suborbicular, 0.8 X 0.45 mm. (some 0.35 X 0.3 mm.), a little narrowed below 
the orifice when dry. Operculum conic-rostrate, brownish, oblique or 
curved, sometimes as long as the capsule, 0.3-0.35 mm. Calyptra long 
pointed, split on one side to the middle. Teeth long and slender (0.135- 
0.215 mm.), very papillose, yellowish, with darker or brownish yellow base, 
divided about four-fifths their length, the parts near the middle spirally 
banded and more or less thickened. Spores pale yellow, globular, 9-18 jj, in

Fissidens synoicus was published in 1856 jin a separate, entitled: 
“ The Musci and Hepaticae of the United States east of the Mississippi 
River, contributed to the Second Edition ’of Gray’s Manual of Botany by 
Williams. Sullivant.”* It includes “Additions and corrections ” that were 
to be made to the Manual, whose pagination for the part containing the 
Musci and Hepaticae ends with page 702. On page 103 of the separate, 
which would be page 703 of the Manual, was the following description, to be 
added to those on page 24 (page 624 of the Manual), following No. 3 of the 
genus Fissidens or F. exiguus Sulliv. : 
“3 b. Fissidens synoicus (n. sp.) — Hermaphrodite; stems simple, 
inclined, 3"-6" long; leaves 12-14 (pairs ?), oblong-lanceolate, oblique, shortly 
acuminate, bordered except at the denticulate apex, the blade shorter than 
the duplicature, the dorsal wing vanishing above the base: costa continuous; 
capsule terminal, oval-oblong, erect: operculum rather long-rostrate. San 
Marcos, Texas. Wright. — A small species, distinct by its whitish green 
leaves with a close areolation, regular erect capsule, and hermaphrodite 
inflorescence.” 
Prof. W. G. Farlow writes me that the bnly writing on the specimen in 
Herb. Sulliv. is that given above where the specimen is cited. As seen by 
the direction given in the separate it was to be placed between F. exiguus 
and F. ?ninutulus, which in the Manual are immediately followed by F. 
bryoides, thus indicating its relative position. I append a fuller description, 
based on the collection from Lockport, which I identify with those from San 
Marcos, and on those in the Herb. Sulliv. It is illustrated by Plate IX. Figs. 
1-7 and Fig. ii. These are made from the Lockport moss. 
Fissidens synoicus Sulliv. Cespitose, stems mostly simple, erect or 
inclined at base, 6-12 mm. high. Leaves pale green, 8-20 pairs (mostly 
10-15 pairs), oblong-lanceolate to linear-lanceolate, short acuminate or acute 
and apiculate, 11-1.8 X 0.3-0.45 mm., the lower shorter: erose denticulate 
near the point, somewhat wavy-sinuolate below; costa subpercurrent, occa- 
sionally forming the point. Border 1-3 cells wide, or on vaginant lamina four 
cells, frequently indistinct or absent, especially on one side, usually ceas- 
*New York, George P Putnam & Co. Whether the additions and corrections were 
inserted in subsequent editions of Gray’s Manual is doubtful. My copy with the imprint 
of Ivison and Phinney. 1858, with the copyright of George P. Putman & Co., 1857, does not 
contain them. The citation is always from the separate, a very rare book.
