equal subulate in fruit spreading very rigid 1 -nerved, leaflets 
obcordate serrulate, stipules ovate-cuspidate, stems procumbent. 
E. B. t. 903. 
Chalky or dry sandy fields near the sea, on the east coast to Kin- 
cardineshire, on the west to Anglesea. ©. 5 — 7. — A small spread- 
ing plant with many terminal and axillary, sessile, ovate heads, very 
rigid in fruit. Leaflets with the veins thicker and curved near the 
margin. 
f f Throat of the calyx naked. 
12. T. glomerdtum L. ( smooth round-headed T.) ; heads ter- 
minal and axillary sessile globose, calyx-teeth ovate very acute 
leafy veiny at length reflexed, leaflets obcordate toothed, sti- 
pules ovate much acuminated, stems procumbent. E. B. t. 
1063. 
Gravelly heaths and pastures in the east and south of England. 
0. 6. — Similar to the last, but with rounder heads, and broader, 
greener, and more foliaceous and spreading teeth to the calyx. 
13. T. strictum L. ( upright round-headed T.) ; glabrous, heads 
terminal and axillary stalked globose, calyx at length carnpa- 
nulate with nearly equal subulate spreading teeth, leaflets 
elliptic lanceolate denticulate, stipules rhomboid pointless den- 
ticulate, stems erect. E. B. S. t. 2949. 
Rocky banks near the sea, rare. Landewednack, and Old Lizard 
Head, Cornwall. Jersey. 0. G, 7 .— Stem 2 — 3 inches high in British 
specimens, often 6 — 10 inches in foreign ones. Leaves glabrous, beauti- 
fully striate and toothed, lower ones obovate. Stipules large, pointless, 
with glandular teeth. Heads with a minute membranous cup-shaped 
involucre at their base ; bracteoles none at the base of the flowers. 
Flowers never truly deflexed as in the foreign T. parviflorum, although 
by the ripening of the fruit the lower ones sometimes appear so. 
14. T. suffocatum L. ( suffocated T.) ; heads sessile roundish, 
petals shorter than the membranaceous faintly striate calyx 
whose teeth are broadly subulate falcate recurved. E. B. t. 
1049. 
Sandy sea-shores, rare. On the coasts of Norfolk and Suffolk, 
Anglesea and the south of England. ©. 6, 7. — Stems 3 — 4 inches 
long. Remarkable for its dense sessile heads of inconspicuous flowers 
and for its thin, delicate, scarcely striate calyx. Whole plant glabrous, 
unless T. congestum Guss. be considered a variety. 
15. T. subterrdneum L. ( subterranean T.) ; heads lateral 
stalked hairy of few flowers, at length deflexed and throwing 
out from their centre thick fibres palmated at the extremity 
(abortive calyces) which are closely bent down over the re- 
flexed fruit. E. B. t. 1048. 
Dry gravelly pastures in England. ©. 5, 6. — Stem 3—6 or 8
