trees, with whorled branches, and may be recognized by the foliage, which consists of coriaceous, obovate, toothed 
phyllodia, entirely resembling leaves, but which are really formed by the growing together of many of these, as may 
be seen by examining seedling plants, where the true leaves are found to be linear. In some species the flowers 
grow from out of these phyllodia, proving that they are not simple bodies, but consist in such cases of leaves and 
stem combined. Inflorescence and flowers of the same nature as in Dacrydium, except that the flowers of this are often 
clustered together, and sunk in fleshy peduncles. (Name from puhXov, a leaf, and khados, a branch.)

A slender tree, 60 feet high, of small girth, with whorled branches. Wood pale, very close-grained, durable 
and good. Bark used for dyeing red. Phyllodia distichous, very coriaceous, 3-1 inch long, rhomboid or ovate; 
toothed or lobed; the lobes truncate. Female flowers solitary on the margins of the phyllodia. 
2. Phyllocladus alpinus, Hook. fil.; arbuscula, phyllodiis obovatis dentatis lobulatisque lobulis erosis, 
floribus feemineis in globum carnosum connatis, semine compresso. Tas. LIII.

I have very many specimens of this plant from Mr. Bidwill and Mr. Colenso, and fear it may prove only an 
alpine variety of P. trichomanoides. Mr. Bidwill, however, thinks the contrary, judging from habit and appearance, 
characters I consider of little importance in the case of alpine forms of variable plants. "The whole shrub is smaller 
and denser than the P. trichomanoides, leaves much smaller, thicker, and more obtusely lobed. Female flowers im- 
mersed in small fleshy capitula or cones at the bases of the phyllodia. —PLATE LIII. Fig. 1, male, and 2, female

Herbs growing in watery and marshy places, often near the sea, in various temperate countries. Leaves her- 
baceous, filiform or grassy; scapes bearing slender spikes or racemes of small green flowers. Perianth of six 
concave pieces, in two rows, the outer lower than the inner. Stamens three to six, with nearly sessile anthers burst- 
ing outwards. Ovaries three to six, each with one ovule and sessile plumose stigma. Capsules three to six, one- 
seeded, indehiscent. (Name from rpes, three, and yhoxis, a point; from the three points of the fruit.)
