Piper — Andropogon halepensis and Andropogon sorghum. 29 



(A. miliaceus Roxb. ) the other with the sessile spikelets 5 to ^ inch long 

 (A. laxus Roxb.) 



The followino; specimens are all in the herbarium at Kew: Chenab 

 River, Punjab, Thompson, Nov. 1846; India, Herb. Wight, No. 1673; 

 Punjab, T/ioOTpson/Mehannddee, below Muldah, Hooker and Thompson, 

 11 I 5 I 50; Afghanistan, Bolan Pass, Griffith; Khoondas, Nilgiri Hills, 

 Hohenacker, No. 1284; Howrah, /. D. Naske, No. 1317; Monghyr, 

 Mekim, No. 1402; Assam, Fielding ; Kashmir, V. Jacquemont, No. 6561; 

 H. I. No. 8778. 



Under cultivation at Arlington, Farm, Va., this grows to a much 

 greater size than A. halepensis (genuinus) and differs conspicuously in 

 its larger looser panicles. The rootstocks are extraordinarily abundant, 

 short and thick, forming a dense tangled mass. 



The cultures of this subspecies were from seed collected by A. C. Hart- 

 less at Saharanpur, India. 



Andropogon halepensis muticus Hack, in DC. Monogr. Phan. 



6:502. 1889. 



Awns wanting, otherwise as in A. halepensis miliformis. 



Hackel included under the name A. halepensis muticus both the plant 

 here considered and A. halepensis anatherus. His references are however 

 primarily to the awnless plant of India. 



The following specimens are in the herbarium at Kew : Ceylon, Thwaites 



No. 2484; Herb. Griffiths No. 6825; Chumba 3000 ft. alt. C. B. 



Clarke; Rawul Pindee, /. E. T. Aitchison No. 116, Aug. 1870; Kumaon, 

 Strachey & Winterbottom No. 2; Nahan, V. Jacquemont No. 2518; 

 Mustafabad, Punjab, r/iomson;Bhyrowal, 45 mi. east of Lahore, Thomson? 

 No. 1542 ; Timmoo Ghat, Thomson, Oct. 1846. 



This plant was apparently confused by Hackel with propinquus also, as 

 under the latter name he cites a specimen from Ceylon collected by 

 Trimen. Specimens grown in the Botanic Garden at Durban, Natal, /. 

 Medley Wood, Nos. 6000 and 6675 (Kew) clearly belong here; one col- 

 lected in Abyssinia by Figari is apparently the same. 



Andropogon halepensis propinquus (Kunth) Hack. 



Andropogon affinis J. S. Presl in C. B. Presl Rel. Haenk. 1:343. 1830. 



Specimen from Luzon. 

 Andropogon propinquus Kunth Enum. 1:502. 1833. Change of name due

1889. 



Perennial, but producing only a few stout rootstocks, 15 to 30 cm. long, 

 sometimes 1 cm. in diameter; culms several to many, stout, 2-3 or under 

 cultivation 5 meters high, and 0.5-3 cm. in diameter; nodes 15-26; leaf 

 blades 3-5 cm. broad, 30-100 cm. long, sparsely appressed-pubescent at 

 the collar, and loosely pubescent on the swellings at the base above; 

 ligule very ciliate; panicle large, densely flowered, 20-60 cm. long, the
