138 PHILADELPHUS 



P. LEWISII, Pursh. 



A shrub up to 12 ft. high, of graceful, pendulous habit ; year-old branches 

 with greyish brown, non-peeling bark. Leaves broadly ovate to ovate- 

 lanceolate ; I?? to 4 ins. long, I to 2-g- ins. wide ; coarsely and distinctly 

 toothed or, especially on the flowering twigs, entire ; with scattered hairs 

 beneath, still fewer above. Flowers five to nine, in racemes, scentless, white, 

 i^ in. across ; petals oval ; calyx smooth outside like the flower-stalk, downy 

 at the margins, and near the apex of the lobes inside ; styles divided half- 

 way down. 



Native of Western N. America, from British Columbia to California ; 

 introduced about 1823. It is one of the most elegant and floriferous of all 

 the taller species. P. GORDONIANUS, Lindley^ figured in the Botanical 

 Register in 1839 (vol. 25, t. 32), appears to be scarcely distinguishable from 

 this species, but has larger flowers, \\ to if ins. across. 



P. MAGDALENE, Koehne. 



A shrub of bushy habit, up to 6 ft. high ; young shoots downy ; year-old 

 bark peeling, smooth. Leaves ovate-lanceolate or narrowly oval, tapered at 

 both ends, finely toothed except towards the base ; I to 2^ ins. long, ^ to ^ in. 

 wide; furnished both above and below with pale, bristle-like, minute, appressed 

 hairs, but especially dense and grey with them beneath. Flowers white, 

 | to I in. diameter, borne during early June in racemes of three to nine, 

 sometimes more, blossoms ; flower- stalk and calyx hairy, purplish ; style 

 downy towards the base, shorter than the stamens ; stigmas separate ; fruit 

 top-shaped. 



Native of Szechuen, China; introduced to France by Mr .Maurice de 

 Vilmorin in 1895, and sent by him to Kew in 1897. It belongs to the same 

 Asiatic group as Satsumi, sericanthus, and incanus. Neither of the two former 

 has the close leaf-covering of bristle-like down of Magdalenae ; in addition, 

 sericanthus differs in its smooth style, as does incanus also. 



P. MEXICAN US, Schlechtendahl. 

 (Bot. Mag., t. 7600.) 



A shrub up to 6 ft. high, with hairy young shoots ; axillary buds not hidden 

 by base of leaf-stalk. Leaves ovate-lanceolate, rounded at the base, slenderly 

 pointed, sparsely toothed, three-nerved ; i to i\ ins. long, J to i in. wide, 

 with appressed pale hairs on both surfaces, but more abundant beneath. 

 Flowers cupped, solitary (rarely in threes) at the end of short, leafy shoots ; 

 \\ to 2 ins. across, strongly fragrant, yellowish white ; petals roundish, over- 

 lapping ; calyx hairy, the lobes sometimes toothed ; flower-stalk very short 

 hairy ; style about as long as the stamens ; stigmas separate. 



. Native of Mexico; and not hardy except against a warm wall. It is a 

 handsome and distinct species, most nearly allied to P. hirsutus, and, like it, 

 distinguished by the buds being exposed at the base of the leaf-stalk. 

 P. hirsutus, however, has smaller white flowers and the stigmas are united. 

 (See also ealifomicus, with exposed buds.) 



Var. COULTERI, " Rose Syringa." Petals with a blotch of rich purple at 

 the base. Neither species nor variety are very free-flowering in cultivation. 



P. MICROPHYLLUS, A. Gray. 



A deciduous shrub of densely bushy, rounded habit, ultimately about 4 ft. 

 high ; branchlets slender but rigid, downy ; bark shining brown the first year,
