52939 to 52951. RrrBUS spp. Rosacese. Bramble. 



52939. RuBUs auenophorus Rolfe. 



A very distinct species witli thick, armed steins, hairy HowerinR 

 branches, and stipitate purple jrlands at unequal lenijth. Tlie hairy 

 leaves are ternated (or the upper ones rarely simph') and green on 

 both surfaces. Tlie rachis, peduncles, and sepals are hairy, glandu- 

 lar, and a beautiful purple. The sepals recall a pincushion stuck 

 full of hlack-headetl pins. This glandular development extends to 

 the stems and petioles. The rose-colored dowers with pi'tals 5 milli- 

 meters long, are in G to 10 flowered racemes 3 to 4 centimeters long. 

 The black edible fruit is 1 centimeter wide. (Adapted from Kew 

 Bulletin of Miscellaneous Jnfonuation. HI JO. p. 382.)

52940. RuBvs aixeghaniensis Porter.

 known as Ruhu.'i nif/robarcus but apparently only a more or less 

 stable form of R. alleglianiensis. 



52941. RuBus BiFLORUs quinqtjEfloeus Focke. 



A large, vigorous-growing bush with attractive, stout, " white- 

 washed " stems 12 to 15 feet in height and ornamental foliage. 

 This plant produces rich, golden yellow, raspberrylike fruits of 

 pleasant flavor which may prove of considerable value in the hands 

 of the hybridist. (Adapted from The Garden, vol 76, p. 62.'f.)

52942. RuBUS chroosepalus Focke. 



The most valuable feature of this species is the very ornamental 

 evergreen foliage, which may be compared with that of a lime 

 tree. The slender stems, furnished with a few spines, grow 6 to 

 7 feet in a season. The simple cordate leaves, 4 inches long and 

 3^ inches wide, are glabrous above and white beneath. The tlowers 

 are borne in large panicles and have no decorative value; the fruits 

 are small and blue. Native to Hupeh and Ichang at altitudes of 

 4.000 feet. The best use for the plant Is to cover a pillar, pergola, 

 or fence. (Adapted from Gardeners' Chronicle. 3d ser.. rol. 51, 

 p. 166.) 



52943. RuBus flosculosus Focke. 



A deciduous shrub up to 12 feet high, with stout erect stems 

 arching at the much-bra nchetl top. The pinnate leaves 4 to 7 inches 

 long ai-e smooth abo\-e and covered beneath with a close white felt. 

 The small pink flowers in narrow racemes 2 to 4 inches long are 

 followed by small, very dark red or black fruits which .-ire good 

 eating. Native to central and western China. (Adapted from Wil- 

 son, A Naturalist in Western China, vol. 2, p. SI.) 



For previous introduction, see S. P. I. No. 50296. 



52944. RuBUS giraldianus Focke. 



A deciduous Chinese brandde with ornamental foliage and attrac- 

 tive slender white stems. To get the best effect, at least S or 10 

 plants should be grouped together and the old growths cut out in 

 autumn to expose the full beauty of the pre\ious summer's shoots.

A climbing shrub with strong stems and ovate leaflets green on 

 each surface. The short-pediceled flowers are axillary and clustered 

 at the tips of the branches. Native to southern and central (Jhina 

 at altitudes of 2,000 meters. (Adapted from Bibliotheca Botanica
