KEY TO THE SPECIES OF JASMINUM 273 



the first, above, with thicker leaves and more erect and bushy growth 

 which seemingly does not produce good seeds and is propagated only by 

 grafting on the same, H. Carolina. [Fresh seeds (except Meehan's).] 



Symplocos, Sweet-leaf. These constitute a large group, 150 species, 

 of mainly tropic trees with alternate simple thick usually evergreen 

 leaves ; generally white, 5-lobed flowers in clusters and berry-like black, 

 red, or blue fruit. Only one species (possibly two) is either shrubby, 

 hardy, or beautiful enough to need description here. 



Himalayan Sweet-leaf — Symplocos crataegoides, — 3 to 40 feet, has 

 obovate leaves 1 to 2| inches long, closely notched towards the tip and 

 compound clusters, panicles (2-5 inches long), of small white fragrant 

 flowers, May, June. The dry drupes ripen in September and last through 

 the fall and winter, are bright blue in color and constitute the most beau- 

 tiful feature of the plants. 



An American species, Sweet-leaf, Horse Sugar (408) — Symplocos 

 tinctoria — to 18 feet, is almost evergreen with orange-brown fruit ; the 

 leaves are nearly entire, 4 to 6 inches long ; the flowers yellow, small, 

 fragrant in dense clusters, April ; the fruit ripe in September.

Jasminum. The true Jasmines are popular shrubs and vines of easy 

 culture, with white or yellow sweet-scented flowers. The corolla has a 

 long tube and a spreading 4- to 9-lobed border. The leaves are either 

 opposite or alternate and generally compound (odd-pinnate) of 3 to 9 

 blades (some of the climbing species have but 1 blade, and thus apparently 

 have simple leaves) . Most of the species need support even if not specially 

 climbing in habit. Only the diffuse-growing and thus bushy jasmines 

 are here given. Hardy only South, though two species, J. officinale 

 and J. nudiflbrum, can be grown successfully north to Washington and, 

 with protection, to Philadelphia and New York. The fruit is 2-celled, 

 2-seeded, 2-lobed, a twin berry. [Twig cuttings ; layers.]
