This, along with the preceding, has iong iaiii in our Herbarium imdescrihed, the gift of the generous
Menzies, who gathered it in California, and probably a t San Francisco. It is, -without doubt, the L. sericeus
of Eschscholtz, and probably too of Pursh; though we have no authentic specimen to confirm this opinion.
It is among the most beautiful of tho genus, small, sufEruticoso, densely leafy, often throwing out numerous
short hranlhcs, and every where, except the corolla, clothed with densely oppressed aureo-nitcnt siilty hairs.
The fiowers are described by Eschscholtz as yeUow, though in the dried state, as that author observes, they
become tinged with purple.

ADENOSTOMA. Nov. Gen.
Calyx infundibuliformis, inferus, coriaceus, 5-angulatus, 5-fidus, lobis rotundatis brevibus
mucronulato-acutis ; tubi ore glandulis quinqué transversim oblongis carnosis munito.
Pétala 5, subrotunda, vix unguiculata, patentia. Stamina 15 erecto-patentia. Antheræ
subglobosæ. Pistillum 1. Ovarium obovato-cylindraceum, tiniovulatum ? apice oblique
truncatum pubescenti. Stylus lateralis, vix calycem longior, flexuosus. Stigma obtusum,
subincrassatum.
1. A.àeTiO%tovoafasciculata. (T a b . X X X .)
Frutex rigidus glaberrimus ramosus; rami stricri subviigati. Folia fasciculata iineari-filiformia rígida
brevissime petiolata basi stipula miniitissima suffulta. Fasciculi foHorum etiam stipulatí, stipula bifida.
Flores fasciculati in spicam interruptam terminalem aphyllam congesti, parvi, albi ; bracteis plurimis parvis
subimbricatis, ovatis, acutis, rigidis, exterioribus sæpe divisis.
It is to be regretted that we do not possess perfect fi-idt of this plant, which w'e consider as unquestionably
belonging to the Natural Order Rosaceoe, and very different from any genus yet described. In habit, it
perhaps comes nearest to some species of Spircea, yet the flowers are abundantly different : the calyx^ being
furnished with five conspicuous fleshy glands or scales a t the mouth, and the germen remaikably aud obliquely
truncated at the extremity, and there and there only very pubescent. It constitutes apparently a small rigid
slirub, glabrous in every part, with upright twiggy branches clothed with greyish-browTi bark. The leaves
are small and always fasciculated, the fascicle, as well as each individual leaf, being subtended by a stipule ;
that of the latter is bifld. Flowers iu au iutei-rupted terminal leafless spike, clustered, with many small
imbricated bracteoe at their base. It gi'ows in sandy plains in the Bay of Monterrey.

I. Horkelia Californica; foliis radicalibus p innatis 5 -7-jugis, foliolis late cuneato-obovatis
profunde serratis, calycis laciniis exterioribus 3-dentatis, petalis calyce brevioribus.— Cham,

This is a very distinct species from the H. congesta of Douglas and Hook, in Bot. Mag. t. 2880, and has
beeu Avell described by Chamisso and Schlechtendal in the Linnæa.
