respectively, and the northeastern limit of S. Boottii still remains 
Virginia and of C. americana, Missouri. 
Without prolonged discussion, it seems important to publish the 
following enumeration of plants, accredited to Rhode Island in the 
recently published list, which, until unquestionable specimens are 
found, cannot be accepted as occurring in the state:

Equisetum hyemale. Undoubtedly var. affine. 
Lycopodium complanatum. Undoubtedly var. flabelliforme. 
Picea canadensis. If in Rhode Island cultivated and possibly escaped. 
Abies balsamea. If in Rhode Island cultivated and possibly escaped. 
Thuja occidentalis. If in Rhode Island cultivated and possibly escaped. 
Juniperus horizontalis. Although listed by Bennett, as J. Sabina, 
var. procumbens, the species is not well vouched for from south 
of Maine and Vermont. 
Sparganium simplex. The Rhode Island records belong to S. amer- 
icanum. See RnHopona, ix. 86-89 (1907). 
Potamogeton perfoliatus. The Rhode Island plant is P. bupleuroides. 
Triglochin palustris. Listed by Bennett, but no authentic stations 
known from south of Maine. 
Sagittaria heterophylla, var. angustifolia. Based upon Bennett's S. 
variabilis, var. angustifolia, which was the slender-leaved S. lat- 
des (See J. G. Smith, N. A. Sp. Sagittaria and Lophotocarpus, 
9, 12). 
Paspalum laeve. Presumably not P. laeve. Bennett’s record may 
have been based on either P. pubescens, P. Muhlenbergii or 
P. psammophilum, all of which occur in Rhode Island, although 
not included in the new list. 
Panicum philadelphicum. Said to have been reported, as P. minus, 
by Mr. Walter Deane in Ruopora, vi. 151. This paper by Deane 
deals exclusively with Polemoniaceae and Hydrophyllaceae and no 
grass is mentioned. P. minus was recorded from Rhode Island 
by Fernald, Ruopona, viii. 220, but that plant has proved to be 
P. Tuckermani, RHODORA, xxi. 113. 
Panicum xalapense. A southern species not known in New England. 
The record was based on Bennett's P. laxiflorum, a name used 
by him to cover plants now included under P. spretum, P. Lind- 
heimeri and vars. (See RHODORA, xxiii. 226-228), P. meridionale, 
P. albemarlense, P. tsugetorum, P. columbianum, P. oricola and P. 
sphaerocarpum, all of which are known from Rhode Island and most 
of them recorded in papers cited in the bibliography, though not 
included in the new list. 
P. oligosanthes. Based on Bennett’s P. pauciflorum which was 
P. Scribnerianum, a species common in Rhode Island. 
Danthonia sericea. Based upon Bennett’s record, but there is no 
satisfactory evidence of the species in New England. D. compressa, 
which is common throughout most of Massachusetts and Con- 
necticut and is doubtless in Rhode Island, is not included in either 
list and the record of D. sericea was presumably based upon that 
species. 
Glyceria fluitans. Based upon Bennett's record and doubtless referring 
to either G. septentrionalis or G. borealis. 
Elymus canadensis. Based on Bennett’s record, which belongs to 
E. riparius Wiegand, RHODORA, xx. 84, a species properly included 
in the list. 
Cyperus flavescens. Based merely on Bennett’s record, which did 
not belong to C. flavescens (See Ruopora, x. 139).
