chestnut, about 13 lin. in diam., moneecious, with the outer flowers 
female. Involucral-bracts ? lin. long, }-4 lin. broad, oblong, obtuse 
or acute, entire, very thin and membranous, fuscous, glabrous. Flower- 
ing bracts about } lin. long, lanceolate or spathulate-lanceolate, very 
acute, entire, membranous, fuscous or dull olive-green, glabrous. Re- 
ceptacle glabrous. Female flowers pedicellate. Sepale 2, free, about 
2 lin. long, linear-lanceolate, acute, membranous, fuscous, somewhat 
tessellated, glabrous. Petals none. Stipes between the sepals and 
ovary none or excessively short. Ovary flattened, orbicular in outline, 
glabrous; style divided to about the middle into 2 filiform branches. 
Male flowers pedicellate, glabrous. Sepals 2 or rarely 3, free (always 2), 
about $ lin. long, linear-lanceolate, acute, membranous, fuscous, Stipes 
between the sepals and petals variable, sometimes half as long as the 
sepals. Petals reduced to 3 very minute ovate white segments about 
zo~# lin. long, bearing a black gland at their middle. Stamens 4 or 
6; anthers yellowish.

I do not find that the bracts are lacerate us stated in the original description, 
and it is only the outermost or invyolucral bracts that are sometimes obtuse ; both in 
the type specimen (which Prof. Schinz has kindly allowed me to examine) and in 
the example at Kew they are as described above. I find only 2 sepals present in the 
female flowers, but the male flowers seem to be very variable in the number of their 
parts, some having 2 sepals, 3 petals, and 4 stamens, others 2 sepals, 3 petals and 6 
stamens, whilst a few have 3 sepals, 3 petals and 6 stamens. 
38. E. Stuhlmanni, V. #. Br. <A very small plant. Leaves 
almost capillary. Heads glabrous (probably pale brown). Involucral- 
bracts about as longasthe head. Female flower without petals. Sepals 
unequal, narrowly linear. Male flower with the sepals connate into a 
Spathulate body, trifid at the apex. Anthers white.—Z. sexangulare,

This plant is unhesitatingly referred by Rubland to Z. sewangulare, Linn., but 
that species grows 12-16 in. high and the female flowers have very distinct and 
rather peculiar petals. I have not seen the plant, but think it possible that 
Ruhland made the comparison with Z. sieboldianum, Sieb, & Zucce. (EZ. sexangulare, 
Mart., not of Linn.) to which, from the description, it appears to be closely 
related; but I doubt its identity with that plant. The only African species with 
which it can be compared is E. amboense, Schinz, from which it differs (according 
to the characters given by Ruhland in his key to the species) by the connate sepals 
of the male flowers. 
Imperfectly known species. 
39. E. quinquangulare, Linn. Sp. Pl.87. Koernicke in Linnea, 
XXvii. 642, mentions that there is a specimen of this Indian species in 
the Stockholm herbarium labelled as having been collected by Afzelius 
in Sierra Leone, but that there has probably been some exchange of 
labels.— Durand & Schinz, Conspect. Fl. Afr. v. 503.
