16. E. ovata, Nees. — Recorded in Mueller's Census from North Australia. 

 The variety pallida of this species was collected at Lake Eyre by Andrews, and 

 at Charlotte Waters by Giles. 



17. E. nervosa, Ewart and Cookson. (Plate III.) 



A stiff grass, erect stems about 2 ft. high, arising from a woolly horizontal 

 rhizome. Glabrous in all parts except spikelets. Leaves narrow, subulate. 



Panicle dense from 4|- to 5^ inches long. Spikelets pedicellate, lateral 

 spikelets on short pedicels, terminal spikelet on a pedicel about as long as the 

 glwmes. Outer glumes persistent, firm, acute, 14 to 19-nerved, deeply concave, 

 with sUghtly scarious edges. Outer and inner glumes of approximately equal 

 length, being 3 to 4 lines long. Flowering glumes longer than outer glumes, 

 densely hairy to about the middle, tapering to a short awn-hke point. Palea 

 slightly shorter than flowering glume, minutely bifid with a few hairs on back. 

 Two large lodicules are situated at the base of the ovary. 



The nearest affinit}' is to Eriachne ovata var. pallida, but Eriachne nervosa 

 is a much larger plant, and the outer glumes are more rigid and have 14-19 

 nerves.

 {Gapriola, Adans., 11 Q3 ; Dactilon, Vill., ll^T! ; Fibichia, Koel, 1802). 



Flowering glume pubescent. Palea with 2 prominent distant nerves. — 

 3. C. tenellus. 



Flowering glume ciUate with long hairs on the keel and margins. Palea 

 very narrow, the two nerves closely contiguous, forming a ciliate keel. — 2. C. 

 convergens. 



Flowering glume with a horizontal ring of long spreading hairs below the 

 point. Palea rather broad, with two distant nerves, and a ring of hairs like 

 the flowering glume. — 1. C. ciliaris. 



1. C. ciliaris, Benth. — Charlotte Waters, Giles.
