ROSES FROM T 1 1 E SOl'TH - W EST E R N UNITED STATES. 455 



ON TWO NEW BOSES FROM THE SOUTH-WESTERN 

 UNITED STATES. 



By J. G. Baker, F.R.S., V.M.H. 



The two Roses of which I exhibit drawings came from the south- 

 western United States, and have only been discovered lately. Amongst 

 well-known European types their nearest alliance is with R. spinosissima. 

 The following descriptions will show their leading characteristics : — 



Rosa minutifolia. — Engelm. in Bull. Torrey Club, Vol. lx. pp. 97, 

 127 ; S. Wats, in Proceed. Amcr. Acad. Vol. xx. p. 84(5. Stems erect, much 

 branched, two to four feet high ; prickles very unequal, dense, the largest 

 slender and nearly straight, \ inch long, passing down gradually into 

 copious small, slender, straight aciculi. Leaflets usually five, the end one 

 suborbicular, J inch long and broad, deeply incised, firm, nearly glabrous 

 on the upper surface, densely pubescent beneath, with a strong rib 

 running into each tooth ; rhachis pubescent, not glandular ; stipules 

 narrow, adnate, not at all gland-ciliated, with a small deltoid free tip. 

 Flowers solitary ; peduncle short, pubescent, not hispid. Calyx tube 

 small, globose, densely prickly; sepals lanceolate, usually simple, J inch 

 long. Petals bright red, about as long as the sepals. Styles free, 

 villose. Fruit globose, \ inch diameter, crowned with the persistent 

 sepals. (Fig. 127.)

 slender, much branched ; prickles unequal, stramineous, deflexed, nearly 

 straight, the largest ] inch long, with copious aciculi between. Leaflets 

 three, nearly sessile at the apex of the petiole, obovate-cuneate, ^ inch 

 long, firm in texture, deeply toothed at the tip, glabrous on both surfaces ; 

 rhachis glabrous, not at all glandular ; stipules adnate, with a large free 

 tip. Flowers solitary ; peduncle short, not at all hispid. Calyx tube 

 globose, aciculate ; sepals simple, lanceolate, ^ to inch long. Petals 

 bright red, longer than the sepals. Styles hairy. Fruit small, globose, 

 aciculate, crowned with the persistent sepals. (Fig. 128.)
