Abundant on the open ground behind Fort San Antonio, 

 in the low ground near Tangle Eock, and at Morro branco. 

 This is a large plant, forming thick tussocks in low-lying country ; 

 the leaves are numerous and long and narrow, the inflorescences 

 few and rather compact, the racemes long and slender, the 

 rhachis hardly flattened. The flowers numerous and white. It 

 belougs to the same section as P. virgatum, but even in habit is 

 distinct, the leaves and inflorescence being much narrower.

Herba rigida erecta, vix csespitosa. Folia pauca erecta 

 late linearia, culmo multo breviora, acuminata striata scabrida, 

 6 uncias longa, ^ unciam lata. Ore et marginibus vagina) albo 

 lanatis. Ligula laciniata, laciniis rotundatis membranaceis. 

 Culmus sesquipedalis ad inflorescentiam vaginis tectus. Panicula 

 erecto-nutans 6-uncialis, racemis 10. Ehachis sinuata scabra vix 

 complanata. Flores per paria in pedicellis brevibus pubescentibus 

 quam in prsecedente pauUo majores. Gluma externa late ovata 

 obtusa carinata cymbiformis .... plana eUiptica obtusa ; gluma 

 interna indurata ovata obtusa cymbiformis minute striata. 

 Palea elliptica obtusa striata. Antherse flavae. Styli atro- 

 purpurei. 



On the altered phonolite of Morro branco, growing in clefts 

 of the rock and on the slopes. 



This species is allied closely to the preceding, but is dis- 

 tinguished at first sight by its habit ; it does not form the large 

 long-leaved tussocks of that species, but grows in small tufts with 

 a few erect, stift' leaves, much shorter and broader than those of 

 the other. The whole plant, too, is smaller and more condensed.
