32. ANEUEA, Dumort. 
Frond pinnatifid or 2-pinnate, sinuate, rather thick, with a broad unde- 
fined nerve or 0. Inflorescence dioecious. Fruit from the margin of the 
frond underneath. Involucre short, cupshaped, torn. Perianth 0. Calyptra 
subcylindric, fleshy. Capsule ovoid or oblong, on a slender fruitstalk ; elaters 
attached to the tips of the valves, each with a single broad fibre. Antheridia 
immersed in marginal receptacles. 
Id the New Zealand Flora, Mr. Mitten adopted the generic name of Sarcomitrium in pre- 
ference to that of Aneura, because the fronds have a nerve or thickened axis, and indeed 
consist of little else than axis. Names are, however, as often founded on appearances as on 
facts, and if the appearance is obvious (as in this case) the name should be retained. A con- 
siderable genus, more common in the southern than in the northern hemisphere.
