TIMMIELLA ANOMALA (Bry. Eur.) Linipr. Laubm. Deutschl. i: 590. 1888 



\'alle de ^Mexico: Tenango {Bro. Auiablc 1686). 



This species, which grows also in California, Arizona, Louisiana, 

 and Florida, has not previously been recorded from Mexico. The 

 specimens are identical with the European moss. 



T. siibaiwiiwla is very close to T. auomala, and to my mind seems 

 to be only a subspecies or a species of secondary rank. It differs 

 from T. anoviala by the position of the male flowers, the form of the 

 acumen (which is more gradually narrowed and more acute), and by 

 the much broader costa, up to two and a half times as wide. 



TRICHOSTOMOPSIS CRISPIFOLIA Card. Rev. BryoL 36: 74. 1900 



Puebla : Rancho Santa Barbara ( 4593, 4594a, 4595, 4599) ; Rancho 

 Posadas (4807). Morelia: Cerro AzaiI (4934, 4936). Valle de

TRIQUETRELLA FERRUGINEA (Schimp.) Ther., comb. nov. 



Barhula ferrugiuca Schimp. in Besch. Prodr. Bryol. Mex. 37. 1871. 



San Cristobal {F. Uli'illcr), original si)ecimen. Puebla: Boca del 

 Monte {Purpus, in hb. Cardot), {Arsenc 4726) ; Esperanza (4742). 

 Valle de Mexico: Desierto {Bro. Amable 1419). 



The leaves are triquetrous, squarrose-spreading when moist : the 

 areolation and papillae suggest the genus Lcptodontiuni. I found in 

 no. 4726 a single capsule. The fruit of this species not l)eing known, 

 I describe it : 



Folia perichaetialia erecta. vaginantia ; pedicellus llaxidus, 1 cm. 

 altus ; capsula paruni inclinatar, oblongo-cylindrica ; o])erculum o])li((ue 

 rostratum.
