T. brevipes differs from T. obscura in its smoother scarcely 
scabrous less straggling or divaricate branches, more cut and 
divided 1. without a conspicuously large and drooping elongated 
terminal 1ft., and in the smaller lateral short-stalked umbels. 
Approaching T. tenuifolia in foliage, it is at once distinguished 
by the short-stalked lateral umbels, small fl. and long slender 
styles. 
4. T. nodosa (L.). 
Strigose ; st. procumbent decumbent or diffuse, remotely 
forked ; 1. finely 2-3-pinnate, lfts. regularly and evenly inciso- 
pinnatifid, the segm. parallel narrow linear-lanceolate acute en- 
tire ; umbels nearly or quite sessile lateral 2- or 3-rayed small 
and dense without gen. inv. ; styles in fl. very short, in fr. about 
half the length of the bristles ; fr. partly bristly partly waited.

fields and fallow ground to the W. of Funchal between the Rib. 
Seco and Praia Formosa. PS. cornfields up Pico Branco and 
P. do Facho. March, April. — An inconspicuous pi. of humble 
growth, at first tufted, afterwards with weak spreading branches 
6-12 in. long from the crown of the fibrous root, widely forked 
slender but stiff* and rigid, straggling, minutely strigulose, some- 
times nearly smooth, often purplish. L. harshly substrigose dark 
y.-gr., their ultimate segm. very regular and uniform narrow- 
oblong or sublanceolate acute. Umbels either sessile or with very 
short stout ped. 1-2 lines long, very small globosely capitate 
dense confusedly and obscurely 2- or 3-rayed, rays very short. 
Gen. inv. 0; partial many longer than the pedicels. Fl. minute 
regular crowded, always w. in Mad. Styles in fl. excessively 
short, scarcely longer than the stylopod. Fr. globosely agglo- 
merate rather large oval or ovate heteromorphous i. e. bur- 
like and bristly or warted ; sometimes both mericarps entirely, 
sometimes only the outer one, or the exposed outer part of one 
or both, in the outer row of fr. clothed with very rough or sca- 
brous, whitish scarcely glochidiate bristles twice the length of 
the inconspicuous styles and mostly but not always exceeding 
in length the breadth of the fr. ; the inner fr. wholly and the 
inner parts merely of the outer fr. granulate or warted. 
T. nodosa WB. ii. 166, 167 seems to be composed of two dis- 
tinct sp. or at least remarkable varr., T. nodosa (L.) and T. in- 
festa Bourg. PI. Can. no. 821 in B1I.
