TROPICAL AMERICAN EUPATORIEAE 77 
E. conyzorwes Vahl, var. cintatum (Hook. & Arn.) Hieron. in 
Engl. Bot. Jahrb. xxii. 741 (1897), as ciliata; R. E. Fries, Ark. for 
Bot. v. no. 13, 8 (1906), also as ciliata. E. ciliatum Hook. & Arn. 
Comp. Bot. Mag. i. 240 (1836), not Less. EF. Hookerianum Griseb. 
Pl. Lorentz. 118 (1874).—This, as yet rather obscure, plant was re- 
ported by Hieronymus, I. c., as having been collected at various 
stations in northern Argentina, and also on the Cuesta de Aguay- 
renda between Itaperenda and Yucaiva in southwestern Bolivia, 
and by Fries, |. ¢., in shade of bushy places at Tarija. The writer 
has not had an opportunity to examine any material of the plant in 
question. Baker in Mart. Fl. Bras. vi. pt. 2, 277 (1876) reduces it 
without comment to the synonymy of EF. conyzoides Vahl. Hierony- 
mus, |. ¢., states that it differs from FE. conyzoides, var. Maximiliani 
(Schrad.) Bak. chiefly by having the leaves long-cuneate at the base 
and with the lowest pair of lateral nerves arising somewhat above the 
base of the blade. He also states that the florets vary from 20 to 30, 
and that the mature involucre is 8-9 mm. long, the scales being green at 
the tip and distinctly ciliate. Should this plant prove separable as a 
distinct species—which from its trifling characters seems rather 
unlikely—it may bear the name E. Hookerianum Griseb. If, however, 
as is much more probable, it proves only a varietal phase or tendency 
of E. odoratum or some other of the already rather numerous and 
very closely related species and varieties of this perplexing affinity, 
it is clear that it will have to be renamed, since E. conyzoides Vahl is 
certainly an invalid name. Without access to either the type material 
of E. cilatum Hook. & Arn. or to any Bolivian specimen identified 
with it, the writer must defer any attempt to pass critically upon this 
plant. 
E. conyzoides, var. tunariense Hieron. in Engl. Bot. Jahrb. xxii. 
742 (1897) as tunariensis = E. TUNARIENSE (Hieron.) Robinson 
. (see p. 39). 
E. dumosum Sch.-Bip. Bull. Soc. Bot. Fr. xii. 81 (1865-66), where 
the description is confined to the expression “ (fol. subintegr.)”’; 
also in Linnaea, xxxiv. 535 (1865-66), where the heads are stated to 
be 39-flowered. It is said that this species, mixed with E. Sternberg- 
ianum DC., was distributed as Mandon’s no. 254. Of this number 
two sheets (Gr. and N. Y.) have been examined but on neither has 
any mixture of material been found. The plants on both have 
conspicuously crenate-serrate leaves and heads about 25-flowered as 
in E. Sternbergianum, to which they appear to be correctly referred. 
E. dumosum Sch.-Bip. is too slightly described to have any claim as 
a valid species even if it is as yet impossible to reduce it to synonymy.
