Memoranda of an Excursion 
This juice is used by the natives of these parts in writing, as 
a substitute for ink; but, like most other simple vegetable 
(lyes, is very evanescent. The natives call the plant Kokihi. 
A small straggling procumbent plant, which at first sight I 
supposed to be Anchusa spathulata, Roem ., also grew here; 
but that plant is described as possessing “ foliis ovatis obtu- 
sis,” which this one has not; to that natural order, however, 
it belongs. The summons being given, to dine and march, 
I obeyed ; and, leaving the seaside, struck inland, over low 
sand-hills and through a long swamp of Phormium. About 
5 p.m. I reached the river at Turangunui, a village in the inner 
N.W. angle of Poverty Bay. Crossing the river in a canoe, 
I made the best of my way to Kaupapa, a church-mission 
station, where Archdeacon Williams resides. This place I 
reached at 7 p.m., quite tired. The very hospitable recep¬ 
tion, however, which we all received from the Archdeacon, 
went far towards causing us to forget the toils of thejourney. 
I may here remark, that the White Mangrove (Avicennia 
resinifera, Forst ., A. tomentosa? Linn.), so very common 
in salt water creeks and marshes in the northern parts of the 
island, was not seen anywhere on this line of coast. The 
natives say, that it does not grow in these parts; their name 
for this tree, is Manawa. 
At Poverty Bay I remained several days, and during my 
stay obtained specimens of several new and little known 
plants; among which I may notice—a fine spiny shrub of 
the Natural Order Rhamnacece (probably of the genus Dis- 
caria, Hook.), which grows plentifully here in the alluvial 
plains on the banks of the river. It attains the height of 
2-4 feet, and will, doubtless, make an admirable fence. The 
natives give this plant the expressive name of Tamatakuru, 
i. e. Standing-face-beater.—A very lovely and fine moss, 
with large membranaceous leaves;—a one-flowered Composi - 
taceous plant, possessing an elegant coloured and imbricated 
involuere;—and a curious minute Lenina- like floating plant, 
were among the number of my spoils. I was rather surprised
