& DR. M. T. MASTERS ON THE 
terminal, and surrounded at the base by numerous imbricate, 
marcescent bracts. Ovule erect, surrounded by an aril which 
ultimately forms a fleshy cup in which the ripe seed is nearly 
enclosed. The two cotyledons are linear, obtuse, leafy, and are 
succeeded by smaller leaves of the same form. 
The leaves of 7. baccata have the midrib prominent on the 
upper surface and the margins are recurved. The upper epi- 
derm is smooth, the lower papular. There is no hypoderm, but 
well-marked palisade is present. The vascular bundle is single, 
elliptic in outline, the pericycle being surrounded by an ill- 
defined endoderm. There are no resin-canals. The root-fibrils 
show a loose epiderm with root-hairs, a thick cellular cortex, 
and a single cylindrical fibro-vascular bundle in which masses 
of xylem alternate with similar masses of phloem. The pericycle 
is surrounded by endoderm-cells, the angles of which are much 
thickened by callus. 
Bertrand (Ann, Sc. Nat. sér. V. xx. 1874, p. 58) points out the 
anatomical differences between the several species, especially in 
the nature of the epiderm and the disposition of the stomates. 
The species are natives of the northern hemisphere in both 
continents, while fossil remains in various countries attest the 
existence of the genus since Miocene times. 
DacryDIvuM. 
am name taken up by Lambert (1803) from Solander*. The 
species have heterotaxic and heteromorphic leaves. The flowers 
are dicecious, the males at the ends of the branches; anthers 
sessile, spirally imbricate, two-lobed, dehiscing laterally, and with 
a prolonged spur-like connective. Pollen-grains oval or oblong. 
Female flowers solitary, terminal. The uppermost bracts are 
thickened ; one of them bears an.ovule at first inverted or placed 
horizontally, but ultimately erect and surrounded at the base by 
a tubular fleshy aril. The cotyledons are two in number and 
leaty. 
The genus is well illustrated in Sir Joseph Hooker’s ‘ Flora of 
Tasmania,’ and in T. Kirk’s ‘ Forest Flora of New Zealand.’ 
Lepidothamnus of Philippi is referable to this genus. 
The species are natives of the Malay Peninsula, Borneo, New 
Zealand, Tasmania, New Caledonia, and Chile.
