mericarps could eventually be strongly dorsally compressed; but it may well be so, for 
Ferula ($ Huryangium) Sumbul, Hook. f., exhibits this peculiarity in a marked degree, 
and our plant is clearly allied to it, though readily distinguished by the much larger 
and broader segments of the leaves, and the verticillate branching of the inflorescence.

Hari-rud valley: 422, Мау 10, June 6, July 26, 27, 1885. Native name Kandal- 
kema, Ushak. Опе of the characteristic plants of the country, which it covers in some 
places to such an extent that on looking round one can see nothing else, and no 
limit to it. The radical leaves are very large and very similar to those of Ferula 
fetida, Regel; and both plants on being injured yield a milky juice before the flower- 
stem is thrown up. Without the aid of smell, it was almost impossible to tell which 
plant one was looking at. However, the moment the plant begins to throw up its stem, 
there can be no doubt as to the genus. Unlike many species of Ferula, the inflores- 
cence of the species of the present genus is unprotected by stipular expansions or 
foliaceous bracts. Мо sooner is the fruit well formed and beginning to ripen than the 
plant is attacked by some boring insect, which causes the milky juice to escape. This 
dries into hard blocks, frequently enclosing the fruit. The Kandal, Ushak or Ammoniacum 
is usually collected from the stem and frutescence, and often encloses clusters of the fruit. 
A large series of sections was made of different earpels, and at all heights, but only 
faint traces of vittee were observed, and these occurred irregularly; yet Borszezow 
(Ferula, t. 5) figures them comparatively wide.

Badghis: 462, May 14, 16, 1885. Native name Kema-i-asp. А gigantic plant grow- 
ing in the beds of dried-up water-courses and forming a thicket with Tamarisk. Тһе 
enormous pyramidal panicle covered with soft balls of brilliant yellow flowers could 
only be likened to Acacia arabica when in its full glory of inflorescence. 16 yields a 
yellow gum resin, but I did not hear ofthis being collected. As a rule all the outer 
flowers on the stems are male, those closer to the main stem being female; and it is 
the male flowers that make the great show in the inflorescence.
