CoLengo.—0On new Ferns, 429 
The following description of this plant indicates it to be closely allied 
to Pomaderris apetala, Labill., which is a native of Australia and Tasmania; 
but as it differs in its growing to a much larger size—that species being a 
mere shrub like the kumera-hau /P, elliptica) of New Zealand, whereas 
the tree now described grows to a height of 20 feet, with large stems 5 or 6 
inches in diameter—I have thought it better to distinguish it by a specific 
name, and have adopted that by which it is known to the Maoris. 
Pomaderris tainui, n.s. 
A small shrubby tree, 20 feet high, with numerous irregular branches; 
smooth brownish-grey bark; young branches and under side of leaves 
covered with white stellate tomentum ; leaves 2 to 8 inches long, elliptic- 
oblong, obtuse at both ends, irregularly crenulate, glabrous and dark 
green on the upper surface, with distant stellate bases on young leaves, 
principal veins very prominent, buff-eoloured. Flowers small in open thyr- 
soid panicles, leafy at the base, buds nearly globular; calyx about 1} lines 
long with stellate leaves, the tube being very short; petals 0; anthers tipped 
by a small gland; styles divided to the middle with club-shaped, almost 
capitate stigmas ; capsule not seen. 
Habitat: Sea Coast, south of Mokau River. In flower 5th Dec., 1878.
