NEW OR LITTLE KNOWN SPECIES OF TRILLIUM. II 



Trillium decumbens n. sp. 



Stem decumbent, mostly solitary but sometimes clustered, 

 5-i2 cm tall, densely pubescent above the middle : leaves broadly 

 ovate or suborbicular, 4-5-9 cm long, obtuse or sometimes acutish 

 at the apex, mottled and somewhat pubescent at the base on the 

 veins beneath, sessile : flowers sessile : sepals about half as long 

 as the petals, lanceolate to broadly lanceolate, acute, green tinged 

 with purple: petals 3. 5— 7 cm long, 5~i2 mm broad, acuminate or 

 sometimes acute, erect, twisted, brownish-purple : stamens about 

 one-fourth as long as the fully grown petals : filaments very short, 

 from one-half to three-fourths as long as the prolongation of the 

 very broad connective : stigmas short, stout and recurved : berry 

 ovoid, about i cm in diameter, prominently and sharply angled. 



In rocky woods of the Sand Mountain region in northeastern 

 Alabama. Blooms on the ridge near Collinsville, DeKalb county 

 (type locality), the latter part of April. 



Trillium decumbens was first discovered by Mr. C. L. Boynton of the Bilt- 

 more Herbarium, in the spring of 1901. The decumbent habit and erect, twisted 

 petals immediately attracted Mr. Boynton 's attention, and I copy from his notes 

 concerning this species as follows: "Stem very short and invariably declined. 

 Leaves resting upon the ground, thus presenting a most unique appearance. The 

 petals are more than twice as long as the acute sepals." 



A number of plants which blossomed in the greenhouse and which were col- 

 lected at the original station, were observed and measured by the writer. Plants 

 with stems only half a decimeter long were invariably decumbent. This habit, 

 together with the large, erect, twisted petals and very prominent prolongation of 

 the connective, afford characters which readily separate this species from all 

 other pubescent species in this group. — T. G. Harbison.
