Tgt2] NELSON—IDAHO PLANTS 225 
MacpribE having collected a fine series of specimens of this well known 
species, it became necessary, before labeling for distribution, to look into its 
present nomenclatural standing. In doing so the writer became convinced that 
RypBERG is right in separating the eastern and the western forms. Not only 
is the western one not stoloniferous, but the leaf distinction is even stronger 
than as stated by RypBERG. In the eastern plant the veins are large and cord- 
like, and appear singularly superficial, a character that does not appear at 
all in any one of the numerous western specimens examined. 
Sambucus ferax, n. sp.—S. glauca Nutt. in part. So much has 
been written on S. glauca, and the descriptions by Sarcent (Man. 
trees N. Am. p. 807. 1905) and by Britton (N. Am. trees, p. 852. 
1908) are so full that the plant here proposed as a segregate may 
best be discriminated by contrast: 
It is always a shrub (never treelike) 1-2 dm. high, rarely more: 
it blossoms and fruits on the season’s shoots which have sprung up 
from the ground as well as on the shoots from the shrubby stems 
(S. glauca is a tree with definite trunk and rounded top): 
twigs are glabrous from the first, not pubescent; the pith is slightly 
brownish, not white: the leaves are smooth from the first and green, 
not yellowish green: the lanceolate-acuminate leaflets are 7-11, 
not 5~9, and the teeth are not callous-tipped; they also average 
much longer, being frequently 15 cm. or more long: the inflores- 
cence is mostly very large, often 3 dm. broad instead of half that 
size; instead of a single terminal 5-rayed peduncle there are usually 
or often three 5-rayed peduncles: the flowers are distinctly larger, 
often 6-7 mm. instead of 3 mm. broad: the fruit is borne in the 
greatest abundance and seems to observe no regular season, flowers 
being still seen in great profusion when the first fruits are wholly 
mature. 
The above differences seem sufficient to warrant separating one of the 
interior shrubby forms from the tree form of the Pacific states. -That all the 
shrubs of the interior should be so separated, I am not prepared to say, but it 
will not be surprising if careful field study shows that the shrub so common in 
the interior mountain states is also distinct as well as the one here considered.’ 
The type is Macsrine’s no. 631 from Trinity, on moist slopes, August 
23, 1910, when flowers and fruit were both abundant. The large handsome 
glaucous berries are excellent for pies or jelly. 
*Since writing these notes, I have received a copy of M. E. Jones’ paper in 
which the shrub here referred to is published as S. decipiens Jones, Bull. Univ. 
Montana, Biol. Series 15: 46. 1910
