39593. ROSA GIGANTEA. From E. D. Sturtevant, Hollywood,
Cal.  A rampant climber with usually unarmed flowering branches
and solitary white to lemon-yellow, single flowers, 5 to 6 inches
across.  Leaflets usually five, nearly oval, smooth, and firm.  Fortune's 
Double Yellow is said possibly to have arisen from crosses
with this rose or to be a variety of it.  Quite tender except in the
South.  Too large for greenhouses.

29729. ROSA GIGANTEA X (?)[illegible]. Belle Portuguoise rose.
Several remarkable hybrids have been made between the giant
climbing rose of Burma and other cultivated varieties.  This one is
from the Lisbon Botanic Garden, without data as to parentage.  In
California it has proven exceedingly vigorous and produces in 
profusion extremely large, creamy white, double blooms, rose tinted.
Doubtless tender.  Easily broken by winds.

40193. ROSA SERTATA. Rose.  Presented by the director,
Royal Botanic Gardens, Kew, England.  Shrub of trim habit, 5 feet
or more high, with graceful, slender branches bearing small, 
gray-green leaves composed of 7 to 11 sharply- toothed leaflets; delicate
purplish-red flowers and deep red, egg-shaped hips.  Very dainty
rose allied to E. webbiana and R. willmottiae.  Native of Central China.
Introduced at Kew by E. H. Wilson in 1907.

40699. ROSA SWEGINZOWII. Rose.  Collected by F. N.
Meyer near Sanszemiau, Kansu, China. A wild rose resembling Rosa
hugonis in habit; of very vigorous growth and possessing remarkably
broad spines, which vary much in size and number on various 
specimens.  Bush 5 to 10 or more feet high.  Flowers deep rose color.
Found on rocky mountain slopes at 5,000 to 8,000 feet altitude.
Possibly of value in hybridization experiments.

40595. RUBUS IRENAEUS. Shrubby Chinese Rubus.  Presented 
by Vicary Gibbs, Elstree, Herts, England.  One of the most
striking and remarkable of the simple-leaved forms.  The evergreen 
foliage suggests coltsfoot in size and shape, but has a curious
metallic luster on the upper surface.  Stems prostrate, covered with
dense, gray down; flowers white. Suitable as covering for semi-shaded 
slopes.  Fruit large, red.

39187. RUBUS ROSAEFOLIUS. From G. Regnard, Port Louis,
Mauritius.  Yellow-fruited variety.  This is very scarce, probably
because it is planted with or near the red form with which it becomes
cross-fertilized and the red predominates.  Should be planted in
sheltered or shady position in deep, rich soil.  Requires considerable
watering.
