seem to grade into each other. P. Hippiana is, however, as a rule larger, silky as well as tomentose ; the branches are more erect and the bractlets nearly equalling the acute sepals. The species grows on the plains and the foot hills of the Rockies, but generally in richer soil than P. effnsa. It, extends from New Mexico and Arizona to Minnesota and Saskatchewan.
