linum, and collected in New Zealand by J. D. Hooker, must be 
referred to this species 
The deep-water form (no. 9) sent by Mr. Lucas differs markedly 
from the usual shrubby 3-4 pinnate form of the species. For the 
benefit of —— we append the following description :— 
Forma nata, f.nov. Fronde compressa anguste elongata 
disticha e bail pectinato-pinnata (alioqui parce ramosa ramis pecti- 
natis) ramulos copiosos patentes lineares a natos inter sese

The frond tends to be pte elongate in erry being some- 
times 26 cm. long and 1-5 cm. broad, interrupted by the protrusion 
of a very few long branches of similar habit, which make the plant 
bipinnate. The numerous flat ramuli which occur with perfect 
n 
half of them are broken off and tru aie,

S. Lucas, no. 29 ; with cystocarps and with tetraspores. Mr. Lucas 
only found it in fruit on one occasion. He has several specimens 
which rk - over their surface, Some may reach a foot in 
diameter. It is very rare in Botany Bay.

The 1 name of this plant was first published by Harvey in 
Hooker's Flora Tasmanica, ii. 1860, p. 325. He does not describe 
it, but says :—‘‘ Fragments of a Kallymenia of large size, skint ng 
K. Harveyana, are not uncommon at Georgetown, but I have as yet 
seen no ee sufficiently perfect to enable me to characterize 
the speci of my specimens is eighteen inches broad, about 
twelve acer long, broadly foliaceous, lobed and lacerate at the 
margin ; another, of somewhat smaller size, is deeply laciniate, and 
divided aes numerous row lobes and se

widening into the cuneate base of the frond. The colour is a deep 
crimson he substance is soft, and the plant adheres firmly to 
J. Agardh was the first to describe the species (Epicrisis, 1876, 
pp- 220 and 686) from a plant sent to him Je 
Syst. after receiving more material, still ‘without fruit, 
ie speaks of the general resemblance to Halymenia kallymentoides 
(p. eet abet and says he recognizes two forms, which he describes 
as fe 
(a) K. tasmanica. Thinnish and closely adherent to paper, frond 
mostly wits or ——- lobed, margins sometimes rather sparsely

(b) K. tasthinaicn var. laciniata. Thicker, when dry sometimes 
almost cartilagous, and scarcely adhering to paper, deeply laciniate

Hep sates to regard these not as two distinct species, but, until 
fertile specimens are fostheining: as forms modified by environ- 
ment. We have not seen authentic examples of these two forms ;
