THE THISTLE FA^^LV. 325 



C. major, greater tickseed. growing: to at most about three feet high, is a 

 graceful inhabitant of open, sandy woodlands, whtre its pretty Jlowcr-hcads 

 raise themselves on very slender peduncles. Its sessile leaves, divided to 

 the base into three lanceolate, entire segments, produce somewhat the same 

 effect as though they were verticillate. 



C. verticillata, whorled tickseed, found mostly through open pine-woods. 

 is known by its peculiarity of having sessile leaves, twice or thrice dissected 

 into thread-like, entire segments, and which occur at intervals in masses on 

 the stem and thus produce a fine, light effect. The numerous Howcr-hcads 

 have usually from six to ten spatulate-oblong rays. 



C. gladiata, on the contrary, is sparing in its foliage, the stems being 

 naked above and its alternate leaves below quite distinct and slender. They 

 are spatulate-oblong, tapering into long petioles, entire and fleshy. Hut the 

 plant's beauty lies in its large, bright flower-heads with their decp-purplc 

 disks. Through Florida and North Carolina, especially in low pine-barrens, 

 it makes its home. 



C 7indata, tickseed, a rare find indeed, occurs mostly along the coast 

 from Florida to Georgia, where its ray flowers gleam through the shallow 

 ponds of pine-barrens as early as April. They show themselves in their often 

 solitary heads to be rose-purple, and their rays — from eight to nine — are 

 broadly oblanceolate and thrice-toothed at their apices. Of the alternate 

 and linear leaves, those about the base are often nearly a foot long. The 

 plant grows erectly, is smooth and slender, with branches forked towards 

 their summits. 



.With Coreopsis rosea, the pink tickseed, which also grows in open swamps 

 along the coast, it is the only one with other than yellow or particoloured 

 rays. 



C. tinctbria {Plate CLXXIV.), garden tickseed, we see sometimes as 

 an escape, and its similarity to some of the wild species may serve to recall 

 to the mind their personality.
