lacera , however, not only occurs somewhat sparingly in 
the mountains, but also extends out into the higher hills 
of the Piedmont Plateau in Alabama, Georgia and South 
Carolina, and even into the Coastal Plain of North Caro¬ 
lina. Therefore, besides becoming rarer, the parent spe¬ 
cies become widely scattered as they approach their 
southern limits. 
According to the specimens examined, H.lacera has 
been found in only two counties in the southeastern 
states where at least one of the purple-fringed segregates 
has also been found. These are Mitchell and Transylvania 
Counties in North Carolina. This absence of the parent 
species growing in the same region accounts, perhaps, for 
the rarity of XH.Andrewsii south of New England. 
Description : Roots somewhat fleshy, fusiform, elon¬ 
gated. Plant essentially glabrous throughout, 16-75 cm. 
high. Leaves oblong-obovate, elliptic or lanceolate, 7-20 
cm. long, 2.5-8 cm. wide. Dorsal sepal oblong to ovate- 
elliptic or ovate-orbicular, concave, obtuse, 4-9 mm. long, 
2-5 mm. wide. Lateral sepals asymmetrically ovate, 
ovate-elliptic or ovate-oblong, obtuse to acute, 4-11 mm. 
long, 2-6 mm. wide. Petals essentially linear-oblong 
(oblong-elliptic to narrowly oblong-spatulate), essentially 
entire, commonly with irregularly denticulate-crenulate 
margins, erose, or rarely with obsolescent subhastate- 
fringed lobes at base with entire upper half, 4-11 mm. 
long, 1—4 mm. wide; apex broadly rounded, obtuse- 
truncate, rarely sinuate-retuse. Lip tripartite, 6-17 mm. 
long, 8-22 mm. wide across the lateral lobes; lateral lobes 
narrowly cuneate-flabellate,5-ll mm. long, laciniate half 
way to the base or more (often to the base) with long cap¬ 
illary fringes; median lobe entire and spatulate-clavate 
to deeply-fringed and broadly cuneate or narrowly flabel- 
late, rarely narrowly oblong-spatulate or orbicular with 
coarse, shallowly eroded apex, 4-14 mm. wide. Spur
