 mm. long. 



Stream banks, lake shores, swamps and open woods, in N. M. (Mora, San 

 Miguel, and Taos cos.); circumboreal, in N.A. from N.E. to N.M., Calif, and 

 Wash. 



Our plants have been referred to var. monica (Bebb) Jebs., a small shrub to 

 about 2 m. tall. 



26. Salix Drummondiana Barratt. 



Shrub usually 2-3 m. tall, rarely more or less; twigs dark-brown, puberulent 

 or glabrous, soon becoming very glaucous; stipules small and caducous; petioles 

 usually 4-10 mm. long; blades elliptic to lanceolate or occasionally oblanceolate, 

 with entire somewhat revolute margins, densely white-hairy beneath, short-hairy 

 but usually soon glabrate above, mostly 4-9 cm. long and 1-3 cm. wide, occa- 

 sionally somewhat larger; aments precocious to coetaneous, sessile or nearly so; 

 scales blackish or dark-brown, long-hairy; staminate aments 2-3 cm. long; stamens 

 2, the glabrous filaments often connate toward base; pistillate aments 2-6 cm. 

 long; capsules densely short-hairy, 3-6 mm. long, with pedicel to 1.5 mm. long; 

 style to 1.3 mm. long, sometimes cleft above. S. subcoerulea Piper. 



Forming thickets in bogs, along streams and in wet meadows, in N.M. (Rio 

 Arriba Co.) ; Wyo. to B.C. and Wash., s. to N.M., Nev. and Calif. 



Fam. 44. Myricaceae Bl. Wax-myrtle or Bayberry Family 



Monoecious or dioecious shrubs or small trees with both kinds of flowers in 

 short scaly erect aments and with resinous-dotted usually fragrant alternate leaves; 

 involucre and perianth none. 



A family of about 50 species in several genera of world-wide distribution. 



1. Myrica L. Wax-myrtle 



Leaves coriaceous and evergreen (in ours) or tardily deciduous, entire or 

 toothed to lobulate above the middle, without stipules; flowers typically unisexual, 

 in the axils of small scalelike bracts and with or without 2 to 4 short entire basal 

 bracteoles not overlapping the fruit; staminate aments ellipsoid or thick-cylindric, 

 these from axillary scaly buds; stamens 2 to many; filaments somewhat united 

 below; anthers 2-celled; pistillate aments ovoid or cylindric; ovary 1 -celled; ovule 

 1, basal; stigmas 2, linear-elongate; fruit globose or ovoid, warty, commonly with 

 a waxy coat or resinous dots. 



About 35 cosmopolitan species. 



1. Leaves of flowering branches typically elliptic to broadly oblanceolate, mostly 

 2 cm. wide or more, their upper surface with resinous dots remote 

 or wanting .■ 1. M. heterophylla. 



1. Leaves of flowering branches typically narrowly oblanceolate to narrowly 

 cuneate-oblanceolate, rarely to 2 cm. wide, their upper surface 

 densely covered with resinous dots 2. M. cerifera. 



1. Myrica heterophylla Raf. Fig. 389. 



Mostly small shrubs to about 3 m. tall; branches blackish or dark-grayish-black, 

 the pubescence of leafy branchlets becoming dark with age; leaves elliptic to
