2Q4 SANTALACE^. Comandra. 



tbo smnmits of tlio stems : flowers U to 2 lines long, on slender pedicels, the white 

 oblong erect or slightly spreading lobes about eipiidling the green tube, which is 

 continued conspicuously above the ovary : stylo slender : I'ruit dry, glubidar, 2 or 3 

 lines in diameter; fruiting pedicels 2 to 3 lines long. 



In tlie footliills of the Siena Nevada from Mariposa County northward to Washington Terri- 

 tory and thence across tlie continent to the Saskatchewan anil the northern Atlantic SUites. 



2. C. pallida, A. DC. Diii'ering from the last in its narrower more glaucous 

 and acuter leaves, which are linear to narrowly lanceolate (or those upon the main 

 stem oblong), all acute or somewhat cuspidate ; fruit larger, ovoid, 3 to 4 lines long, 

 sessile or on short stout pedicels. — Prodr. xiv. G3G ; Watson, Bot. King Exp. 319. 



From Oregon to Colorado and New ^lexico, frequent in the mountains of Nevada ( Watson) and 

 collected by Newbcrnj in Northwestern Arizona ; probably to be found in California eastward of 

 the Sierra Nevada. 



Order C. LORANTHACE^. (By Dr. Ceorge Engelmann.) 



Evergreens, parasitic on shrubs or trees, dull yellowish-green or brownish, with 

 dichotomous branches and swollen joints, the opposite thick and coriaceous exstip- 

 ulate and entire leaves foliaceous or reduced to mostly connate scales : flowers 

 dioecious (in our genera), of 2 to 5 sepals coherent at base and valvate in aestiva- 

 tion ; anthers as many as the sepals and inserted upon them, 1 - 2-celled aiid sessile 

 (in our species) ; ovary inferior, 1 -celled, with a solitary erect orthotropous ovule, 

 the style short or none ; fruit a berry with glutinous endocarp ; seed with copious 

 fleshy albumen, enclosing a straight axile embryo with superior radicle. — Flowers 

 in our species small and inconspicuous, greenish. 



A considerable order, of about 15 genera and 300 species, distributed mostly through the trop- 

 ical regions both of the Old and New World, with a few species in the temperate zones of both 

 liemispheres. Only two genera are represented in tlie Ihiited States. The fruit contains a pecu- 

 liar viscid and tenacious clastic substance known as IJird-linic. 

 1. Phoradendron. Flowers globose, mostly 3-lobed. Anthers 2-celled, opening by 2 pores or 



slits: pollen-grains smooth. Berry globose, pulpy and scmitransi.arent. Cotyledons 



foliaceous. Leaves foliaceous or scale-like. 

 2 Arceuthobium. Flowers mostly compressed ; the staminate usually 3-parted, the pistillate 



2-toothed. Anthers a single orbicular cell, opening by a cucular slit ; pollen spinulose. 



Berry compressed, fleshy. Cotyledons very short. Leaves scale-hke, connate. 



1. PHORADENDRON, Nutt. Mistiktoe. 



Flowers globose, immersed in the rhachis of jointed spikes. Calyx 3- (rarely 2- 

 or 4-) lobed. Anthers sessile on the base of the lobes, 2-celled, the cells opening by 

 a pore or slit : pollen-grains smooth. Stigma sessile, obtuse, entire or more or less 

 2-lobed. Berry globose, pulpy, semitransparent, crowned with the persistent sepals. 

 Embryo with foliaceous cotyledons. — Parasitic on the branches of various kinds of 

 trees : spikes single or in i»airs in the axils of opposite leaves, or rarely terminal, the 

 lowest joint sterile, the others (1 to many) bearing solitary or sevenil flowcMs on each 

 side; the stannnato spikes usually with more numerous and more Horiferous joints 

 than the pistillate. Flowering in February or ^larch and maturing its fruit the 

 next winter. — Nutt. PI. Gambel, 185. 



An American genus, of about 80 species, ranging from the southern Atlantic States and Oregon 

 to Brazil and Peru, mostly tropical. Only the following si^cies are found within the limits ol the 

 United States.
