6. E. tunariense (Hieron.), comb. nov. Shrubby, 1 m. high; 
copious'y branched above; branches opposite, ascending, terete, 
densely and somewhat fulvously sordid-pubescent, the hairs short, 
transparent, incurved, attenuate, jointed; leaves opposite, ovate,

somewhat attenuate at the apex, more abruptly acuminate at the 
short-petioled base, 2-4-toothed on each side or sometimes merely 
undulate or subentire, dull green, sparingly pubescent but decidedly 
scabrous above, paler and somewhat densely sordid-pilose beneath, 3- 
nerved either from the base or from a point somewhat above the base; 
heads numerous in dense terminal compound leafy-bracted flattish 
corymbs, 20-30-flowered, about 1 cm. long, 3-4 mm. thick; involu-

This species cannot be satisfactorily included in E. odoratum ii, 
which as to its Jamaican type, has longer-petioled leaves, never sca- 
brous above, smaller heads, narrower green-maculate involucral 
it would be impossible to exclude many ot t 
which would be highly unsatisfactory. Under these circumstances 
it appears the practical course to treat E. tunariense for the present 
as an independent species. 
7. EB. Arnottianum Griseb. Nearly or quite herbaceous, essen- 
tially erect, 4 dm. or more in height, finely grayish-puberulent, not

tenuate entire base, 3-nerved, submembranaceous, 5-7.9 cm. long,
