LOWER HIMALAYA ; from Kashmir to Nepal, ascending to 3500ft.; and from 

 the PANJAB to SILHET, the NAGA HILLS, alt. 5-8000 ft., and BURMA. TheCiRCARS, 

 NILGHIRI, and KURG HILLS. DISTRIB. Westward to Europe, N. Africa, N. Asia. 



Stem 6-10 ft., tistnlar. Leaves 1-2 ft., tapering from the base to the apex, 

 smooth, bifarious, drooping ; lignle a ridge of hairs. Panicle 1-2 ft., branches 

 scaberulous, erect or drooping. Spikelets in., green or yellowish ; gls. I and II 

 acute or obtuse and apiculate. A curious branched small-leaved apparently dwarf 

 form named A. b ambus if olia, mss., was collected by Griffith on the summit of 

 Thumathaya (Mishmi Mts.),and is alluded to in his Journals, p. 45, as " an Arundo 

 festucoidea." Gri:>ebach (in Goett. Nachr. (1868) 76) describes a form of A. Pliniana, 

 Turra, with the mouth of the sheath ciliate, as a native of the Himalaya (Simla, 

 alt. 3-9000 ft.). The above character is found in Indian specimens of what I cannot 

 distinguish from A. Donax. A. Pliniana appears to Dr. Stapf and myself to be a 

 mere form of Donax with smaller spikelets, wlrich organs in Indian specimens vary 

 from - in. The plants with the smaller spikelets are, I presume, the A. mauri- 

 tanicct, Poir. (a synonym of Pliniana} of Duthie Grass. N.W.Ind. 35, Fodd. Grass.
