Atriplex (Chenopodiaceae). , 
At Kew, I examined two species of this genus, viz., A, Halimus, 
L., and A, Nuttalii,S.Wats., and found saponin in the leaves of both, 
especially in the last-named species. At Haarlem, I had at my 
disposal seeds of A. hortensis, L., A. laciniata, L., A. rosea, L., 
A, tatarica, L. and A, vesicaria, Hew., and found much saponin in 
all; the haemolysis by an extract of the seeds is moderately great, 
1-250 to 1-750. 
Atriplex is new as a saponin plant; in the same order only 
Chenopodium mexicanum, Mog., was known to contain saponin. We 
may remember, for instance, that the foliage of A, hortensis, L., is 
used as a diuretic, the seed as an emetic, which is quite plausible 
on account of the saponin-content. In China, a skin disease occurs 
“atriplicismus ” caused by a poisonous species of Atriplex ? 
Buddleia (Loganiaceae). 
The leaves of B. globosa, Hope, contain saponin. Seeds of 
B. Lindleyana, Fort., examined at aarlem, gave an extract 
containing saponin, which frothed at a dilution of 1-500 and 
haemolysed at 1-800. There is also a little saponin in the seeds of 
B. variabilis, Hemsl. It is known that the leaves of B. madagascart- 
ensis, Liam., are used as a soap substitute, the twigs 0 DB. 
brasiliensis, Jacq., B. curviflora, Hook. et Arn., and B. verticil- 
lata, H.B. et K., as a fish poison and other species as taenifuge or 
vermifuge, and also as diuretic and expectorant. 
Callicoma (Saxifragaceae), 
The leaves of C. serratifolia, Andr., contain saponin, but not in 
large quantity. 
Calophyllum (Guttiferae). 
The leaves of C. Calaba, Jacq., contain saponin. Poisonous 
esiogs are not unknown in this genus ; some e.g., C. Inophyllum, 
. and C. montanum, Vieill., are used as fish poisons. 
Canella (Canellaceae).

of these plants for the cyanogenetic principle, but the material for 
this is not obtainable in Europe. The statement of A. Stahl (1884) 
thus becomes clear, according to which in Porto Rico, twigs of 
- alba, Murr., are thrown on the water to narcotise fish in order 
that they may be easily caught. 
Cassia (Leguminosae-C aesalpineae), . 
The leaves and also the seeds of C. marylandica, L., contam

In Cassia there are a number of data which point to the presence of 
saponin (¢.g., the employment of some as fish poison, of others as
