486 ON SEEDLINGS 



No. 4. Cordate elongated, lob ulate but scarcely pinnatifid, coarsely 

 serrate with mucronate serratures, palmately five-nerved. 



Ultimate leaves simple, palmately five- to seven-lobed and -nerved, 

 cordate at the base, closely covered with bulbous-rooted hairs ; lobes 

 deltoid, acute or obtuse and more or less rounded, acutely and more 

 or less doubly serrate. 



Geum Freemontii, Hart. (fig. 313). 



Primary root slender, tapering, brownish, with fibrous lateral 

 rootlets, perennial. 



Hypocotyl tapering, whitish, glandular-hairy, 4 mm. long. 

 Cotyledons small, glandular-pubescent, lamina 2'7o mm, long, 

 2 mm. broad ; petiole 2*5 mm. long, dilated and sheathing at the base. 

 Stem herbaceous. 



Leaves radical, simple, ultimately imparipinnate, alternate, stipu- 

 late, petiolate, glandular-hairy with hairs of very unequal length ; 

 petioles slender, channelled above, and sheathing by means of the 

 stipules ; stipules wholly adnate to the petiole by 

 one side. 



No. 1. Reniforrn, palmately five-nerved, with 

 rounded or obtuse teeth. 



No. 2. Rotund-cordate, palmately seven-nerved 

 and -fid, with suboval, mucronate lobes. 



No. 3. Cordate, pahnately seven-nerved and -fid, 

 with oblong-ovate, mucronate lobes. 



Ultimate leaves imparipinnate, oblanceolate 

 in outline, hairy on both sides, light green above,

Nat. size. occasional minute, lanceolate, entire ones niter- 



posed, deeply incise-serrate, cut or subpinnati- 

 fid especiaUy on the basal posterior side, with alternate, strong 

 nerves running into the lobes and teeth ; terminal leaflet elliptic ; 

 the pair below that obliquely ovate, cut away on the anterior basal 

 side ; below this the leaflets are ovate, then rotund-ovate, gradually 

 becoming rotund and cuneate at the base ; petiole semiterete, chan- 

 nelled on the upper side ; stipules hyaline, ciliate, adnate to the 

 petiole, with ovate, acute, free points. 



The cotyledons of G. urbanum resemble those of G. Freemontii. 



Geum coccineum, Sibth. et Sm. 



Primary root and hypocotyl very similar to those of last species,
