For the confused synonymy of this genus see the remarks upon Pherotpfoera Hookeriana. The present is a 
very scarce plant, and apparently always prostrate, forming low bushes, with depressed branches a foot or two long; 
branchhts stonier than in Pherosphrera and Diselma, tetragonous from being densely clothed with the imbricate, 
triangular, ovate, or rhomboid leaves, which have minutely ciliated margins. Male flowers in small, oblong, termi- 
nal cones, a little broader than the branchlets. Anther with an oblong, ciliate and erose, erect, obtuse connectival 
scale, and two divaricating broad cells below. Female cone rather larger and broader than the male, its scales closely 
imbricating all round, in which respect (and habit) the genus differs from Dacrydium, to which, in the structure of 
the scale and ovule, it is very nearly allied.— Gunn says that this plant bears fleshy red berries, but I suspect a mis- 
take; there are none on the specimen, though he says some are sent. (Name from ptKpos, small, and Kaxpvs, a 
cone.)— Plate C. B. Fig. 1, male branch; 2, portion of ditto; 3, front, and 4, back views of leaves; 5, male
