Desert near Gazechah, 2,500 feet ; Lon, 64^50' E., Maynard, 
Hill 8 miles west of Gazechah, 6,000 feet ; Lon. 64^50' E., Wehb-

The specimens of all three gatherings belong obviously to one 
species. Only one gathering, however, that from Amir Chah, has 
flowers and none of them have fruits. All the specimens of each of 
the three gatherings have many of the corky nodes, with the green 
branchlets that spring from these nodes, galled by insects ; these galls 
look so remarkably like flowers that Dr. Maynard^s field-note on the 
Gazechab-desert specimens describes the plant as a bush with rich 
claret-coloured velvety flowers on the branches.” 
The writer finds the same difficulty in dealing with the Afghan 
and Baluch specimens of Calliaonum preserved in the Calcutta Her- 
barium that Dr, Aitchison has found in dealing with those collected 
by him during the Delimitation Commission of 1884-85, The only 
specimen that agrees absolutely with Dr. Maynard^s plant is Griffith's 
95 ijenrnal)^ which was obtained by Griffith in woods at Ja^hun 
not far from Shikarpur, nothing quite like which has been reported 
to Herb, Calcutta, since Griffith collected it, till now. The flowers 
of this plant are less than half the size of those of C, Poiygonoides^ 
the species common in Rajputana and Scinde and extending thence 
into Baluchistan ; the bark, too, and the habit differ materially from 
those either of C, Polygomides or of C, Crinitum Boiss., of which 
latter the flowers are still unknown. The present plant has, how- 
ever, sub-glaucous and striate branchlets as in C, Crinitum^ and the 
writer would not have hesitated to refer it tentatively to C, 
crinitum but for the existence of another Griffithian specimen from 
Afghanistan (K. D. n. 4139), issued as C comomm, which seems to 
agree with our plant and which has fruits quite unlike those of C, 
crinitum. 
Strangely, both of these Griffithian plants {Journal n, 95 from 
Jaghun in Baluchistan and K. D, n. 4139 from Afghanistan) are 
left unaccounted for by Meissner {DC, Prodr, ^ xiv) and by Bois- 
sier {FI Orient,, iv). That the Afghan plant (n. 4139) is not 
C, comosum appears to the writer to be certain ; it accords rather 
with C Caput-Medmx ; if it be the one species or the other, 
it cannot be the same as our plant, which has much smaller flowers 
than either. On the whole the evidence favours the idea that the 
plant represented by Griffith's n, 95 and by Maynard^s specimens
