: E. systyloides appears to vary very much in the size and shape of its leaves and 
size and angulation of its seeds. Probably when better known the above varieties 
will be found to grade into each other by a series of intermediate forms so that they 
can scarcely be distinguished from the type by the characters given. The manner in 
which the involucres are peduncled in var. pedunculata seems constant, but I have also. 
seen them with equally long peduncles mingled with the ordinary sessile condition on 
the type. The type specimen of E. Holstii (Holst, 530) and that of HE. Volkensit 
(Volkens, 638) are identical, and have shorter and more lanceolate leaves than in the 
typical ZB, systyloides, but do not otherwise differ, and as there are intermediate 
forms, I do not consider it worth distinguishing as a variety. 
i 2, pseudoholstii, Pax in Engl. Jahrb. xxxiii. 287. Annual, 
with the habit and general appearance of 2. systyloides, Pax. Leaves 
Opposite at the flowering nodes, alternate elsewhere, subsessile, 14-4 in. 
ong, 1-4 lin. broad, linear or linear-lanceolate, acute, tapering to the 
ase, entire or very minutely toothed, with a subulate spreading gland- 
Upped tooth on each side at the base, glabrous on both sides. Stipules 
none or exceedingly minute. Involucres generally 2-3 together in small 
cymules at the tips of the branches, subsessile, ? lin. in diam., cup- 
Shaped, very minutely puberulous, with 4 glands and 4—5 subquadrate 
fringed lobes ; glands 4-} lin. in their greater diam., transverse, oblong 
or subelliptic, Capsule exserted and curved to one side, about 2 lin. 
ong and 14 lin. in diam., oblong, minutely puberulous with curved 
adpressed hairs; styles 3 lin, long, erect, united at the basal part, bifid 
at the apex, with the lobes parallel. Seeds 1} lin. long, dorsally 
flattened, oblong, notched at the base and with a cap-like terminal 
Caruncle, slightly keeled down the back and with 3 grooves down the 
mner face, whitish.

: This is distinguished from E. systyla, Edgew., and E. systyloides, Pax, which are 
euilar in general appearance, by the subsessile leaves, with a subulate tooth on each 
side at their base and by the much smaller, more clustered involucres and different seeds.
