the heads, which in fr. resemble little gr. balls stuck full of 
short brown spikes; much as in T. fragiferum L., but with 
the little spikes more numerous or crowded. Pods 2-seeded 
enclosed within the cal. -tube. Seeds tawny-yellow “ovate- 
reniform ” Webb ; radicle prominent.

Smooth bright full gr. ; st .prostrate short mostly buried in the 
soil , the l. alone, and fl. partially, protruding ; lfts. obovate or 
obcimeate sharply and finely toothed upwards, entire below 
the middle ; heads pale gr. irregularly diffusely or indetermi- 
nately globose, axillary dense closely sessile, approximate or 
crowded, often agglomerate or confluent at the base of the stems, 
nearly or quite smooth in all stages, echinulate but not rigid ; 
ti. densely crowded erect sessile; cal. nearly or quite smooth 
10-striate, unchanged in fr., teeth nearly equal or ate- acuminate 
leaf-like 3-nerved not reticulated at the base, falcately spreading 
or recurved often obliquely towards one side ; cor. minute incon- 
spicuous much shorter than the cal. — EB. t. 1049 ; Sm. E. FI.

or Middle Deserta. May, June. — A minute scarcely discern- 
ible inconspicuous pi. with very short stunted st. close-pressed 
to or buried beneath the surface, often leaving only the 1. above 
ground. Boot long slender fibrous. L. -stalks slender filiform 
longer or shorter as the st. are more or less buried in the soil. 
Lfts. small immaculate strongly nerved. Stip. broadly ovate 
acute or shortly pointed. Heads of fl. tufted and mostly irre- 
gularly crowded or confluent in the centre of the pi., like little 
burs or the prickly husks of the Spanish chestnut. Fl. nu- 
merous densely crowded. Cor. pale rose, much shorter than 
the gr. leafy cal. -teeth, which are rather longer and more gra- 
dually acuminate than in T. glomeratum L. and not auricle d 
or cordate at the base. Cal. -tube somewhat feebly striate, 
thin and membranous, sometimes a little hairy, not hardened 
inflated closed or otherwise changed in fr. except in becoming 
ovate. Pods oblong 2-seeded ; “ seeds roundish, radicle promi- 
nent.” (Bab.) Whole pi. often not more than 1-2 in. in diam., 
the st. rarely exceeding 2 or 3 in. in length. The fl. are rather 
aggregate in dense axillary tufts or clusters than in distinct 
determinate globose or. hemispherical heads as in T. glomeratum 
L., with the cor. very small and inconspicuous. 
Bourgeau's Canarian spec, under this name in BII. are by 
some mischance nothing but T. glomeratum L.
