The basal part of the O-shaped outgrowth now begins to grow 

 upward, in which it is accompanied at the same rate by the upper 

 portion of the O, which at the same time carries forward the 

 apical growth of the leaf. The cavity, of the pitcher thus grows 

 in depth by the upward growth of the tissue by which it is sur- 

 rounded. The bottom of the cavity is subsequently elevated by 

 the further growth of the tissue beneath it." 



Plants of 6". ptLVpurea kept under glass for a year at the New 

 York Botanical Garden showed a marked tendency to form 

 blade-like structures instead of ascidial leaves. Goebel (/. c. 73) 

 describes in several species this tendency to produce leaves with- 

 out pitchers at the close of the vegetative period. 



The peculiar form of the leaves of Sarracenia has attracted the 

 attention of the curious ever since their discovery. A specimen 

 of vS. flava brought to France by a sailor with the legend that it 

 grew on a fragrant Canadian tree was named leaf of the incense 

 tree {TJmris Livipidi foliiait) and figured by de L'Obel (Adversaria 

 430- 1570)- S. purpurea was figured and described by Clusius 

 (Hist. Rar. PI. 4 : 82. 1601 ) as a plant whose leaves were like the 

 flowers of Aristolochia. He named it Linionmm peregrimini from 

 its fancied resemblance to sea-lavender {Livioniuni caroliniamtni). 

 John Josselyn in " New England's Rarities," 1672, describes it 

 as follows : [John Josselyn, New Eng. Rar. (ed. Tuckerman) — 

 (95). 1865] Hollow Leaved Lavender is a Plant that grows in 

 salt Marshes overgrown with Moss, with one straight stalk about 

 the bigness of an Oat straw, better than a Cubit high, upon the 

 top standeth one fantastical Flower, the Leaves grow close from 

 the roots, in shape like a Tankard, hollow, tough, and always 

 full of Water ; the root is made up of many strings, growing only 

 in the Moss, and not in the P^arth, the whole Plant comes to per- 

 fection in August when it has Leaves, Stalks, and Flowers as red 

 as blood, except the Flower which hath some yellow admixt." 



The Indians of southern Minnesota called it ko-ko-moccasin, or 

 owl's moccasin. P'rom the rhizome and young leaves a concoc- 

 tion was made by the Canadian Lidians which they believed to be 

 a remedy for small-pox (Millspaugh, Am. Med. PI. 19-3. 1887). 

 This has been used to a certain extent in homeopathic pharmacy.
