ROSACES 485 



Leaves at first simple, ultimately trifoliolate, cauline, alternate, 

 stipulate, petiolate, glandular-hairy on both surfaces, felted beneath 

 with a white tomentum, penninerved with alternate or subopposite 

 nerves ; petioles semiterete, channelled above, densely glandular- 

 hairy and glandular- setose, the hairs and setae of a reddish-purple 

 hue ; stipules slender, subulate, attenuate, glandular-hairy. 



No. 1. Small, ovate, tridentate, trinerved. 



No. 2. Eeniform, five-nerved, dentate. 



No. 3. Kotund-cordate, obtuse, irregularly dentate. 



No. 4. Cordate, irregularly or doubly dentate.

Ultimate leaves pinnately trifoliolate, pubescent and dark green 

 above, felted with white tomentum beneath, glandular-hairy and 

 setose on the principal nerves ; terminal leaflet very large, rotund- 

 cordate, acuminate, trifid and doubly dentate-serrate, strongly penni- 

 nerved, much reticulate with the stronger nerves running into the 

 lobes or large teeth ; lateral leaflets broadly ovate, subacuminate, 

 deeply dentate-serrate, oblique on the posterior side, smaller but 

 otherwise like the terminal one, rather unequal but not cordate 

 at the base. 



Leaves on the flowering branches similar to the above, but gra- 

 dually becoming smaller in size as the inflorescence is approached ; 

 petioles terete, very narrowly channelled on the upper side, densely 

 glandular-hairy and setose ; stipules subulate or linear, attenuate, 

 slender, shortly adnate to the petioles. 



Rubus rugosus, Sm. 



Primary root tapering, slender, soon becoming wiry, and giving

 veloped ; 2nd 1-5 mm. long ; 3rd 6' 5 mm. ; 4th 3 mm.
