unculo foliis bi’eviore, involucri foliolis foliaceis lanceolatis integerrimis umbella compacta 
simplice longioribus. 
First discovered, along with the following species, by Mr. Menzies. The general similarity of the plant 
to Arctopus capensis has suggested the specific name. There are scarcely any stems, and the umbels are 
nearly concealed among the leaves, which are almost fringed with long naiTow and much acuminated teeth, 
the larger ones of which are likewise so fimbriated. 
2. Sanicula Menziesii ; caulescens, superne subpaniculata, foliis longe petiolatis profunde 
trifidis, lobis lato-obovatis cimeatis inciso-serratis serraturis acuminatissime mucronatis, 
umbellis compositis, involucelli foliolis lanceolatis acutis umbellam sequantibus. 
Evidently allied to the S. arctopoides ; but having a stem nearly a span high, with compound umbels, 
the umbellules globose, flowers small, yellow. 
1. Eryngium Linn. 
There are no leaves, and only the extremity of a stem of a solitary specimen, so that we are unable 
satisfactorily to determine the species.

1. l^ei-SLcXeum Sphondylium? Linn. 
A wretched specimen of this obliges us to put a mark of doubt to the name. 
1. Helosciadium ? Calif ornicum ; procumbens? foliis pinnatis pinnis 8-11 ovatis acutis 
inciso-serratis inferioribus pinnatifidis vel pinnatis, pinnulis paucis, umbellis lateralibus ter- 
minalibusque, involucris involucellisque plurifoliolatis, stylis elongatis. 
This has a good deal the habit of the Helosciadium, repens of Europe, but is vastly larger, with more 
numerous and more divided pinnae. It appears likewise to depart from the generic character, in having 
several leaves to the involucre, and a long style. The fruit is essentially the same in both. 
The Herbarium contains two other Umbelliferous plants, from California, but with fruit so young, that we 
cannot refer them to any known genus. Both have their leaves many times divided into very narrow, linear, 
almost filiform segments, and the vagina of the leaf is singularly large and inflated. The one is nearly 
stemless, very pubescent, almost woolly about the umbels and involucres. The involucella are about as long 
as the umbellules, broadly lanceolate, and apparently entire : the very short stems (many arising from the 
crown of the root) bear each a peduncle about as long as the leaves. The other has a flaccid, apparently 
procumbent stem, with remote leaves, and is nearly glabrous. There are no involucres, and the involucella 
are lobed in a somewhat palmated manner, with the lobes acute, and about as long as the small compact 
umbellula.

L 'Her it.) 
This exactly agrees with our specimens of C. alba, from the United States ; and, indeed, scarcely differs 
from C. circinata of L’Heritier, with which Chamisso unites it, except in the shape of the leaves. It extends 
as far north as the Columbia on the western side of America.
