BILTMORE BOTANICAL 



STUDIES 



restris from various sections of the United States, leads me to con- 

 sider L. loo??iisi a valid species, and, in view of its rather obscure 

 publication, I make bold to recharacterize it. 



Perennial, 3-6 dm high : stem usually branched near the sum- 

 mit, striate, minutely roughened with blackish glands, or nearly 

 smooth below : leaves sessile, mostly opposite but occasionally 

 alternate, linear, obtuse at the apex, tapering to a slender base, 

 2-5 cm long, 1-3 mm wide, the uppermost, or bracts of the inflores- 

 cence, abruptly reduced in size, 3-5 mm long and about i mm wide; 

 they are firm in texture, veinless, the midrib and revolute margins 

 prominent beneath, and on both surfaces appear black or brown- 

 ish-black spots, the lower bearing in addition many small brown 

 glands : axils frequently bearing short branches or fascicles of 

 small leaves : racemes narrow, few-flowered, leafy-bracted, termi- 

 nating the main stem and upper branches, the terminal 6-io cm 

 long, those of the branches 2-5 cm in length : pedicels 3-6 mm long, 

 scarcely exceeding the bracts and of about the same length 

 throughout the racemes : sepals oblong or oblong-lanceolate, acute, 

 2-3 mm long, bearing on the edges and sometimes on the outer 

 surface, minute stalked glands : corolla about i cm broad, the lobes 

 oval or ovate, acute, yellow with a few brown lines or spots : sta- 

 mens unequal, the filaments dilated below, united near the base 

 and thickly covered, as is the lower portion of the corolla, with 

 minute, yellow, stalked glands : sinuses of the filaments broad, 

 bearing low, triangular teeth or appendages : capsule spherical. 



Grows in low grounds near streams and was found in flower June 8, 1901. 

 This species finds its nearest relative in L. terrestris 1. c, but presents many 

 points of difference. The most obvious characters are found in the somewhat 

 glandular stem, the narrow, linear, obtuse leaves with brown glands on the under 

 surface, the scarcely tapering, less floriferous racemes with their shorter pedicels 

 and longer bracts, the smaller corollas with broader, more acute segments and 

 the tooth-like lobes in the sinuses of the filaments. — C. L. Boynton.
