448 ROSA ROSMARINUS 



very rare in cultivation. It has a recently introduced ally in R. Willmottias, 

 from W. China. 



R. WlCHURAIANA, Crepin. 

 (Bot. Mag., t. 7421 (as R. Luciae).) 



A procumbent shrub rising a few inches only above the ground, and 

 making shoots 10 or 12 ft. long in a season. Barren shoots unbranched, 

 quite smooth, but' armed at irregular intervals with solitary curved prickles 

 j- in. long. Flowering shoots branching and more slender. Leaves 2 to 

 3 ins. long, quite smooth, consisting of five, seven, or nine leaflets, the 

 common stalk of which is armed beneath with small, hooked spines. Leaflets 

 oval, broadly ovate, or almost orbicular, from j to I in. long, coarsely toothed 

 and deep polished green on both surfaces ; stipules with jagged margins. 

 Flowers nearly 2 ins. across, pure white, produced in July and August in 

 panicles of six to ten blossoms rising out of the dense carpet of foliage ; 

 petals often more than the normal five ; sepals in. long, entire, downy. 

 Fruit globose, \ in. long, not crowned by the sepals. 



Native of Japan ; introduced to Kew from N. America in 1891. A very 

 distinct and beautiful rose, marked by its prostrate habit and exceedingly 

 glossy foliage. It belongs to the same group as, and is allied to, R. multi- 

 flora and R. Lucias. Although somewhat eclipsed now by the large number 

 of exquisite hybrids raised from it, it is well worth growing for its own sake. 

 It flowers when nearly all other wild roses are past, and for making a low 

 covering for a sunny bank few plants are better suited. Among its numerous 

 progeny are Dorothy Perkins, Lady Gay, excelsa, Alberic Barbier, Elise 

 Robichon, Jersey Beauty, Pink Roamer, etc. 



Var. RUBRA is said to be a hybrid between this species and Crimson 

 Rambler. Flowers single, \\ to 2 ins. across ; petals bright red, white at the 

 base. 



R. WILLMOTTI^:, Hemsley. 



(Bot. Mag., t. 8186.) 



A densely branched shrub, 5 to 10 ft. high, stems glaucous when young ; 

 branches slender, red-brown, armed with straight prickles j to f in. long and 

 in pairs. Leaves f to 2 ins. long, smooth (except for the stipules, which are 

 fringed with glandular hairs), and composed of usually nine leaflets. Leaflets 

 oblong, obovate, or nearly round, to \ in. long, toothed except towards the 

 base. Flowers I to i^ ins. across, bright purplish rose, produced singly on 

 short lateral twigs ; stalk \ to J in. long, smooth. Sepals lanceolate, in. 

 long, entire, smooth outside, while-felted within. Fruit roundish, orange-red. 



Native of W. China, near the Thibetan frontier ; found by Wilson when 

 collecting for Messrs Veitch in the Sangpan Mountains, at 9500 to 11,000 ft. 

 elevation. It is closely allied to the Himalayan R. Webbiana, differing 

 chiefly in the absence of glands on the calyx, and is an equally charming 

 rose with the same finely bred appearance. 



ROSMARINUS OFFICINALIS, Linnaus. ROSEMARY. LABIATE. 



An evergreen shrub of dense, leafy habit, forming a bush 6 or 7 ft. 

 high and as much wide ; young stems slender, downy. Leaves opposite, 

 linear, f to 2 ins. long, T V to -J in. wide ; not stalked, blunt at the apex ; 

 margins recurved ; dark rather glossy green above, white-felted beneath, 

 aromatically fragrant when crushed. Flowers produced during May in
