PIPER: NOTEWORTHY NORTHWESTERN PLANTS 225 
An interesting new species of the § Podo-sclerocarpus, nearest 
related to A. speirocarpus Gray and A. Gibbsii Kell. It is a pleas- 
ure to name it after its enthusiastic discoverer. 
ASTRAGALUs CyRTOIDEs Gray, Proc. Am. Acad. 6: 201 
A careful examination of the type of this plant, collected on 
the Clearwater River, Idaho, by Spalding, shows it to be without 
question A. colfinus Dougl. and not A. Gibdsii Kellogg. The 
specimens are in young flower. | 
The fruiting specimens from Carson City, Nevada, Anderson, 
which Dr. Gray referred in Proc. Am. Acad. 6: 525 to his A. 
cyrtoides, are true A. Gibbsii Kell. 
v Philadelphus confusus sp. nov. 
P. Gordonianus Bot. Calif. Not Lindley. 
Shrub, 2-4 m. high, much branched above; bark pale, flaky : 
leaves ovate, acute or acuminate, rather thin, dentate or rarely en- 
lire, sparsely pubescent, 2-5 cm. long; petioles short: panicles 
4—10-flowered, the lower one or two pairs of flowers in the axils 
of ordinary leaves : flowers odorous : calyx-lobes triangular-ovate, 
acute or acuminate, not twice as long as the tube, pubescent on 
the tips and margins within: petals pure white, oblong, 1.5—2 cm. 
long: styles united for two-thirds their length: stigmas rather 
broadly dilated : pods rather more than half inferior. 
The common Philadelphus occurring from northern California 
to British Columbia west of the Cascade Mts. We have seen 
only two specimens from east of the Cascade Mts. that we would 
tefer to P. confusus, namely: Sandberg, Heller & MacDougal, 253, 
Hatwai Creek, Idaho; H. E Brown, July 16, 1896, Cafion City, 
Oregon, ; 
As the-type of P. confusus we would designate Ad/en, 221, 
aaa on Tum Tum Mountain, Wash., Aug. 13, and Sept. 17, 
1596. 
: The species differs from P. Lewisii Pursh essentially in its rel- 
atively shorter calyx-lobes, and the styles being united for two- 
thirds their length, whereas in P. Lezwisié they are united only half 
their length, 
) P. Gordonianus Lindley is ‘a synonym of P. Lewisi as indi- 
sa Sted not only by Lindley’s figure and description but by authentic
