Arrou. — A few barren stems. 



The fruit of this species appears to be everywhere rare. Specimens which seem to be 

 but slight varieties in colour or density of foliage come from India, the Eastern Archipelago, 

 Pacific Islands, Australia, and even the western coasts of South America. All the species 

 referable to this group agree in having the primary stems creeping, with numerous branches 

 more or less densely inserted, forming extended patches like Macromitrium, thus differing 

 considerably from Syrrhopodon and Calymperes. The original Codonoblepharum, founded 

 on Codonoblepharum menziesii, is in fact a Zygodon with a more complete peristome, 

 without near affinity to Thyridium or Syrrhopodon. The calyptra in Thyridium con- 

 strictum {Calymperes, Sull.), found in the Sandwich Islands and also in Borneo, of 

 which fertile stems were gathered in Samoa by the Rev. T. Powell, is very long, descending 

 below the capsule, and is in the middle finely striate, but smooth above and below ; it is 

 thus similar to that of Syrrhopodon. The Syrrhopodon obtusifolius, Lindb. (Hedwigia, 

 1868, p. 21), described with obtuse leaves, may possibly be one of the states of Thyridium 

 fasciculatum, which is very variable in the outline of the leaf points. A narrower leaved 

 moss was described in Seemann's Flora Vitiensis as Thyridium luteum, and C. Mtiller has 

 described another from the same region. 



The Australian specimens were named by Hampe Codonoblepharum subfasciculatum. 



Chaetomitrium lancifolium, n. sp. 



Caulis repens, ramis brevibus patentibus pinnatis ; folia laxe compressa, patentia, 

 lanceolata, acuta, brevissime binervia, concava, infra apicem excavata. Margine superiore 

 implana apiceque flexuosa, serrulata, cellulis angustis dorso papillosa ; pericha3tialia erecta, 

 magis serrulata ; theca in pedunculo brevi aspero inclinata, cylindracea ; aperculo convexo 

 breviter rostrato.
