measurements should be made when the flower is fully developed, as the ap- 

 pended table will prove. Ten different plants of Trillium ludovicianum were 

 measured daily by the writer, for ten days after the first opening of the flow- 

 ers. From the data given it will be seen that at one stage of development the 

 stamens were half as long as the petals, but less than one-third on the sixth 

 day after anthesis and but slightly more than one-fourth as long on the ninth 

 ' day, when the petals had reached their highest development.

Trillium vaseyi n. sp. 



Stem erect from a horizontal rootstock, 2.5~5 dm tall, smooth: 

 leaves sessile or subsessile, broadly round-rhomboidal, abruptly 

 acuminate, contracted into a broadly-winged, sessile or subses- 

 sile base, i-2 dm long : flowers on a deflexed or recurved pe- 

 duncle, 1-2 times the length of the flower: sepals lanceolate to 

 ovate-lanceolate, acute, 2-4 cm long : petals ovate or broadly 

 ovate, of about the same length and twice as broad as the se- 

 pals, acute or obtuse, dark purple : stamens about twice as long 

 as the ovary at anthesis, spreading : filaments about as long as 

 the anthers, purple : stigmas short and slender, less than half 

 as long as the anthers, spreading or recurved : berry ovoid, 

 somewhat angled, pale purple or reddish, i-2 cm in diameter. 



Moist, shady woods of the high mountains of the southern 

 Alleghanies. Ascends to 1,500 meters in Macon county, N. C. 

 April and May. 



Trillium vaseyi has been, I presume, confounded with extreme forms of 

 T. erectum L , 1 c. It may be readily separated from it, however, by its long 

 slender filaments, smaller stigmas and peduncle, which is deflexed beneath the 

 leaves before anthesis. This Trillium was collected in the mountains of North 

 Carolina in 1878 by Dr. George Vasey, whose name I take pleasure in asso- 

 ciating with this species. — T. G. Harbison.
