 which are plane m the bud with slightly indupHcate margins, and united only and often

 cent, deciduous. Stamens 4, hypogynous : filaments subulate : anthers oblong, mucronu- 

 iate. Style stout : stigma thick, 2-lobed. Ovules a pair in each cell. 



5. OSMANTHUS. Calyx 4-cleft, short, persistent. Corolla short, 4-cleft: the lobes 

 broad and obtuse, imbricated in the bud. Stamens 2 (rarely 4), on the short tube of the 

 corolla, included: anthers ovate. Style short: stigma small, entire. Ovules a pair in 

 each cell. Drupe globose or ovoid, mostly 1-seeded. 



Tribe III. JASMINES. Fruit didymous or septicidally 2-partible. Seeds ascend-

 rotate to salverf orm ; Umb 6-6-parted, the lobes imbricated in the bud. Stamens 2 

 rarely 3: anthers oblong or nearly linear. Ovary emarginate : style slender: stigma 

 usually capitate or 2-lobed. Ovules 4 (or in a S. Amer. species only 2) in each cell. 

 Fruit a didymous or 2-parted at length membranaceous capsule, circumscissile at or near 

 the middle. Seeds usually a pair in each cell, large, with a thickened and spongy outer 

 coat : no albumen. Leaves often alternate ! 



1. FRAXINUS, Tourn. Ash. (Classical Latin name.) —Trees; with rather 

 light tough wood, chiefly opposite and odd-pinnate leaves, and small flowers, in 

 panicles, developed in spring. Petals when present narrow, induplicate-valvate 

 in the bud, white : anthers yellow, large in proportion. Stigma 2-lobed. Ovules 

 a pair from the summit of each cell, only one usually fertile ; the oblong seed fill- 

 ing the cell of the samara or key-fruit. Bark of shoots ash-color. Winter-buds 

 of few and usually dark-colored thickish scales. (Shape of the wing of samara 

 variable, not rarely some are 3-winged and 3-celled.) 



Oknus Americana, Pers. &c., is probably only Fraxinus Ornus, L., and wrongly thought 

 to be American. A host of nominal species of Ash which were named by Bosc, character- 

 ized mainly by the foliage, and upon which his herbarimn throws little or no hght, must 

 pass unnoticed. 



§ 1. 6rnus, Pers. Flowers 2-4-petalous, polygamous (many perfect), in 

 loose panicles, which mostly terminate leaf-bearing branches or spring from the 

 axils of new leaves. 



* Petals 2 : stj'le manifest : Califoraian. 

 F. dipetala. Hook. & Am. Small tree, glabrous : leaflets 5 to 9, oval or oblong, 

 obtuse, serrate, mostly petiolulate, an inch or two long : panicles usually clustered on short 

 lateral spurs, naked or subtended by one or two leaves : calyx truncate and somewhat 

 toothed: petals oblong-obovate, equalling the linear anthers : fruit from linear-oblong' to 

 spatulate-oblong (usually an inch long), the flat body several-nerved on each side and 

 with sharp edges.— Bot. Beech. 362, t. 87; Gray, Bot. Calif, i. 472. Omits dipetala, Nutt.
