THE LISTERAS OF New ENGLAND. — In a recent study of the genus 
Listera (Bull. Torr. Cl. xxvi, 157-171, pl. 356, 357), Dr. Karl M. 
Wiegand defines for New England three species, the well-known Z. 
cordata, R. Br., examined from Maine, New Hampshire, Vermont and 
Rhode Island; Z. convallarioides, Torr. from Maine, New Hamp- 
shire, and Vermont; and a novel but characteristic plant, which 
differs from Z. convallarioides in having the oblong lip not dilated 
above nor contracted below, and in bearing near the base two incurved 
auricles. This species, Z. auriculata, Wiegand, occurs in mossy woods 
or on damp wooded banks from the White Mountains through central 
and northern Maine and northward to Quebec and Lake Temiscouata. 
In Maine, where it is apparently as abundant as Z. convallarioides, it 
usually flowers in late June, about ten days earlier than that species. —

THE LOCAL FLORAS OF NEW ENGLAND.

Ir is difficult to define the precise scope of the term local flora. 
The descriptive manual passes insensibly into the annotated list, which 
in its turn merges into mere collections of observations upon selected 
species. It is impossible to say at what point such papers cease to 
merit the title of floras or even of lists; since in indexing and bibli- 
ography it is generally best to err on the side of fulness, many short 
and popular lists are here mentioned. With the exception of papers 
on the willows, no list dealing only with a group of lower order than a 
family is included. Works which cover not only New England, but 
other regions also are usually omitted. 
The most complete previously published catalogue of New England 
floras is that included in Prof. N. L. Britton's List of state and local 
floras of the United States and British America,‘ in which 106 papers 
are credited to New England — a number more than doubled in the 
present compilation, which comes down to January 1, 1899. 
Some experimentation in classifying the works here enumerated 
has led to the conclusion that nearly all of them fall readily into two 
categories, namely: 1. Those which aim at completeness in their
