elliptical, round, and even heart-shaped foliage, in descending ; and which, from smooth and shining, as in 
the first instance, become pubescent, downy, and more and more tomentose. Were it not for such authority, 
we might have been induced to malfe several species out of this. Some forms of var. /3. are very closely allied 
to M. diffusa, (page 63,) and ai-e chiefly distinguishable from it by the shape of the inflorescence, and the 
much larger calyx and flower. The petioles, which, in the present plant we have termed short, are not more 
than one-fom-th of the length of the leaf; this is, however, common to most of the genus, but not to the 
following species. 
2. Metrosideros macropus; foliis oppositis ovatis longe petiolatis coriaceis glabris, corymbis 
terminalibus, floribus pedicellatis, bracteis bracteolisque oblongo-lanceolatis per inflores- 
centiam subpersistentibus, calycibus pedicellisque glabris. 
Rami cortice griseo tecti. Folia opposita, ovata, vel elliptico-ovata, basi obtusa, duas vel tres uncias 
longa, sesquiunciam ad duas uncias lata, coriacea, integerrima, glabra, supra nitida, utriuque parallelim venosa, 
inter venas reticulata, margine piano ; petiolus unciam vel sesquiunciam longus, folio dimidio brevior. Corymhi 
multiflori, basi bracteis oblongo-lanceolatis semiunciam longis involucrati. Pedunculi pedicellique glabri, 
basi bracteohs inflorescentia peracta vel citius deciduis suffulti. Calyx tui'binatus, Isevis, quinquelobus, lobis 
obtusis. Petala lobis longiora. Capsula calyce persistente infi-a medium cincta, globosa, 3-valvis, loculicida. 
Semina aptera, subulata, lineam longa. 
We have been enabled to draw up this description more fuUy by means of specimens collected by Mr. 
Macrae. It must be remarked that the character in which we were once inclined to place most confidence, the 
pecuharly conspicuous bracteas during the first stage of flowering, is sometimes so considerably impaired, that 
were it not for the uniformly long petioles, double the length, in i)roportion to that of the leafj of those 
in M. polymorpha, M. diffusa, and their allies, we had almost arranged it as a variety of the former.

1. Sicyos pacliycarpus ; ramis glabris, foliis cordatis 5-7-Iobatis denticulatis supra glabris 
subtus papilloso-scabris, cirrhis glabris trifidis, floribus masculis paniculatis foemineis capi- 
tato-congestis, fructibus ovatis rostratis inermibus. 
The leaves are decidedly but not deeply five or sometimes seven-lobed ; smooth on their upper surface, 
except towards the margin, where they are fui-nished with small white tubercles, similar to those which 
cover the whole underside, and make it rough to the touch. The male flowers are in branched panicles . 
the panicle on a peduncle about two inches long, which is axillary; the perianth is five-cleft; all the 
filam ents are connected together into a tube, at the top of which are five sessile anthers, forming a little 
head. The female flowers are numerous in each capitulum : they ai-e sessile ; but the capitulum itself is on 
a peduncle, about three-foiu-ths of an inch long, that springs from the same axil with that which supports 
the males. The fruit is ovate, about a line and a half long, suddenly attenuated into a beak which is almost 
half the length of the broad portion; many fall off before maturity, leaving only four or five to each 
peduncle: there are no spines, but the siu-face appears somewhat uneven. There is one seed in each. — 
This species appears most nearly allied to S. microphyllus, H. B. K., but differs in many particulars. It was 
collected by Mr. Collie among the volcanic rocks on Diamond Hill, in Oahu.
