for some of the confusion into which we have fallen, : pe 
Musci Bor. Am. is a mixed specimen, distributed as : ~~ 
Hpe. Hab. in Ohio,” but containing both L. sadieeae a - pi 
dum. The specimens from Lancaster, Ohio, in Su ivan i 
herbarium, however, are all the northern species agreeing ie 
European specimens, and not L. minus, Hpe. . oo . : 
fusion has been caused by Lesquereux and James’ Manual, 2 : 
91, where L. minus, Hampe, is cited asa synonymn of . ee 
Sulliv., which it is not, and the true ZL. mznus, Hpe. is desc Be 
as L. sediforme, Mueller. Again authentic specimens ei 
to Dr. Carl Mueller and he says “Leucobryum minus, Hpe. 2 
non est meam L. sediforme, Syn. Musc. differentiam pense 
utramque perfecte descripsit. Huosque antam insula Hepa? 
accepi.” That is, L. sediforme is not our Florida 4 Pe 
Authentic specimens from Florida were also sent to Nee 
Mitten, who says in part “I have Drummond’s 46, D. 4 a 2 
var. albidum, from New Orleans, and a small specimen: Ae 
James, marked by him ‘Z. sediforme ? Florida, Palmer, a 
another small specimen from Florida collected by LeCante oe 
these have the short, wide, appressed foliage so evident in He: 
specimen. Ihave also a scrap of Sullivant No. 99. ti Be 
Hpe., Ohio, with longer, narrower, more spreading leaves. Ze 
ing on Dr. Mitten’s suggestion I sent to Paris authentic Xe 
mens of L. minus, Hpe. in this case a portion of ALES s Mu a 
Appalachiani, No. 477, for comparison with Michaux s sie 
D. glaucum pumilum, at the Jardin des Plantes. M. gee : 
kindly sent me a fruiting plant, and Mr. A. F. Foerste on ie 
series of measurements for me, which prove Michaux’s specime 
to be the same species as Hampe's ZL. minus. 2 
Michaux in his Flora Bor. Am. ii p. 297 (1803) Nee 
“ Dicranum glaucum: pumilum. YD. caulibus ramosis, oT 
foliatione crassis, foliis glaucis, convexo-canaliculatis . Bape 
subinclinato, oblongo-ovato; operculo gracilter subulato, su 
flexo. Obs. Mea varietas humillima, foliis acuminatis. Hab. :

minus, both in America and in Europe, would it not be wel ; 
adopt Michaux’s prior name for the plant of the — 
United States, and call it L. pumilum (Michx.), 1803, (4
