46 New Species of South Ambricam Plants 



Pistillate flower solitary in the center of the fascicle, the 

 calyx divided nearly to the base, the lobes ovate, obtuse, 4 mm. 

 long. Glands of the disk very small, adnate to the base of the 

 calyx. Petals sub-setaceous, two-thirds the length of the 

 sepals. Ovary depressed-globose, densely and long brown- 

 tomentose. Styles 5, about 4 mm. long, distinct, shortly 2-fid, 

 the lobes at length recurved. 



Staminate flowers later in developing and smaller, the 

 petals broad, shorter than the sepals, the stamens numerous, the 

 filaments somewhat sinuouS, the anthers oblong, very obtuse 

 or truncate, narrowly white-margined. 



Fruit not seen. 



"A shrubby tree, 8 feet high. A single specimen observed, 

 in second growth at Valparaiso, 4,500 feet. January 18." 

 (Herbert H. Smith, Colombia, No. 1770.) 

 Acalypha salicioides. 



Principal veins of the lower leaf-surfaces somewhat coarse- 

 pilose. Branches rather slender, terete, finely nerved, very 

 leafy. Stipules 4 to 6 mm. long, setaceous. Petioles to 2 cm. 

 long, slender, somewhat angled and nerved. Blades i to 2 dm. 

 long, 4 to 6 cm. broad, lanceolate with blunt base and acuminate 

 and obtuse summit, finely crenate-dentatt when mature, when 

 young bearing minute yellowish cartilaginous teeth, and when 

 very young the margin beautifully and densely beaded by these 

 teeth. Blade thin, deep-green, the venation prominent beneath, 

 slender, whitish, the secondaries about 6 on a side, the lowest 

 pair basal, falcate and then sub-erect, not connecting at the 

 ends, conspicuously connected, by numerous crooked tertiaries. 

 Staminate spikes mostly solitary in the axils, to 6 cm. long, 2 . 

 or 3 mm. thick, sub-sessile, an occasional pistillate flower at 

 their base or in other axils. 



Staminate flowers densely massed, short-pedicelled, the 

 rachis thick, the bracts minute. Sepals 0.5 mm. long, ovate, 

 about as long as the filaments, the anthers large, sub-globose" 

 Dissecting material for pistillate flowers wanting.
