91. OLEACEAE Lindl. OLIVE FAMILY 



Trees or shrubs with opposite or rarely alternate simple or pinnate exstipu- 

 late leaves and regular 2-4-parted flowers in panicles, cymes, or fascicles. 

 Calyx inferior, usually small, sometimes none. Stamens 2-4; filaments sep- 

 arate; anthers ovate, oblong or linear, 2-celled, the sacs longitudinally de- 

 hiscent. Ovary superior, 2-celled; ovules few in each cavity; style usually 

 short or none. Fruit a capsule, samara, berry, or drupe. 



Leaves pinnate; fruit a samara 1. Fraxinus. 



Leaves simple; fruit a drupe ......... 2. Forestiera. 



1. FRAXINUS L. ASH 



Trees, with rather light tough wood, petioled odd-pinnate leaves of 3-15- 

 toothed or entire leaflets, and small flowers in crowded panicles, which in 

 ours are from the axils of last year's leaves. The oblong seed fills the cell of 

 the samara or key-fruit. Ours are apetalous and dioecious, with a minute 

 calyx or none, and the fruit winged only from the summit or .upper part of the 

 terete body, which tapers gradually from summit to base and is more or less 

 margined upward by the decurrent wing. 



Leaves lanceolate 1. F. lanceolata. 



Leaves broadly ovate or cordate . . . . . . . . 2. F. anomala. 



1. Fraxinus lanceolata Borck. Handb. Forst. Bot. 1: 826. 1800. A tree 

 sometimes 20 m. tall, with glabrous foliage: leaves 1-3 dm. long; leaflets firm, 

 5-7, the blades of the lateral ones lanceolate or elliptic-lanceolate and some- 

 times elliptic, 5-20 cm. long, pale or light green, usually acuminate at both 

 ends, entire or serrate, especially near the apex: samaras 3.5-6 cm. long, each 

 with a slender linear body and a linear or linear-oblong wing which is much 

 longer than the body or rarely about equal in length and decurrent to the 

 middle or near it. F. viridis. GREEN ASH. Wyoming (on the Platte) to 

 N. W. Territory and to Vermont. 



2. Fraxinus anomala Torr. ex. Wats. King's Rep. 283. 1871. A small tree 

 3-6 dm. high; branchlets and petioles pubescent: leaves simple, broadly cor- 

 date or ovate, abruptly acute or emarginate, 3-4 cm. in diameter, longer than 

 the petiole, entire, more or less pubescent beneath: fruit wing-margined the 

 entire length, 1"2-20 mm. long, oblong, cuneate at base and acutish or emar- 

 ginate above: calyx 1-2 mm. long, persistent at the base of the fruit: seeds 

 1 or 2, 6-8 mm. long. Southern Colorado through Utah to Nevada. 



2. FORESTIERA Poir. 



Shrubs, with inconspicuous flowers, in early spring, from imbricated-scaly 

 .ixillary buds, and small dark-colored drupes. Fascicles or panicles very short, 

 few-flowered ; the staminate sessile and in a sessile, globular, scaly glomerule. 

 I'.ninclirs minutely warty.
