UMBELLIFEE.E 27 



Seedling. 



Primary root long, tapering downwards, more or less flexuose , 

 with a few lateral rootlets, colourless, annual. 



Hypocotyl erect, terete, thinly hairy, and densely covered with 

 small, elevated, gland-like points, deep red, tapering insensibly into 

 the root, 2'4-2'S cm. long. 



Cotyledons oblong-spathulate, petiolate, obtuse, minutely emar- 

 ginate, with a distinct midrib, alternately trinerved from the 

 middle upwards, but the nerves only visible on the under side, 

 densely pubescent, and more or less glandular on both surfaces, 

 dull green above, paler beneath or stained with red ; lamina 9*5-11 

 mm. long, 5 '5-7 mm. wide, tapered into the petiole ; petiole grooved 

 above, convex on the back, connate at the base, pubescent and 

 more or less glandular, 6*5-7'5 mm. long. 



Stem herbaceous, annual, erect, terete, branching and flexuose, 

 or zigzag, densely glandular-hairy ; 1st and 2nd internodes un- 

 developed ; 3rd -5 mm. long ; 4th 3-4 mm. ; 5th 1-8-2-2 cm. 



Leaves simple, tri-fid, -lobed or -sect, cauline, or the first two 

 radical, alternate, exstipulate, petiolate, palmately trinerved from 

 the base, glandular-hairy on both surfaces, deep green above 

 and shining, much paler beneath ; petiole semiterete, channelled 

 above, glandular-hairy, tapering upwards from a broadish, semi- 

 amplexicaul base. 



No. 1. Cuneate, trifid ; segments short, oblong, minutely cuspid- 

 ate, obtuse. 



No. 2. Broadly cuneate, trifid ; middle segment oblong, obtuse 

 minutely cuspidate ; lateral segments oblong, bidentate at the apex ; 

 apices minutely cuspidate. 



No. 3. Palmately tripartite ; middle segment spathulate-cuneate, 

 tridentate at apex ; lateral segments obliquely cuneate and un- 

 equally trifid. 



No. 4. Palmately tripartite ; middle segment spathulate-cuneate, 

 trifid and slightly dentate ; lateral segments cuneate, unequally 

 trifid, and slightly dentate. 



Nos. 5 and 6. Deeply tripartite, with narrower segments than 

 the fourth. 



The specimens after this were showing flower, while the leaves 

 gradually became reduced, palmately tripartite, with linear, trifid, 

 or tridentate or entire segments. 



Like its congener, T. pusilla, it resembles a species of Saxifrage. 



Eryngium paniculatum, Cav. (fig. 407). 

 Hypocotyl subterranean.
