by the growth of the capsule it splits and becomes cucullate, 

 cartilaginous, smooth. Inflorescence: $ and £ mixed together 

 in the same inflorescence.

In an immature state the calyptra covers the entire cap- 

 sule and tightly clasps the seta, as in the genus Calymperes, 

 but on nearing maturity the growth of the fruit ruptures the 

 very cartilaginous calyptra, when it becomes truly cucullate, 

 and is pushed upward, covering only two-thirds of the capsule. 

 The plant is therefore a true Pottia. 



Orthotrichum graphiomitrium, sp. nov. Plate XXXVI. 



Autoicous. Stems subrepent or laxly pulvinate ; branches 

 erect, lin.-l-f in. long, more or less branched. Leaves laxly im- 

 bricated, patent, when dry appressed but not much altered ; 

 stem-leaves oblong-lanceolate, gradually acuminate, comal 

 leaves larger, perichaotial leaves longer and narrower than the 

 comal ones. Nerve stout, carinate, vanishing within the apex ; 

 margins quite flat. Cells at the base long, yellow, above 

 round, distinct, papillose. Capsule on a very short seta, 

 hardly visible above the leaves, ovate, smooth, striae very 

 indistinct, narrowed gradually below. Stomata on lower part 

 of capsule superficial, large. Operculum conic, rostellate, with a 

 red line round the base. Calyptra conic, golden-yellow, darker 

 at the apex and base, covered with long, jointed, pale-yel- 

 low hairs, plicate, base lobed. Peristome, outer of 8 teeth 

 bigemmate, greyish-orange, obtuse, cilia 8, nearly as long 

 as the outer teeth, broad, consisting of two rows of cells, pale- 

 grey. Male inflorescence gemmiform, axillary in the lower 

 leaves of fertile branches, bracts ovate-obtuse, nerved three- 

 quarters, cells of lower half brown, antheridia about 12, 

 paraphyses few or 0. 



Hah. On the stems and branches of small trees at high 

 elevations.

 Miiller). On " ribbonwood " trees, Benmore ; T. W. N. B. 



This very handsome and distinct moss, often of a bright- 

 golden colour, is extremely local, but very abundant in places 

 where it is found. The subrepent mode of growth is unusual 

 ill Orthotrichum. It creeps along branches with quite the 

 habit of Macromitrium, and forms patches 7in. or 8in. 

 long.
