1735 m., 22 July, 1904, C. G. Pringle, no. 8952 (lib. Gr.). The spe- 

 cies is well characterized by its long narrow leaves, white flowers with 

 narrow perianth-divisions, greenish filaments and style. It is apparently 

 most nearly related to H. adnata, Herb. 



Myrica Pringlei, n. sp. Shrub, 3 to 10 dm. high : stem and branches 

 covered with a reddish or gray bark and dotted with numerous lenticels ; 

 ultimate branchlets at first pubescent, later glabrate : leaves petiolate, 

 oblanceolate to oblong, 1.5 to 5 cm. long, 0.5 to 2 cm. broad, obtuse to 

 rounded at the apex and submucronate, sparingly dentate towards the 

 apex, entire in the lower half and abruptly to gradually narrowed into 

 the 1-4 mm. long petiole, dark green above, paler beneath, sparingly 

 pubescent and densely resinous-dotted on both surfaces in the early 

 stages, later glabrate, becoming thick and firm in texture and somewhat 

 verrucose above ; midrib and the subhorizon tally spreading lateral nerves 

 rather prominent on the under surface : pistillate catkins solitary in the 

 leaf-axils, slender, 5 to 12 mm. in length : flowers scattered, 1 in the axil 

 of each bract ; bractlets or scales at the base of the ovary 4, ciliate ; 

 ovary densely covered, except at the very top, with wax globules ; styles 

 somewhat flattened : staminate catkins solitary in the leaf-axils, 1 to 2 cm. 

 in length ; rhachis sparingly pubescent, resinous-dotted : flowers scat- 

 tered ; stamens 4 to 12 ; anthers often roseate to purplish: mature fruit 

 not seen. — Mexico. State of Puebla : pine forests about Honey 

 Station, altitude 17G5 m., 25 April, 1904, C. G. Pringle, no. 10,002 

 (hb. Gr.). 



The species here described is quite distinct from anything in the genus 

 hitherto recorded from Mexico, and of the northern representatives it 

 approaches most nearly M. carolinensis, Mill., from which, however, it 

 differs in the longer and looser-flowered staminate and pistillate catkins, 

 and in the somewhat smaller more glabrate leaves, which in age become 

 distinctly verrucose on the upper surface. 



.Lozanella, n. gen. of Urticaceae (Celtideae). Flowers dioecious. 

 Pistillate flowers in axillary cymes : perianth 5-6-parted ; segments 

 slightly imbricated. Ovary sessile ; style divided to the base, branches 

 stigmatose ; ovules pendulent, solitary. Drupe small, ovoid, compressed ; 

 exocarp succulent; endocarp hard, bony. Embryo curved ; cotyledons 

 oblong^ rotund. Staminate flowers unknown. Ligneous plants with op- 

 posite leaves, axillary cymose flowers, and small greenish drupaceous 

 fruit. 



L. trematoides, n. sp. Stem terete or slightly compressed at the 

 nodes, and as well as the branches covered with a reddish-brown bark,
