P. DELAY AYI, L. Henry. 



A shrub up to 10 ft. high ; young shoots slightly hairy. Leaves ovate, 

 rounded or heart-shaped at the base, slender-pointed, toothed, dark green and 

 hairy above, felted with whitish hairs beneath, i to 3 ins. long, \ to \\ ins. 

 wide. Flowers fragrant, pure white, I to i ins. across, produced in clusters 

 of seven to eleven. Petals ovate, with tapered ends, often lobed or undulated 

 at the margins, spotted or margined with purple at the back ; calyx smooth 

 outside, the lobes triangular-obovate, downy towards the tips inside ; style as 

 long as the stamens, smooth ; stigmas separate. Fruit \ in. long. 



Native of W. China ; discovered and introduced to Europe by the Abbe 

 Delavay in 1887. It flowered first at the Jardin des Plantes in 1890. In 

 many of its characters it resembles P. tomentosus, Wallich, but the leaves 

 are more hairy above, and strongly felted beneath, and the fruits are smaller. 

 A pretty fragrant species, producing its flowers in neat dense clusters in 

 June. 



The Philadelphus figured Bot. Mag., t. 8324, under this name is P. 

 BRACK YBOTRYS var. PURPURASCENS, Koehne. It was introduced by Wilson 

 about 1904. From P. Delavayi it differs in the much less hairy leaves, 

 narrower flowers less numerous in the clusters, and in the more rounded 

 petals. 



P. FALCONERI, Sargent. 



(Garden and Forest, 1895, fig. 68.) 



A shrub up to 10 or 12 ft. high, forming a dense mass of slender, arching 

 branches, which become a dark purplish brown the second year ; young shoots 

 quite free from down, slightly ribbed. Leaves ovate to ovate-lanceolate, 

 broadly wedge-shaped at the base, slender-pointed, distantly and minutely 

 toothed ; I J to 3^ ins. long, \ to if ins. wide ; smooth except for a few hairs 

 on the margins and ribs beneath when young. Flowers delicately scented, 

 pure white, \\ to 2 ins. across, produced at the end of twigs 2 to 4 ins. long 

 in racemes of three to seven flowers. Petals oblong-lanceolate, in. wide, 

 slender-pointed ; calyx smooth, except for minute down at the margins of the 

 lance-shaped lobes ; styles separated half-way down. 



The origin of this mock orange is not known ; it was first distinguished 

 in Parson's nursery at Flushing, Long Island, U.S.A., and is thought probably 

 to be a native of Japan. It is not one of the best of the genus, and although 

 elegant in habit, is shy-flowering, at least in this country. Its long, narrow 

 petals make it one of the best distinguished of the genus. 



P. GRANDIFLORUS, Willdenow. 



A shrub up to 15 ft. high, with the year-old bark peeling, young bark 

 smooth, becoming chestnut brown. Leaves ovate to ovate-lanceolate, rounded 

 or tapered at the base ; slender-pointed, sharply toothed, prominently 

 three- or five-nerved ; i^ to 5 ins. long, -f to 2^ ins. wide ; smooth except for 

 tufts of down in the vein-axils, and bristles along the chief veins. Flowers 

 scentless, 2 ins. wide, pure "white, produced at the end of leafy twigs, singly 

 or in threes, and sometimes (in cultivated plants) in cymes of five flowers. 

 Petals orbicular j calyx smooth outside, the lobes slenderly pointed, downy
