174 THE TRUE GRASSES. 



causes eruptions, trembling, and confusion of sight in 

 man and in flesh-eating animals, and very strongly in 

 rabbits, but it does not affect swine, horned cattle, or 

 ducks. Arthrochortus Lowe belongs to this genus. 



274. (272) Kralikia Cosson & Durieu. Spikes slender ; 

 spikelets very small ; empty glumes two ; callus of the 

 flowering glumes bearded. 



Species one {K. Africana C. & D.), in Algiers. 



275. Kerinozoma Steud. A much-branched prostrate 

 grass with only 3-5 spikelets in each spike, with a small 

 cup-shaped, membranaceous, bracteate leaf enclosing the 

 base. Terminal spikelet none. Upper leaf-sheath in- 

 flated, its blade short. 



Species one {K. littoralis Zolling.), in Java. 



276. (273) Oropetium Trim A dwarf grass, the minute 

 spikelets almost immersed in the notches of the flexuose 

 rachis. Flowering glumes awnless. 



Species one (0. Thomceum Trim), in the East Indies. 



277. (194) Jouvea Fournier. Only the ? plant known. 

 First empty glume cartilaginous, and, like the second, 

 grown fast to the rachis for half its length. 



Species one (J. straminea Fourn.), on the sea-coasts of 

 Mexico. A rush-like, thorny grass. 



278. (270) Monerma Beauv. Spikes cylindrical, subu- 

 late, articulated. Spikelets deeply immersed in the rachis, 

 awnless, terminal with two, others with one empty glume, 

 these coriaceous ; flowering glumes membranaceous. 



Species three, one (M. subulota Rom. et Schult.) in the 

 mediterranean regions, South Africa, and Australia ; one 

 from the Pacific Islands and Australia to Ceylon ; the 

 third in Madagascar. 



278a. Ischnurus Balf. fil. Like 3fonerma, but the joints 

 of the rachilla are provided in front with wing-like ap- 

 pendages which almost cover the deeply-immersed empty 

 glumes. Spikelets not filling up the excavations in the 

 rachis ; the spike is therefore pitted. 



Species one (I. pulchellus Balf. fil), a native of Socotra 

 (an island east of Tropical Africa).
