NOTES ON TRILLIUM 325 



The T. uanthum and T. tinctorium of Rafinesque (Bot. U.S. ii. 

 98) may belong here. 



2. A. form represented by Catesby's plant, having oblanceolate 

 petals with long narrow bases standing erect in the centre of the 

 flower, and conspicuously longer than the lanceolate to broadly 

 linear-lanceolate sepals ; stamens about one-third the length of the 

 petals, connective scarcely prolonged above the anther. Good 

 specimens of this form occur in Herb. Banks, labelled ''Am. 

 Sept."; the leaves are slightly larger and more elongated (elliptic- 

 oval to ovate, 7-8 by 3-3-5'7 cm.), the petals slightly broader 

 (6-8 mm. in breadth), while the anthers vary from 10-18 mm. in 

 length, the connective ending almost on a level with the pollen - 

 sacs ; the stigmas vary from 4*5 to 5 mm. long, and are straight or 

 slightly recurved at the tip only. The leaves are conspicuously 

 mottled. Curtis's Bot. Mag. tab. 40, " taken from a plant 

 which flowered in my garden last spring from roots sent me the 

 preceding autumn, by Mr. Eobert Squibb, Gardener, of Charleston, 

 South-Carolina," is a good representation of the specimens. 



A similar specimen occurs in a volume of plants collected by 

 Mr. Job Lord in Carolina (Herb. Sloane, 285, f. 4); Lord's label 

 reads : " This Plant Grows in moist fertil ground y* has a deep & 

 loose (or light) soil. It has three Leaves at y^ top of y^ stalk, 

 amidst w'' stands upright one dark reddish purple Flow'', w" it is 

 full ; but greenish before it is full blown. You may see y® flow'' in 

 it's perfection in one of y^ samples, & y*" shape & mann^' of standing

 y^ Leaves y* now (dried) look most green, w" they are fresh look of 

 y^ colour of y^ Liver of a beast, before it be sodden, as it is when 

 taken out of y® beast." The leaves are ovate, not exceeding 6*5 cm. 

 in length by 4*5 in breadth. The petals which closely resemble 

 those of Catesby's plant are 4 cm. long (sepals 2*5 cm.), and the 

 stamens 1-2 cm. The connective is not prolonged beyond the 

 pollen-sacs. The specimen of Trillmm sessile in Walter's Carolina 

 herbarium is also similar. In his Flor. Carol. 126 (1788), Walter 

 has T. sessile " flore sessili erecto, petalis coriaceis purpureis." 



Nearly allied to the Carolina form are some specimens from 

 Florida {''Trillium sessile L.?" in herb. Chapman) which seem to 

 approach most nearly to the idea of Dr. Small's 2\ Undencoodii. 

 The somewhat robust stems reach 24 cm. in length and -5 in 

 thickness ; the leaves are those of Catesby's figure, ovate to ovate- 

 lanceolate and more or less elongated to an acute or subacute tip, 

 mottled and prominently 3-nerved ; they reach 12*5 cm. in length 

 by 5*3 cm. in breadth. The lanceolate petals i4'5-5'5 cm. by 

 1-2-1-4 cm.) exceed the sepals (3*3-4 cm. long), and are 3|- to 4 

 times as long as the stamens ; the connective is prolonged beyond 

 the anther, and the stigmas are short (3-3-5 mm.). 



A similar but somewhat smaller specimen from Arkansas occurs 

 in herb. Nuttall. 



Another similar and generally robust form with a stout hori- 

 zontal rhizome, and a stem from 16 to 40 cm. long and as much as 

 6-7 mm. thick a little above the base, has broadly ovate to ovate-
