in the herbariums consulted any specimens from this state. There 
are, however, the following specimens from Maine and New Hamp- 
shire which are referable to this variety. Marine: Bangor bog, 
Orono, July 20, 1892, M. L. Fernald; Somerset Co., peat bog, Flag- 
staff, Aug. 19, 1896, M. L. Fernald; Piscataquis Co., Mt. Ktaadn, July 
8, 1900, J. R. Churchill. New HaMrsurnEe: summit of Thorn Mtn., 
Jackson, Oct. 4, 1896, C. E. Faxon. Picea mariana var. brevifolia in- 
habits chiefly mountain bogs and is distributed outside of New England 
to Ontario, northern New York and Michigan. The low prostrate 
form of the exposed tops of high mountains described by Peck as P. 
brevifolia var. semiprostrata, will probably also be found in New Eng- 
land. A form similar in habit and in the size of leaves and cones 
which I found on top of Mt. Mansfield in Vermont is apparently a low 
form of the true P. mariana, as it has dark green leaves. 
Picea rubra forma virgata comb. nov.— Picea mariana '* monstrous 
form" Gard. & Forest 8:45 fig. (1895).— Picea rubens “form” 
Sargent, Sylv. N. Am. 12:33 (1898).— Picea nigra var. virgata 
Rehder; Bailey’s Cycl. Am. Hort. 3: 1334 (1901). 
Differs from the type by the long and slender branches entirely 
destitute of branchlets. 
MassaACHUSETTS: on the base of Mt. Hopkins near Williams- 
town, one plant found by Mr. George Walker and specimens with a 
photograph sent by Samuel F. Clarke in 1894 to the Arnold Arboretum. 
A very peculiar looking Spruce and interesting as a parallel form 
to P. Abies f. virgata (P. excelsa var. virgata Caspary), Schlangenfichte 
(Snake-Spruce), found in quite a number of localities in central and 
northern Europe, particularly in Norway. A comparison of the 
figure given in Garden & Forest (l. c.) of the “snake” form of P. 
rubra and of the figures of P. Abies f. virgata published by Carrière 
(Rev. Hort. 1854: 102) and by Schübeler (Viridarium Norwegicum 
1:411, fig. 69. 1886 and Gartenfl. 1: 521. 1887) show that there 
is hardly any difference in habit between these forms of the two 
species. It may be reasonably expected, that other plants of this 
form of P. rubra will be discovered in time, as the European Snake- 
Spruce also has been found many times, usually only in single 
plants which undoubtedly originated independently by mutation, 
and sometimes in colonies; in the latter case they were probably 
seedlings of a single mother tree. The offspring of the Snake-Spruce 
represents partly the true snake form and partly forms intermediate
