limited here, this is one of the most widespread weeds in the world. The following 

 varieties (among many others) have been esteemed species : 



' Var. 1. ANNTJA (sp.) Roem 8f Sch. ; umbel with fe\v (often with 3-1) ellipsoid 

 obtuse spikelets. Common in Europe, rare in Bengal. 



Var. 2. DEPAUPEEATA (sp.) Br. ; stems very slender, flaccid, with few spikelets 

 C. B. Clarke (n. 44119) from Assam, has a long slender stem, with a single lateral 

 spikelet, overtopped by most slender leaves ; recedes from the type F. diphylla more 

 than does the Australian jp. depauperata. 



Var. 3. PLURISTRIATA, var. C. B. Clarke (F. pilosa of most authors not of 

 Vahl) ; sheaths and leaves often hairy, nut 10-16-striate on each face often 

 verrucose or tubercular on shoulders. A very common southern, especially Malay 

 form. 



Var. 4; SPIROSTACHYS (sp.) F. Nuell. ; large, umbel large, spikelets large. 

 In Australia ; but a Khasia form is equally large. 



Var. NILAGIRICA ; rhizome very short, creeping ; stems 12 in. in a close linear 

 series ; leaves filiform. Perhaps referable to F. stolonlfera. Nilghiri Hills, Pykara, 

 King. 



16. -F. stolonifera, C. B. Clarke ; stoloniferous, spikelets dark 

 chestnut, otherwise as F. diphylla. Fimbristylis, Wall. Gat. 3503, A, B 

 (part] C. 



KHASIA HILLS, alt. 2-5600 ft., common. MUNEYPOOR ; Watt. NEPAL or 

 BENGAL; Wallich. 



Stolon breaking out horizontally from the base of stem, hardening into a long 

 wiry rhizome clothed with lanceolate striate dusky scales. Stems subsolitary, 

 1-2 ft., slender. Leaves as long as -5 f stem, erect, very narrow, tip obtuse, hairy 

 or glabrate. Umbel nearly simple, sometimes depauperated with 'few spikelets. 

 Spikelets f by f in. 



Var. luclens; style-branches 3 or 4. Khasia; alt. 6-7000 ft., C. . Clarke.
