NEW SOUTH AMERICAN ASTERACEAE COLLECTED 
BY E. W. D. HOLWAY 
S. F. BLAKE 
(WITH PLATE XIX) 
The new species of Asteraceae here described form part of a 
collection made by E. W. D. Hotway and Mrs. Mary M. HoLway 
in Ecuador and Bolivia in 1920. A few have previously been found 
by other collectors, notably by J. N. Rosr, who visited a part of 
the same region in 1918. Although Professor Hotway’s interest 
is primarily, in rusts rather than flowering plants, his appreciation 
of the value of precise identification of host plants has resulted in 
the preparation of complete and well dried specimens which have 
considerably increased our knowledge of the phanerogamic flora of 
the regions in which he has collected. Not the least valuable 
result of his work in Central and South America is the discovery of 
many new species of flowering plants, particularly Asteraceae, 
represented by specimens far superior to those of many collectors 
who confine their attention to phanerogams. 
Achyrocline glandulosa, sp. nov.—Perhaps suffrutescent below, 
40 cm. high and more, branched; branches ascending, simple, like 
the stem densely glandular-pubescent, winged throughout by the

on both sides, densely glandular-puberulous, arachnoid-ciliate, tripli- 
nerved; panicles rounded or flattish, 3-7 cm. wide, dense, the heads 
densely glomerate on the branchlets, the glomerules at base loosely 
pilose-tomentose like the branches of inflorescence; involucre 
oblong-cylindric, 4-4.5 mm. high, whitish or pale straw color, the 
phyllaries somewhat graduated, scarious, oblong or elliptic-ovate, 
obtuse, glabrous; ? flowers 4 or 5, % 2; receptacle alveolate; % co- 
rollas tubular-filiform, whitish, glabrous, 4-dentate, 3 mm. long,
