RYDBERG: NOTES ON ROSACEAE 79 
23. RosA BOLANDERI Greene, Leaflets 2: 261. 1912 
This species is related to the R. Covillei of Oregon, but the 
leaflets are thinner, glandular, double-toothed and decidedly 
glandular-pruinose beneath. Crepin determined the type as R. 
gymnocarpa with the remark that the sepals were persistent. Dr. 
Greene also classified it in the Gymnocarpae, but it evidently does 
not belong there. 
CALIFORNIA: Oakland, Bolander. 
24. Rosa Pringlei Rydberg, sp. nov. 
Stem dark gray, 1 m. high or more, terete, slender, sparingly 
armed with small straight infrastipular prickles, 3-5 mm. long, or 
wholly unarmed; branches 1-3 dm. long, usually unarmed; stipules 
adnate, rather narrow, 1 cm. long or less, densely and finely puber- 
ulent on the back; the free portions lanceolate, ascending, spread- 
ing, slightly glandular-ciliate; petiole and rachis densely puberu- 
lent, not at all glandular; leaflets five or seven, elliptic, 2-3 cm. long, 
acutish at both ends, rather firm, finely puberulent on both sides, 
densely so, almost velvety, and paler beneath; flowers corymbose, 
two to five together; pedicels 1-2 cm. long, glabrous; hypanthium 
ellipsoid, acute at the base, above produced into a distinct neck, 
glabrous, in fruit 9-10 mm. thick, 12-14 mm. long, dark-purple; 
sepals lanceolate, caudate-attenuate, 12-15 mm. long, finely 
puberulent, in fruit erect and persistent; achenes inserted both in 
the bottom and on the insides of the hypanthium. 
This is related to R. pisocarpa, R. ultramontana and R. Macounii. 
The leaves are dark green above, finely toothed with rather blunt 
teeth and the hypanthium is decidedly ellipsoid, with a neck. 
The plant is almost unarmed. The type in the Columbia Uni- 
versity herbarium has no prickles, but the same number in the 
United States National Herbarium has a single straight prickle 
about 5 mm. long. This was determined as R&. pisocarpa by 
Crépin. Suksdorf’s specimen is unarmed and Sheldon’s has only 
a few prickles.
