356 FLORA OF TASMANIA. [Conifer a. 
we have together come to the conclusion, that it will create the least perplexity to retain the name Microcachrys 
tetragona for the plant figured originally as Athrotaxis ? tetragona, and whose male flowers I originally described as 
Microcachrys ; its small, regularly formed cone renders the name very applicable. The name Pherosplmra we 
transfer to the plant whose female flowers I confounded with Microcachrys, and whose male flowers being collected 
into almost globose amenta, will justify the appellation ; and for the plant which Mr. Archer supposed to be my 
female Microcachrys we propose the name Diselma, in allusion to the two o villiferous scales. I have in this matter 
to express further my obligation to Mr. Archer, both for his assistance in settling the synonymy, and for some very 
valuable notes and observations upon the pollen and ovules, etc., of many of the Tasmanian Conifers, made upon 
living specimens. I may add that the Diselma and Microcachrys have quadrifarious branches, and are all but 
undistinguishable, except bj their female flowers; the branchlets of Dacrydinm FraakUnii and Pherosphara 
Hooheriana, which have leas n gularly imbricated leaves, are also almost undistinguishable when not in flower. 
I have no description of the habit, etc., of Pherosphcera, which, from being mixed with Microcachrys, is pro- 
bably a prostrate plant, The branches are slender, very much branched, and the leaves slightly compressed on 
each side of the keel. Male cone broader than the branchlet ; stamens like those of Athrotaxis. Female cones 
decurved, small, of six to eight boat-shaped, deciduous scales, each bearing a solitary ovule, with two complete 
integuments.— Plate XCIX. A, male, and B, female plants ; 1 and 2, front and back view of leaves ; 3, male

Distrib. Alps of Yictoria, Mounts Buller and Hotham, Mueller. (Cultivated in England.) 
Generally a small straggling bush, but sometimes rising to a tree 13 feet high (Archer). Branches spreading. 
Leaves inserted all round the stem, or obscurely bifarious, spreading, often somewhat recurved, linear or linear- 
oblong, obtuse, acuminate in var. /S, a~J inch long, tapering to a very short petiole, glaucous beneath, with very thick 
margins and costa. Male spike* cylindrical, wsurcely so long as the leaves, sessile, solitary or fascicled. Pollen-grams 
curved. Drupe small, two lines long, elliptical, seated on or towards the apex of one fork of a bifid, fleshy, scarlet, 
subcylindric peduncle, which is larger than the drape, and consists of several fleshy bracts adnate to the swollen 
peduncle.— This is most nearly allied to the New Zealand P. nivalis, Hook., which differs in its blunt connectivum. 
Mr. Archer agrees with me in considering that P. Laicrencii is only a variety of P. alpina, whence it becomes
