FURTHER NOTES ON SEMATOPHYLLUM. 
Elizabeth G. Britton. 
In the Bryologist for January, 1903, I stated that two attempts had 
been made to see the types of Leskea recurvans and Leskea squarrosa 
Michx. but without success. They were not to be found at the Jardin des 
Plantes nor in the Herbarium of M. Drake del Castillo. Miss Vail, on her 
visit to Paris last year, obtained information that they were in the Herbar- 
ium of M. Ferdinand Camus, who very kindly offered to loan them to me, 
so that at last I have been able to compare them with North American speci- 
mens distributed in Exsiccatae and with illustrations. Both the type speci- 
mens came from Richard’s herbarium and the notes accompaying them 
are in his handwriting and are almost identical with the descriptions pub- 
lished by Michaux (Flor. bor. Am. 2:311. 312. 1803) with a few omissions and 
transposals. These descriptions have been compared with the types. 
Leskea recurvans Rich. The type specimens of “ Leskea? recurvans ” 
are labelled with a question mark as here indicated. There are three tufts 
in good condition showing an abundance of capsules both with and without 
the lids. The old capsules are contracted below the mouth when dry as in 
Plate I, Fig. 12, Bryologist, 6:1. 1903, and all are more or less curved and 
unequal. The alar cells of the leaves are more inflated than figured by 
Sullivant in the leones, Plate hi, Fig. 7, as much so as leones Supplement, 
Plate 69, Fig. 6, and this confirms Prof. D. C. Eaton’s and C. F. Austin’s 
criticisms of these plates. 
The seta varies in length from “6-8 lines,” and the capsules also differ 
considerably in size (1-2 mm.) and degree of development. The lid also 
varies in length from the rostrate-apiculate shape figured by Sullivant, 
leones Musci, t, in, Figs n-12, to even longer and more curved forms as 
in Sull. Musci Alleghaniense No. 18, and Sull. & Lesq. Musci Bor. Am. No. 
301b. (These specimens were distributed as Hypnum recurvans var. ) 
Leskea squarrosa was cited as a synonym in No. 18 Musci Alleghaniense. 
Considering that one hundred years have elapsed since the specimens were 
collected their macroscopic appearance has not greatly changed. They 
still retain their lustre and color and are undoubtedly what has been gener- 
ally known as Hypnum recurvans Schwaegr. 
Leskea squarrosa Richard. These specimens were old and in poor con- 
dition when collected. The label states that they grew “ in humosis 
humidis ” and were collected by Beaicvois. They are mixed with hepatics 
which give them a darker green color and only a few capsules are preserved; 
these are old and deoperculate. The description states that the lid was not 
seen. The pedicel is described as “ subunciales,” apparently they are all 
shorter than in the type of Leskea recurvans , only about one-half inch long. 
A portion of Hypnum recurvans , No. 301. Sull. & Lesqx. Musci Bor. Am. in 
the Columbia Herbarium collected agrees exactly with these type specimens 
of Leskea squarrosa , and indicate that the differences are due to the greater 
moisture of the locality where they grew.
