but are never axillary to the leaves, peduncles and pedicels rigid, stout. 
Flowers, including stamens, 1 inch long. Calyx pyriform widening at the 
mouth and produced beyond the ovary, lobes triangular, petals large, 
bright-crimson, oblong acute, lacerate on the margins, stamens and style 
stout. Ovary adherent only at base to the calyx-tube. Capsule 3-valved, 
upper part free. 
This plant differs from M. hypericifolia (to which it is allied) in its larger 
size, upright habit of branching, smooth bark, and position of capsule in 
the calyx. From M. colensoi (to which it is also allied) it differs in the cymes 
never being axillary to the leaves, and in the free position of the capsule in 
the calyx-tube. 
Named in honour of Mr. Sydney Parkinson, botanical draughtsman on 
Captain Cook’s first voyage to New Zealand. Collected in the Collingwood 
district, Nelson, by Mr. H. H. Travers, December, 1882.

Calochilus paludosus, R. Br. 
The present plant adds yet another genus of Orchidee to the flora of 
New Zealand. 
It was collected by Mr. H. H. Travers in the Collingwood District, 
South Island, in December last. Baron F. von Miieller, to whom speci- 
mens were sent, says: “ I took immediate notice that this Calochilus might 
be identical with C. paludosus, as you suggest, but the inner segments of the 
calyx are shorter, and the anther is less blunt; still, that may be ascribed 
to variation, and I must confess I am not clear about positive distinction 
between C. campestris, C. robertsoni, and C. paludosus, perhaps because only 
one form seems to have come under my notice in Victoria in the fresh state, 
and the others I know only from dried and not very instructive New South 
Wales specimens. It would be well if a little more material of the New 
Zealand congeners could be procured, and best of all if several flowers 
were put fresh into alcohol.”

Plate XXIX. 
For many years past I have been interested in and have devoted some 
attention to diatomaceous deposits from various parts of New Zealand, and 
propose in the present paper to give an account of some of them, with, it 
may be, a somewhat incomplete list of the species which have been found 
therein.
