slightly purplish, mostly erect, narrow, 1 5-20 mm. long ; bracts 

 subequal, striate-ncrvcd, hyaline margined, attenuate, mucronulate- 

 acute or aculeolate, or the apex of the inner one apiculate from a 

 narrowly scarious-obtuse or even bifid tip, the outer one clasping 

 for 2-5 mm. at base ; interior scales about equaling the bracts or 

 slightly exserted ; flowers 5-1 1, on slender exscrted pedicels, pale 

 blue, perianth delicate, about 10 mm. long: capsules j^ale green 

 or purplish tinged, trigonous-subglobose or obovoid, abruptly con- 

 tracted above and below, 3-4 mm. high, on pedicels 20-25 nim. 

 long, exserted and slightly diverging for about quarter of their 

 length : seeds not fully mature. 



. Based chiefly on Nash's no. 13, " Plants of Central Peninsular 

 Florida"; collected "near Lake Dot, Eustis, on dry sandy hillside, 

 March 12, 1894." In flower and fruit. 



The same plant was collected by Prof Underwood, also at 

 Eustis, in 1891, and further specimens have been examined as fol- 

 lows :. Hibernia, March, 1869, W. N. Canby ; Pine Barrens near 

 Jacksonville, March 17, 1804, A. H. Curtiss. 



Sisyrinchium Nashii 



Nearly related to 5. Floridaiium, but much smaller and 

 slenderer, and flowering in June and July instead of March. 



Very slender and delicate, growing in thin wisps of a {cw stems 

 and leaves sheathed with a dense fibrillose coating around the base, 

 leaves few, erect, about half the height of the stem, .5-2 mm. wide, 

 rather less closely and strongly striate than in S. Flondcvium and 

 frequently denticulate, especially towards the scarcely terete apex : 

 stems k\N, erect, 20-30 cm. high, mostly i mm. or less wide, the 

 very narrow margins often, or usually, minutely denticulate ; leaves, 

 stems and peduncles sometimes obscurely roughened with minute 

 points on the sides : bracteal leaf almost setaceously slender, much 

 shorter than the peduncles; peduncles 1-3, almost filiform, often 

 not perceptibly margined, more or less unequal, mostly 4-6 cm. 

 long : spathes narrow, 13-15 mm. long, the bracts mostly thinner 

 and less sharp-pointed than in 5. Floridamun, the inner one fre- 

 quently surpassing the outer and scarious-obtuse at the apex ; 

 flowers smaller than in 5. Floridamun : capsules pale, 2-3 mm. high, 

 subglobose or often broader than long on slenderly exserted sub- 

 spreading pedicels 17-22 mm. long: seeds subglobose, black, 

 finely rugulose-pitted. with a large umbilicus.
