This very se little plant is quite different from the other species of 
the genus. It is (when fresh) of a glaucous green, with almost filiform 
stems and Sieg the latter very markedly whorled below the floral 
organs; the lea are minute, ovate-acuminate, with excurrent nerve, 
and highly papilloe at back and margin. The inflorescence is dioicous, 
the male flow nspicuous and discoid ; cies fruit often profuse, the 
capsules uoaally fase for the size of the plan 
It is widely distributed, and if, as seems shai the species described 
from various regions as listed by Oh genen abi as he suspects, all forms 
of the same thing, it extends around the hole of the South ‘Temperate 
Zone, an along the higher Andes, into eediical South America.

extremely variable species in size of plant, density of foliation, size, 
position, and form of leaf. Occasionally forms occur fu 
the more slender sid of P. australis. But. the difference in leaf-form is 
then quite marked ; in P. australis they are fledaa. secund, widely lanceo- 
in 
subulate, finely tisaate with the narrower nerve runnin into a 
usually very long flexuose arista ; the cells are also ctineidenntity smaller, 
established without any doubt their identity with this variable species. 
I have little doubt, also, uct some of the described Australian species will 
have to be reduced to P. te? 
3. Philonotis australis (Mitt.) Jaeg., Adumbr., i, 551 (1873-74). 
Syn. Bartramia australis Mitt. in Hook. f., Handb. N.Z. F1., p. 448 
(1867). B. pyriformis R. Br. ter in Trans. NZ. Inst., vol. 32, 
p. 146 (1899). 
This species is, as deseribed by Mitten, closely allied to P. calearea 
Schimp.; like that, it has the leaves character eristically falcate-secund, but 
the cells are narrower, the leaves gradually narrowed from the base, soancely 
ovate, the cells narrower, and the margin plane 
have a specimen of Bartramia puriformis R. Br. ter. which is only 
ee australis.
