TURNERACE^. 

 Named by R. A. Rolfe. 



Tiirnera nerTOsa, Urban, Mon. Turn., 108. 



Caballero (609). January. 



A shrubby plant from 15 to 20 cm. high. Silky hairy on the in- 

 florescence, especially on the flower buds, and smooth on the stem 

 below. The floral leaves or foliaceous bracts are immediately below 

 the flowers, so that the flowers appear without the adnate peduncle 

 common to the genus. The cup-shaped glands large and conspicu- 

 ous. A very delicate, large, light-purple corolla, 2 cm. long. Leaves 

 oblong, glabrous above, pubescent on the midrib beneath, serrate 

 above, the largest 3 cm. long and 1 cm. wide, biglandular at base. 

 Petioles scarcely none. All the species and varieties here enumer- 

 ated grow in dry soil, and have hard tough roots. All have some- 

 what vermiform, whitish or brownish pitted seeds. 



Tiirnera Ulmifolia, L., var. cuneiformis (Poir.), Urban, Mon. Turn., 

 138. 



Caballero (608). January. 



About as high as no. 609. Stem and leaves covered with long 

 white or fuscous appressed hairs. Leaves oval, crenate-dentate, 

 cuneiform at base, 2-4 cm. long, 1-2 cm. broad. Petioles 3-7 mm. 

 long, white tomentose beneath and darker above. Flow^ers large, 

 light yellowish-purple. 



Tiirnera ulmifolia, L., var. elegans (Otto), Urban, Mon. Turn., 139. 



Asuncion (222). December-January. 



Stems very hairy with white appressed hairs, 2-3 dm. or more 

 high. Leaves ovate or ovate-lanceolate, with large serrate teeth, 

 the blades 3-6 cm. long, 1-2 cm. wide, biglandular at base, sloping 

 into a petiole about 1 cm. long. Flowers large and showy, violet- 

 colored, with a deep purple base inside, radiating on the petals above 

 in lighter purple and yellowish lines. The corolla spreads wide 

 open, about an inch in diameter. This plant is very abundant on 

 the railroad track near Asuncion. I always found it inhabited by 

 large black ants which resented disturbance.
