Nota 4. Die wenigen ausgebildeten Pollenkörner haben gewöhnlich schlaffe Wan- 
dungen und enthalten meist weniger kórnigen Inhalt als diejenigen der Stammarten. 
Nota 2, Nach dem Vorkommen der Pflanze erscheint es am wahrscheinlichsten, 
dass sie aus Eichen von J. glaucus, befruchtet durch Pollen von J, effusus entstanden ist. 
Aber auch die andere Combination mag vorkommen. — Bastarde von J. Leersii und 
J. glaucus sah ich noch nicht, obwohl Lasca (Linnaea 4834, VI, p. 490) das Vorkommen 
derselben behauptet. 
Species dubia.

and rare indigenous Phaenogamie plants, being a further Contribution to- 
wards making known the Botany of New-Zealand, in: Transact. and Pro- 
ceedings of the New Zealand Institute, 1887, XIX, p. 269. 
Plant perennial; stout, tall, dark-green, forming thick bushy tufts and patches, that 
are sub-erect, drooping, and prostrate; rhizome creeping, with many small scale-like 
bracts, and sending up numerous new shoots every vear; roots fibrous. Culms terete, 
leafless, 6—81!/5 feet long, 2 lines diameter below, smooth, minutely striate, upper 
portions soft and tender; tips very acuminate and sharp; the bases brown, glossy, 
with 3—4 adpressed sheathing bracts, the longest about twelve inches long; tips of 
bracts thin, very obtuse, sometimes acute; pith soft, woolly, and not continuous, yet not 
regularly broken or jointed. Panicle lateral, 8—12 inches from tips, large, effuse, pale- 
green, fascicled, sub 20 branchlets mostly compound; 4—3 being very large, stout, 
compressed, 2—3 inches long, each bearing at tip sub 40 compound branchlets; involu- 
cral bracts 41/; lines long, ovate-acuminate, very acute, membranous, white with a 
brown central nerve, Flowers !/9 inch long, bibracteolate at base; bracteoles ovate, 
acute, membranous, white, pedicelled, pedicels long slender; perianth segments 
lanceolate-acuminate, very acute, rather longer than capsule, their centres bright green 
with broad, white membranous margins. Stamens 3; anthers small, yellow, oblong, 
with a minute connective; filaments short, rather broad. Stigmas 3, long and spreading, 
rumpled, plumose, dark-red. Capsule sub-prismalic, turgid, obtuse, very light brown, 
or dirty-white, shining, less than 4 line long. Seeds small, numerous, bright yellowish- 
brown, convex, oblong, subclavate; testa not produced. 
Hab. In wet swampy hollows between hills, in a dense forest south 
of Norsewood, County of Waipawa; 1885—86, W. C. 
Obs. This remarkably fine rush is found growing in middlesized tufts, and also in 
very large and dense patches, with the ground thickly strewed with them in a prostrate 
state, forming several layers, all living and dark-green. It is rather difficult to force 
one's way through a large suberect patch, owing to theirheight, their very close growth, 
and their being so greatly entangled. Its extreme softness and tenderness (for a rush), 
its great length, and its prostrate habit, led me to suspect its being a species nova, when 
| first saw it; but at that time (winter) I could not procure any good specimens, Through 
ils being so soft and tender it is much browsed on and trampled by cattle, so that it is 
rather difficult to obtain whole and perfect specimens. Hitherto I have only noticed it 
growing in that one undisturbed forest swamp, where,however, it is plentiful.
