A FLORA OP GIBRALTAR AND THE NEIGHBOURHOOD 



115 



I Var. Thomasii (Kunth) has many of the lower panicle branches 

 devoid of spikelets, but runs into type. I. Here and there mixed 

 with type ! III. ii. The prevailing form in the Waterfall 

 Valley ! 



Airopsis cjlobosaDesv. Sandy hills; rather rare? 4-5. Spike- 

 lets small, very globose. III. i. Between Pinar del Eey and 

 Jimena, Porta £ Bigo ! perhaps beyond our limits, iii. Between 

 Algeciras and San Koque, Winkl. 



iAntinoria agrostidea Pari. Sandy turfy fields ; locally abun- 

 dant ; 3-4. A short caespitose perennial, spikelets small and 

 short, one floret sessile, the other stipitate, glumes dark, longer 

 than florets. III. ii. Pastures near El Cobre ! iii. Los Barrios 

 Aviation Ground ! I believe also in i., but no definite record. 



Molineria minuta Pari. Similar places ; rare ? 3-4. Annual, 

 panicle very lax, lower pale many-nerved, keeled, glumes shorter 

 than florets. III. i. Gibraltar, Cabrera, Clem. Doubtless the 

 neighbourhood is meant. Pinar del Eey, Porta d- Bigo I labelled 

 Aira lendigera Lag. var. mutica Boiss. 



Var. hatica Wk., with hairs at base of lower pale aslong as 

 the pale, is the commoner form in the province. III. ii. Near 

 Algeciras, Hack.

 hispanica. 



iA. multiculmis Dum. Similar places; rare; 4-5. Distin- 

 guished from last by its clustered spikelets. III. i. Cork Wood 

 Crags ! form with one-awned spikelets. There are two sheets at 

 Kew from Boissier and Eeuter, one labelled A. capillaris Host., 

 the other A. viuUicuhnis Dum., both "Gibraltar," which belong 

 here. They probably come from San Eoque, not from the 

 Eock. 



A. elegans Gaud. Dry sandy and stony places ; frequent, at 

 least locally ; 4-6. Panicle large and very lax, only one flower 

 awned. III. ii. M. de la Torre ! Plentiful in Waterfall Valley!

 in the province.]

 Perennial, in compact tufts, apical portion of awn gradually 

 enlarged upwards, anthers 3-4 times as long as broad. III. i.
