Our specimens of this plant are very nearly allied to, if not the same with R. maritimis. It is gathered
by Mr. Douglas, at the mouth of the Columbia, and by him and Drummond nt Hudson’s Bay; and wo have
the same from Patagonia.

Very nearly allied to P. martimum, but quite distinct.

Whale-Ship Bay. Sometimes, though rarely, the fascicles of flowers, instead of being arranged in a dense
liead, are situated singly at the extremities of short branches; this is probably what Sir James Smith means
by saying that they are proliferous, and ought perhaps to be viewed as the normal state of the plant: the
uniform abbreviations, and almost total disappearance of these little branches, causing the appearance we
have above characterised, and Avhich is the common state in the specimens before us. The specimens, however,
entirely accord with our origmal ones from Mr. Menzies.
2. Eriogonum arachnoideum ; caule suffruticoso subprolifero, foliis subradicalibus approximatis
alternis longe petiolatis ovatis m argme undulatis subtus dense tomentosis supra primum

This species, although it sometimes bears a head of flowers, never seems to present the ^■gregated
appearance of the last one, nor of the E. latifolium, Sm., from which it is truly distinct. The long petiolated
leaves are seated at the apex of a short ramification; but the greater number of them are radical.

1. T e tran th era ? Californica; foliis perennantibus oblongo-lanceolatis vix acutis penninerviis
reticulato-venosis glabris, pedunculis axillaribus simplicibus, floribus pluribus involucratis
hermaphroditis ?
Involucrum tetraphyllum, deciduum. PencniAzam hexaphyUum; foliola subrotunda concava pellucido-
punctata. Stamina 12, duplici ordine disposita; 6 exteriora, antheris introrsis; interiorum tria, foliolis
calycinis exterioribus opposita, fertilia, antheris extrorsis ; tria, laciniis interioribus opposita, subulata, absque
antheris. Glandules sex, magnæ, subrotundæ, angulatoe inter staminum interiorum exterionunque series,
bisque alternantes. Antheræ 4-loculares. Germen ovatum, in stylum brevem apice subuncinatum attenuatum:
subcapitatum.
The flowers are too little advanced to permit us to ascertain whether the pistillum becomes fertile, and
the plant consequently hermaphrodite : it however appears to us to be so. The inflorescence and involucrum
are those of a Tetranthera, while the hermaphrodite flowers, and somewhat capitate stigma allies our plant
to Ocoteu. In one specimen Ave have observed the remains of the calyx after the drupe has fallen away,
from which it appears to be cupuliform, entire, coriaceous, and persistent. Tbe peduncle is monocaiqiic, or
beais but one fruit, and is much shorter than the leaves.

The specimens differ somewhat from the Europæan ones, by the leaves being rough, although scarcely
serrated on the margin, and by having a slight mucro. The glands of the involucrum are lunate and tivo-
horned, otherwise our specimens might have been referred to E. marginata, Pb.
