70 BUCKWHEAT FAMILY 



Thysanella. Wild Buckwheat. Knotweed (Genus 



Thysanella) 



Although the individual flowers of the buckwheat family 

 are usually small, yet where many are crowded together 

 and bloom in hundreds of racemes, as in these plants, they 

 make a very attractive display. Low and bushy in growth, 

 with many stems, Thysanella fimhiriata is especially abun- 

 dant on the hills of Polk County, in the interior of the 

 peninsula. Where blue lupines blossom in winter and 

 spring, this thysanella, ranging in color from palest shell- 

 pink or white to rose, is beautiful in late summer and 

 autumn, but, unlike the lupine, it blooms more or less 

 throughout the year, and in the rocky soil near Miami, 

 as well as on the hills of the interior of the peninsula, 

 its flowers may be found at any season. 



The stouter T, robusta usually blooms in white, but 

 its flowers are sometimes tinged with pink. It is easily 

 distinguished from the preceding species as its outer 

 sepals are entire, or nearly so. 



Thysanella fimbriata. Flowers 5-parted, small, pink or 

 white, many, in many slender racemes 1-3 in. long. Outer 

 sepals fringed. Stamens 8. Plants 1-2 ft. tall, much 

 branched. Leaves alternate, narrow, 1-2 in. long. Ocreae 

 fringed with bristles. Dry soil. Blooming chiefly in sum- 

 mer and fall. Fla. and Ga. 



Thysanella robusta. Snowdrift. Similar to above species, 

 but stouter, 1-3 ft. tall. Flowers usually white, outer sepals 

 not fringed. Pinelands. Blooming all the year. Fla. 

 peninsula. 



Dog-Tongue. Wild Buckwheat. Umbrella Plant 



(Genus Eriogonum) 



Like the thysanellas, this stouter wild buckwheat also 

 blossoms at any time of the year, but, unlike it, the flowers 

 are in small clusters, instead of in racemes, and are dotted
