242 ON SEEDLINGS 



lamina oblong, obtuse, tapering at the base, subfleshy, 6 mm. long, 

 3 mm. wide. 



Stem annual, developed when about to flower. 



Leaves simple, radical (and ultimately cauline), opposite, exsti- 

 pulate, petiolate, glabrous except the petiole, deep green, subfleshy ; 

 petioles channelled above, ciliate on the upper edges, dilated at the 



UBC. 



First pair oblong, pinnatisect with two lateral pairs and a ter- 

 minal segment, all oval or oblong. 



Second pair linear, pinnatisect with numerous oval segments ; 

 terminal one obovate. 



Third pair linear, pinnatisect ; segments small at the base, 

 gradually lengthening towards the apex where they are oblanceolate ; 

 larger ones each with a segment on the posterior basal side. 



Fourth and fifth pairs similar to the last, but rather longer and 

 more equally developed. 



Gilia squarrosa, Hook, et Arn. 



Primary root as in G. crassifolia, colourless but with a few short 

 lateral rootlets. 



Hypocotyl as in G. crassifolia. 



Cotyledons short, linear, obtuse, fleshy, glabrous, 6 mm. long. 



Stem as in G. crassifolia. 



Leaves simple, radical (and ultimately cauline), opposite, exsti- 

 pulate, sessile, glandular-hairy, rather densely aggregated. 



First pair linear, obtuse, fleshy, similar to the cotyledons but 

 longer and glandular-hairy. 



Second pair pinnatifid with two pairs of shortly linear, lateral 

 segments above the middle. 



Third pair similar, or with three pairs of segments. 



Fourth pair linear-oblong in outline, with numerous alternate or 

 eubopposite, linear, slender, aristate segments. 



Fifth pair more or less pinnatisect with pinnatifid segments ; the 

 ultimate segments or secondary lobes arise from the basal posterior 

 side of the primary segments. 



Gilia lutea, Steud. (fig. 528). 



Primary root as in G. crassifolia, with small lateral rootlets. 

 Hypocotyl as in G. crassifolia. 



Cotyledons small, spathulate, obtuse, rather fleshy, 5 mm. long 

 including the petiole, glabrous. 



Stem herbaceous, annual, erect, terete, slender, apparently
