UMBELLIFER^E 37 



at the base, connate and sheathing the plumule for 7-8'5 mm. at 

 the base, and often splitting there on one side. 



Stem herbaceous, forming a perennial rootstock, and sending up 

 annual flowering stems ; primary internodes undeveloped. 



Leaves pinnately multisect, chiefly radical, the cauline smaller, 

 alternate, exstipulate, petiolate, with a venation corresponding to 

 the divisions of the leaf, each segment of which has a primary nerve, 

 glabrous, shining on both surfaces, deep green above, paler beneath ; 

 petiole subterete, or laterally compressed, shallowly channelled 

 above, thicker dorso-ventrally than in the other direction, glabrous, 

 covered with a glaucous bloom, striated longitudinally, dilated and 

 sheathing at the base. 



No. 1. Pinnately tri- or slightly quadri-sect with the ultimate 

 divisions subulate or linear, acute, with colourless tips. 



Ferula foetida, Bunge. 



Primary root as in last species. 



Hypocotyl undeveloped. 



Cotyledons linear-lanceolate, obtuse, entire, gradually tapering 

 into the long petiole, glabrous, shining on both surfaces, deep green 

 above, paler beneath, with a distinct midrib but no other discern- 

 ible venation in the fresh state, about 14 em. long including the 

 petiole, and 6 mm. wide about the middle of the lamina ; petioles 

 semiterete, flattened above, with obtuse edges connate for 8-10 mm. 

 at the base, forming a sheath around the plumule and afterwards 

 splitting on one side, glabrous, green, stained with red. 



Stem herbaceous, perennial, developing in length only when about 

 to flower ; primary internodes undeveloped. 



Leaves simple, radical and cauline, alternate, exstipulate, petio- 

 late, alternately and ascendingly penninerved, reticulate, glabrous 

 except the petioles, deep green above, paler beneath, shining on both 

 surfaces ; petiole subterete, slightly flattened on the upper side, or 

 subchannelled towards the apex, dilated and sheathing at the base, 

 minutely and thinly pubescent, at least in the young state. 



No. 1. Triangular, tripartite, with a long petiole; terminal lobe 

 rhomboid-cuneate, trifid and serrate above the middle or towards 

 the apex; lateral lobes spathulate-cuneate, serrate towards the apex. 



No. 2. Similar, but having the lateral lobes broader and some- 

 what bifid. 



Peucedanum sativum, L. 



Primary root fleshy, or stout, tapering, colourless, with lateral 

 fibres.
