Sisyrinchium implicatum 



Growing in close tufts from contracted rootstocks and pro- 

 ducing a dense entangled mass of slender fibrillate roots ; often 

 assurgcnt at base, the numerous weak stems Hexnous-erect or 

 spreading in a loose entanglement, pale dull green, perhaps slightly 

 glauccsccnt. Leaves very slender, weakly erect orflcxuous, .5-T 

 mm. wiile, 5-15 cm. long, narrowly blunt-pointed or acute, finely 

 close-striate, the edges smooth, or serrulate when young : stems 

 equally slender with the leaves narrow-margined, the edges smooth 

 or obscurely denticulate, geniculate near the top at the single node 

 and bearing i or 2 short peduncles with deflected spathes; peduncles 

 almost capillaceous, margined slightly curved or straight, approxi- 

 mate, 2-4 cm. long, surpassing the slender bracteal leaf: spathes 

 \'ery small, the bracts somewhat membranous and finely nerved, 

 equal, "or either one slightly longer than the other; the outer one 

 10-15 "11"- long, contracted-clasping for 3-5 mm. at base, narrowly 

 acute, hyaline-margined below ; inner bract acute or scarious-ob- 

 tiise and apiculate : flowers 3-5, small, on pedicels slightly exserted 

 or scarcely so ; perianth very delicate and faintly nerved, pale blue, 

 apparently about 8 mm. long ; stamineal column about 5 mm. high.

Sisyrinchium rosulatum 



Prostrate or ascciulin^^ in rosulatc tufts, or sometimes nearly 

 erect, pale dull green or glaucescent not turning dark in dryin<:^, 

 the deii.ser tufts from contractedly short-branched wood}' rootstocks, 

 the roots delicate and fibrillate ; tufts sometimes very small, be- 

 coming 25 cm. in diameter: basal leaves short, 2-8 cm. long, 1-2 

 mm. wide, the broadened base membranous and hvalinc-manjincd 

 the weak nerves becoming rather distant, in larger leaves .5 mm. 

 apart : apex of the leaf apiculate acute or sometimes more attcn- 



.uate, the margins denticulate to closely sharp-serrulate or even 

 sub-ciliolate : stems of the smaller tufts very short, only 6-30 

 mm. long, often concealed by the leaves, bearing one or two much 

 longer peduncles : stouter plants may become 20 cm. high, the 

 stems with two remote nodes each supporting an erect leaf and 

 mostly two peduncles, or rarely the lower node developing a 



.slender erect branch : stem slender, subterete, narrowly margined,
