18 BOTANY OF THE VOYAGE OF THE SULPHUR. 
Fruticulus ante foliorum explicationem florens. Ramuli crassi, cortice cinereo glabro, vegetiores 2-3-pol- 
licares, plerique multo breviores. Internodia (ex cicatricibus folioram delapsorum) pauca. Ad apices ramu- 
lorum, e gemma squamis fuscis persistentibus suffulta, racemi oriuntur 6-12 lin. longi, 8-12-flori, minute 
puberuli, et hine inde folia pauca parva explicari incipiant. Pedicelli divaricati, lineam longi. Calycis tubus 
fere 2 lin. longus, cylindricus, crassiusculus, glaber ; laciniee semilineam longee. Petala ovata, calycis laciniis 
dimidio breviora, ad faucem inserta. Stamina 5, petalis equilonga. Ovarium in fundo calycis brevessimum, 
placentis 2 parietalibus, ovulis numerosis. Stylus apice brevissime bilobus, lobis intus stigmatosis, placentis 
contrariis. Fructus jam paullo grandefactus siccus videtur. 
A scrubby leafless shrub, with small but very pretty and highly fragrant 
flowers.

UMBELLIFERE. 
58. Erynerum petiolatum, Hook.—Torr. et Gr. Fl, N. Amer. 1. p. 604.—Rio Sacramento. 
CORNACER. 
59. Cornus glabrata, sp. n., ramulis erectis cymisque glabris vel vix minute puberulis, foliis 
ovatis acuminatis basi angustatis supra sparse minuteque puberulis subtus glaberrimis, cymis parvis 
depressis, drupis globosis.—San Francisco. 
Resembles the C. stricta in habit and in the form of the leaves, but has a 
somewhat glaucous foliage and inflorescence; the cymes are much more compact 
and the flowers fewer ; they appear also to be smaller, from the vestiges remain- 
ing on the specimens which are in ripe fruit. 
LORANTHACES. 
60. Viscum flavescens, Pursh.—Torr. et Gr. Fl. N. Amer. 1. p. 654.—San Francisco, on the 
oak, ash, walnut, willow, and birch, but never on the plane, although that tree be very common. 
61. ARcEUTHOBIUM orycedri, Bieb.—Torr. et Gr. Fl. N. Amer. 1. p- 654.—On pine trees in 
Upper California. . 
Besides the stations already known for this parasite on the conifere of 
N. W. America, Southern Europe, and Southern Russia, it has been found by 
Linden on pine trees on the Peak of Orizaba in Mexico; and on the closest 
examination of the dried specimen, I am unable to detect any difference 
between the European and Mexican specimens. Botanists do not, however, 
agree about the colour of the fruits. In California they were found to be 
nearly black, with a yellow top.
