Oregon to central California; originally collected near San Francisco 

 by Adalbert von Chamisso. 



Rubus ursinus. Cham. & Schlecht. Liunaca 2:11. 1827; Rj-dberg N. Am. Fl. 

 22:459. 1913; Bailey Ge/zf. Herb. 1:154- 1923- 



Canes tomentose, terete, with numerous, slender, straight prickles. Leaves 3-foliolate, 

 grayish tomentose beneath with adpressed hairs above, leaflets broadly ovate, roundish, 

 doubly irregularly toothed; petioles tomentose and prickly, also the petiolules and the 

 midveins. Flowering branches angular, tomentose, and with patent slender prickles; 

 stipules lanceolate, hirsute; leaves 3-foliolate, lateral leaflets obliquely ovate, obtuse, almost 

 sessile, the tenninal ones subcordate, roundish ovate, bluntly pointed; the uppermost 

 leaves simple, cordate-ovate or somewhat 3-lobed. Flowers cor>'mbose, 3-5, on long 

 pedicels; pedicels grayish tomentose like the cah-s and with spreading, slender prickles, 

 usually without glands; calyx-lobes ovate-lanceolate with a long often crenate tip, grayish, 

 inside whitish tomentose. Petals of the staminate flowers large, oblong, white. 



California; first collected by Adalbert von Chamisso. This is the 

 very large and partially erect form so common about most thickets at the 

 lower levels. According to Bailey, Aughinbaugh, once much cultivated, 

 belongs either to this species or to R. vitifolius. 



Rubus loganobaccus. Bailey ffe»^. Wer6. 1:155. 1923- 



Canes stout, terete, tomentose at length glabrescent, densely beset with straight patent 

 prickles. Leaves 3- to 5-foliolate, petioles and petiolules densely pubescent, prickly, like 

 most of the veins beneath; stipules subulate, hirsute; lower leaflets sessile, obliquely ovate, 

 obtuse, terminal one roundish cordate or subtrilobate, obtuse or bluntly pointed, irregularly 

 or doubly toothed, rather thick, dark green above with a few scattered hairs, densely gray- 

 ish tomentose beneath. Flowering branches copiously prickly; leaves 3-foliolate, similar 

 to those of the turions, only smaller; the uppermost simple, cordate. Flowers corymbose, 

 large, bisexual, pedicels long, stout, tomentose and with patent prickles; calyx and the 

 ovate-lanceolate, long-pointed calyx-lobes pubescent and prickly; petals large, white. 

 Fruit elongate, red, acidulous; drupelets tomentose. 



Garden origin; only known as a cultivated plant; said to have origi- 

 nated in the garden of Judge J. H. Logan, Santa Cruz, California. The 

 loganberry was at first said to be a hybrid between the " common Calif omian 

 dewberry " and a raspberry. There is, however, no trace of a raspberry in 

 the character of this plant. Most likely it is a mutant offspring of R. ursinus, 

 from which it differs only in slight details and chiefly by its bisexual flowers, 

 but such can occasionally also be observed on R. ursinus. A cross was 

 raised at Geneva between the red raspberry Herbert and the loganberry. 



Rubus titanus. Bailey MSS. 



Canes extremely robust, many yards long, terete, pubescent, glabrous later on. beset 

 with numerous, stout, straight or hooked prickles from a broad base, with smaller ones
