Additions to the flora of peninsular Florida 

 I. NATIVE SPECIES 



John K. Small 



The species enumerated below are for the most part additions 

 to the hitherto known flora of the United States. They are all 

 new to the mainland and only five of them were heretofore known 

 as members of the flora of the United States from specimens 

 collected on the Florida Keys. 



With one or two exceptions, these additions were brought to 

 notice by exploration carried on by the New York Botanical 

 Garden, and the type specimens of the species here described for 

 the first time are preserved in its herbarium. 



Thysanella robusta sp. now 



Plants mainly 6-9 dm. tall, often somewhat spreading, much 

 stouter than those of T. fimbriata: leaves 3-6 cm. long, ascend- 

 ing; blades linear, acute, striate-nerved ; ocreae imbricate on the 

 lower part of the stem, mostly separated above, copiously fringed: 

 racemes mainly 4-7 cm. long, 8-10 mm. thick, the ocrealae 

 closely imbricate, each terminating in an elongate pale tip: calyx 

 white, often becoming pink; the outer sepals entire or irregularly 

 cleft, the inner ones becoming 3.5 mm. long: filaments about 4 

 mm. long: achenes fully 2 mm. long and fully 1.5 mm. wide, 

 long-beaked. 



A species hitherto confused with Thysanella fimbriata. It 

 differs from that species by its much greater size, the larger sepals 

 and achenes. Specimens collected at Braidentown, Florida, 

 August 28, 1901 {Tracy 7638), may constitute the type. 



Other recently collected specimens belonging to this species are: 

 Jensen, March 25, 1897, Curtiss 5837. Dade County, November 

 & December, 1903, Eaton 776. 



Warea Carteri sp. nov. 



Annual, glabrous, bright green: stems erect, 4-15 dm. tall, 

 simple or widely branched above, mostly purple-tinged below, 

 terete: leaves alternate; blades linear or sometimes cuneate,
