The following amended diagnosis of this species is from the same author (in Grev. i., 109):—“Seta solitary; st. erect; l. more or less erecto-patent, straight, from a broad linear flat base, broadly oblong-lanceolate, gradually narrowed into a strap-shaped point, tapering into an acute apex, lightly undulate above, canaliculate; margin acutely serrate above, teeth uniform in shape and direction; nerve very narrow, vanishing below apex, smooth at back; basal cells short quadrate, brownish, above elongate hexagonal or parallelogramic, uppermost elliptic-oblong.”

361. E. minimum, Hunt. is now ascertained to be Splachnobryum Wrightii, Muell., and can hardly be considered as indigenous, “for the spores have most probably been mixed with soil attached to some exotic, and thus accidentally scattered on the wall where it was found.”—[Braithwaite.]

SPLACHNOBRYUM. C. Muell. Verhand. Zool. Bot. Ges. Wien, 1869. p. 501.

“Calyp. dimidiate, enclosing the whole theca and embracing spirally the upper part of the seta, cleft at side, smooth, fugacious. Perist. simple, arising below mouth of caps., teeth 16 very narrow, linear-lanceolate acicular, with the articulations remote. Columella immersed. Dioicous, male fl. gemmaceous, without paraphyses. Plants small slender, with distant spathulate leaves.”

S. Wrightii. Muell. l. c. (Entosthodon minimus, Hunt. l. c. Amblyphyllum Hibernicum, Lindb. MS.)

“St. ¼–⅓in. simple sub-flexuose, pale red, slightly radiculose; l. bright green distant (base narrow, slightly decurrent), patent, flattish, obovate or spathulate, rounded at apex, margin reflexed below, entire or minutely serrulate in male, crenulate above in female plant, nerve thick, prominent at back, vanishing below apex; cells large lax, pellucid, smooth, incrassate, rhombo-rectangular at base, rhomboidal above, smaller and nearly circular at margin; caps. erect, obconical at base, sub-cylindrical, wide-mouthed, pale brown; seta slender, twisted to left; lid conical acute.” [Dr. Braithwaite, l. c.]
