9. COTULA, Linn. 
Including Leptinella, Cass., and Mykiogyne, Less. 
Herbs, usually perennial, flaccid or succulent, full of minute oil-glands, very 
aromatic when bruised. Stems creeping or prostrate, terete. Leaves rarely 
entire, usually pinnatifid. Scapes short or long, ebracteate or bracteate. — 
Heads small, yellow, subglobular, unisexual, or the outer fl. female, the 
inner male. Involucre of 1 or more series of few or many scales with scari- 
ous margins. Eeceptaele hemispherical or conical, papillose, the exterior 
papillae generally elevated into pedicels for the florets. Florets glandular or 
eglandular ; pappus 0. Male fl. : tubular or funnel-shaped, with minute im- 
perfect aehenes; 4 or 5 loosely cohering stamens, and stout exserted style 
with discoid or bifid stigma. Female fl. : corolla 0, or short or inflated, 
contracted at the unequally 3-5-toothed mouth; style exserted, 2-lobed, 
seated on a spherical disk. Achene compressed, turgid or winged, obtuse 
or 2-lobed, usually thick and spongy. 
A large genus, abounding in many tropical and extratropical countries, especially of the 
southern hemisphere. I have reduced here Leptinella and Myriogyne to it. The species 
are extremely difficult to make out, and better specimens are much wanted.
