130 BOTANY OF BALUCH-AFGHAN BOUNDARY COMMISSION, l8gS* 
Between Goari Nullah and Bara Khan Karez ; Lon. 66®io' F.; 
leaves galled, Maynard» Gargarok, 4,500 feet; -Lon. 64^45' E.^ 
Maynard, 
This tree was found by Dr. Maynard growing in clefts of lime- 
stone rock above the level of the tamarisk {Tamar ix macrocar pa) 
that filled the bottom of the valley. In this place therefore the 
species affects a position corresponding tc that affected (see Lace and 
Hemsley) by Pistacia Khinjak in the Quetta district. Dr. Maynard's 
tree is, however, undoubtedly P. cahulica^ which Messrs. Lace and 
Hemsley treat as only a variety of P mutica. Dr. Aitchison goes 
still further, since he will not admit that even P. Khinjak can be 
Separated from P. mutica, and further believes that, when so united, 
P. mutica^ Khinjak and cahulica only form a variety of P. Terehin- 
thus, A careful examination of the material in the Calcutta Herba- 
riujja prevents the writer from adopting Aitchison’s conclusion and 
leads him, with Stocks and Boissier, to treat P, cahulica as a distinct-— 
it certainly is a very easily distinguishable — plant, 
LEGUMINOS2E. 
10. Astragalus squarrosus Bunge. FL Orient., ii, 437, 
Saindak, 3,000 feet ; Lon, 6 i°4o' E., Maynard, 
The specimens exactly agree with Griffith’s n. 1541 [K. D.] and 
with Stocks' n. 761. This species forms, at all events in part, the 
A.hyrcanusoi Messrs. Lace and Hemsiey’s list. Though it super- 
ficially closely resembles A, hyrcanus it is in reality very distinct 
from Pallas’ plant. 
UMBELLIFER^. 
11. Trachydium Kotschyi Boiss, FL Orient,^ ii, 929. 
Near Robat, 5,000 feet; Lon. Maynard. Near Sain- 
dak, 3,000 feet, in an almost dry stony river-bed ; Lon. 6i®4o‘ E., 
Maynard. 
Flowers paie greenish-yellow, smelling exactly like parsley. 
12. Ferula Assa-fcetida Linn. FI. Orient., ii, 994. 
Hills between Samuli and Robat, 5,000 feet; Lon. 63^50' E., 
Maynard, 
The t^ue Assa-fcetida or at all events one of the species from 
which Assa-toetida is collected ; seen again at Amir Chah, Lon. 
,62^35' E., and at Saindak, Lon. 61^40' E, The plant affects bare 
rocky hill-sides and m trying to dig out an entire rhizome, holes 
several feet deep were frequently made ; an entire root- stock was, 
however, never obtained.
