attenuated toward the apex ; their leaves crowded, when dry not or hardly' 
at all undulate, when moist slightly turned to one side, lanceolate, on the 
average i. 40-1.45 mm. long and 0.30-0.35 mm. wide, at the broad truncate 
apex coarsely three- or four- toothed, narrowly margined by two or three rows, 
of elongated cells, involute clear to the base so as to be almost tubular, entire. 
Hyaline cells reenforced by numerous fibril-bands, on the inner surface of' 
the leaf with comparatively few generally unringed medium sized pores in* 
the cell angles, on the outer surface with hardly any spores except in the- 
lower cell angles, but occasionally weakly ringed pseudo-pores occur in short 
rows along the commissures of scattered cells. Chlorophyll cells in cross-sec- 
tion usually trapezoidal and exposed on both sides of the leaf, with the- 
longer of the parallel sides exposed on the outer surface, but triangular cells- 
occur sporadically, in which case they are enclosed on the inner surface of 
the leaf by the strongly under-arching hyaline cells. — Massachusetts, i6>

This species may be distinguished from Sph. cuspidatum by the very- 
narrowly margined branch leaves, from Sph. angustilimbatum by much 
smaller stem leaves which are not fibrillose to the base, and which have 
the margins broadened below, as well as by the mostly three-branched fasci- 
cles with equally divergent branches.

THE TYPE LOCALITY OF SPHAGNUM FAXONII. 
Harley Harris Bartlett. 
The March number of Rhodora contains a translation ffom Hedwigia of 
the original description of Sphagnum Faxonii Warnst. There only the fol- 
lowing meagre information is given as to the origin of the type specimen : 
“Massachusetts, 16 Sept., 1891, leg. Faxon.” Warnstorf has been so kind 
as to send me part of his type material in order that I might match it with 
more accurately labeled specimens in the duplicate collection of Faxon 
Sphagna at the Harvard Cryptogamic Herbarium, and thus gain accurate- 
knowledge as to the type locality. Search for plants collected on 16 Sept.,. 
1891, proved successful, — enough were found to prove beyond peradventure 
that on that date Mr. Faxon collected at Streeter Pond in Lisbon, New 
Hampshire. Furthermore, on that date he collected no peat moss more- 
closely allied to Sphagnum cuspidatum (the nearest affinity of Sphagnum 
Faxonii is with this species) than Sphagnum recurvum var. parvifolium. 
It seems necessary to conclude, therefore, that both the locality and date 
given in Warnstorf’s article are incorrect. 
An examination of all the Sphagnum cuspidatum and allied species in 
the Faxon collection showed but one number which matched the type mate- 
rial of Sphagnum Faxonii sent by Warnstorf, namely no. 1049, collected at 
Sunken Heath, Mt. Desert Island, Maine, 29 June, 1891, by Mr. Faxon, in 
company with Mr. Rand. This number agrees with the type not only in 
structural details, but also in those elusive characters of habit which so 
often give individuality to all the material of the same collection. In the
