RANUNCULACE/E 97 



Hypocotyl very short or suppressed, or indistinguishable from 

 the root or together with the latter becoming fleshy, tapering 

 downwards and forming the persistent rootstock of the plant. 



Cotyledons ovate, acute, mucronate, five- 

 to seven-nerved longitudinally, glabrous, pale 

 green, connate by their bases and forming a 

 little cup ; petioles terete, erect, slender at the 

 base and split on one side to allow the escape 

 of the plumule, glabrous, pale green, 2-8 cm. 

 long, connate through their whole length ; 

 lamina 6-12 mm. long, 3'5-9-5 broad. 



Stem herbaceous, erect, twelve to eighteen 

 inches long, elongating when about to flower ; 

 primary internodes undeveloped. 



Leaves simple, palmately lobed, radical and 

 cauline, alternate, exstipulate, palmati-nerved, 

 bright green above, paler beneath, shining on FIG. 137. Delphinium 

 both surfaces, petiolate ; petiole terete, slightly ^ caule - Half nat. 

 flattened on the upper side, or channelled to- 

 wards the apex, somewhat dilated at the base and sheathing, pale 

 green, glabrous. 



No. 1. Palmately three- to five-fid, five- to seven-nerved, lobes 

 generally cuspidate, teeth tipped with a glandular mucro. 



Delphinium trollifolium has the petioles of the cotyledons united 

 in the same way as D. nudicaule. 



Delphinium Consolida, L. 



Primary root similar to D. Staphysagria. 



Hypocotyl erect, terete, glabrous, pale greenish-white or stained 

 with red, tapering insensibly into the root, protruding 8-12 mm. 

 above the soil. 



Cotyledons broadly oblong-ovate, obtuse, entire, tipped with a 

 pale-coloured mucro, glabrous, obscurely trinerved with the lateral 

 nerves much branched, anastomosing, incurved and uniting with 

 the midrib close to the apex, petiolate ; petioles grooved above, 

 convex on the back, dilated and connate at the base, 9'5-12 mm. 

 long ; lamina 12-13'5 mm. long, 7-9 mm. wide. 



Stem herbaceous, annual, elongating when about to flower ; 

 primary internodes undeveloped. 



Leaves simple, radical and cauline, alternate, exstipulate, tri-par- 

 tite or -sect, with the venation ramifying accordingly, and obscurely 

 reticulate, pubescent on both surfaces when young, glabrescent,
