to such species as Cladonia uncialis, Cladonia sylvatica, etc., but its 
tendency to retain or produce squamae will readily separate it from 
any of that group. It somewhat resembles Cladonia turgida in 
color and might also perhaps be referred carelessly to a form or 
phase of Cladonia furcata. Its more slender podetia and smaller 
squamules, to go no further, will separate it from the first, and its 
lighter color together with its more erect podetia and shorter, more 
truncate branches, from the last. In the event of doubt its behavior 
under the action of caustic potash is diagnostic, the chemical res- 
ponse (yellow) being immediate and pronounced. A sheet of 
representative Wareham material showing the primary thallus and 
fully developed plants in both sterile and fertile states has been de- 
posited in the Cryptogamic Herbarium, Cambridge.—C. A. ROBBINS,

In his recent revision of Kneiffia, Pennell! has replaced the familiar 
name Oenothera pumila L. by the older O. perennis L., an equation 
already made in the Index Kewensis but overlooked in the preparation 
of all recent treatments of the northeastern flora. Dr. Pennell refers 
the variety above mentioned to the synonymy of Kneiffia perennis 
(L.) Pennell, and states that “the unusual state in which the pubes- 
cence is spreading may be considered a form." On the contrary, it 
seems to me to be altogether too striking and distinct a plant to be 
passed over without recognition in nomenclature. It apparently has, 
moreover, a definite if restricted range, being known only from the 
southern shore of the Baie des Chaleurs in New Brunswick and the 
vicinity of the Niagara River in Ontario and (?) New York.—S. F.

ANOTHER ORCHID NEW TO New ENGLAND.—The publication by 
Mr. H. W. Child? of the discovery in Vermont by Cyrus Pringle 
Horsford of Listera australis indicates that there are still species of 
this much collected group to be sought in New England. It was 
therefore, particularly interesting, while recently inserting into the
