Scutellaria versicolor minor A. Gray, Syn. Fl. N. Am. 2: Pt. 1, 
378. 1878.* In part, not of Chapm.} nor S. wnor L. 
A small plant. with usually solitary stems from a slender creep- 
ing rootstock. Stems 5-12 cm. long, erect or ascending, rather 
acutely 4-angled, pubescent with short, mostly retrorse or recurved 
white hairs, the pubescence towards the summit glandular, denser 
and more spreading; petioles slender, pubescent with retrorse ap- 
pressed hairs, those of lowest leaves 1.5—3 cm. long, spreading or 
recurved, those of uppermost foliage leaves 1 cm. long or less, as- 
cending ; largest (often the uppermost) leaf-blades 3-6 (usually 5) 
cm. long, 2-3 cm. wide ; smallest (usually the lowest) considerably 
reduced; all broadly ovate, obtuse, cordate with a rather open 
sinus, coarsely crenate, rather sparsely ciliate with short spread- 
ing hairs, pubescent with short appressed hairs on both surfaces, 
but especially along the veins beneath, thin, bright green above, 
paler beneath, conspicuously veiny, the veins prominently reticu- 
lated and almost rugose beneath; inflorescence a simple solitary 
terminal raceme (less often a much-reduced, simple panicle) 2-4 
cm. long, mostly 10-20-flowered; pedicels 2-3 mm. long, rather 
stout, glandular-pilose, ascending ; bracts barely equalling the pedi- 
cels, ovate, obtusish, glandular-pubescent; calyx (in flower) about 
3 mm. long, rather densely pubescent ; (in fruit) about 5 mm. long, 
sparingly pubescent, light green; corolla about 15 mm. long, pale 
blue and white, puberulent; anthers minutely ciliate; nutlets 1 
mm. in greatest diameter, globose, strongly depressed. 
Growing with Circaea alpina L. just below the summit of Bluff 
Mountain, where it was collected August 28 (no. 873). S. venosa 
is closely related to S. cordifolia Muhl. (S. versicolor Nutt.) from 
which it differs in its smaller size, much shorter pubescence of 
leaves and inflorescence, much reduced bracts and considerably 
smaller calyx and corolla. S. cordifolia is mainly a campestrian 
species preferring much lower elevations, and is not known to occur 
anywhere in the region where S. venosa was collected. S. saxatilis 
puosior Benth. may be the same plant, but is not identifiable with 
any certainty from Bentham’s meagre description. It may very 
well be only a form of S. saxatilis. 
MELAMPYRUM LATIFOLIUM Muhl. Cat. 57. 1813. 
Both this species and MZ. dineare Lam. occur near Wolf Creek, 
*S. rugosa Wood,Class Book, Ed. 2, cited here by Gray as a synonym of S.ver- 
stcolor minor, is unquestionably a form of S. saxatilis Riddell, to which Wood him- | 
self referred it in subsequent editions of the Class Book, | :
