Autoicous ; resembling Mollia crispa, but in larger and laxer yellowish- 

 green tufts. Stems branched, or rarely simple, \ f in. high. Leaves 

 small below, accrescent upward, lanceolate-acuminate, acute, strongly 

 crisped when dry, the margins plane or slightly incurved ; nerve strong, 

 excurrent in a minute apiculus ; cells hyaline, incrassate, minutely papil- 

 lose, elongated at base, roundish quadrate above. Perichsetial bracts 

 resembling the stem-leaves, but broader and longer. Capsule immersed, 

 on a very short seta, fuscous, nearly spherical or oval ; lid very small, 

 indistinctly defined but acutely rostrate ; spores papillose. Male inflorescence 

 gemmiform, close to the perichaetium.

Between Lewes and Chichester, Sussex; and at Reigate, Surrey (W. E. Nicholson 1900) ! ! 

 Folkestone, Kent (H. N. Dixon). 



Mr. Nicholson kindly sent me the specimen figured, and I can confirm all 

 the remarks in his paper ; the fruit, no doubt, is very infrequent, but this hardly 

 justifies the specific name. I think it will be most convenient to maintain our 

 four British and the foreign M. Levieri as distinct species, although closely allied. 



MOLLIA ( HYMENOSTOMUM) CRISPATA (Nees Horns.} 

 Autoicous ; resembling M. tortilis. Leaves longer, lineal-lanceolate, 

 curled when dry, involute at margin, nerve excurrent in a mucro. Capsule 

 ovato-oblong, often gibbous, lid with a longer beak, peristome rudimentary.

Autoicous ; very like M. tortilis, growing in dense yellowish-green 

 tufts. Leaves erecto-patent when moist, curved and hooked when dry, 

 elongated, ovato-lanceolate, suddenly ending in a short point formed by 

 the excurrent nerve, which is brown, and stouter than that of M. tortilis, 

 margins in the upper part strongly involute, and nearly meeting in the 

 middle : cells on both sides with low papillae. Seta yellow, capsule erect 

 ovate or elliptical, sometimes gibbous and cernuous, brownish ; lid with
