11. PYCNaNTHEMUM, Michx. MOUNTAIN MINT. BASIL.

Calyx ovate-oblong or tubular, about 13-nerved, equally 5-toothed, or the three upper teeth more or less united, naked in the throat. Corolla short, more or less 2-lipped; the upper lip straight, nearly flat, entire or slightly notched; the lower 3-cleft, its lobes all ovate and obtuse. Stamens 4, distant, the lower pair rather longer; anther-cells parallel.--Perennial upright herbs, with a pungent mint-like flavor, corymbosely branched above, the floral leaves often whitened; the many-flowered whorls dense, crowded with bracts, and usually forming terminal heads or close cymes. Corolla whitish or purplish, the lips mostly dotted with purple. Fl. summer and early autumn.--Varies, like the Mints, with the stamens exserted or included in different flowers.

(Name composed of p?????, _dense_, and ???e??, _a blossom_, from the dense inflorescence.)

[*] _Bracts and equal calyx-teeth awn-tipped, rigid, naked, as long as the corolla; flowers in rather dense mostly terminal heads; leaves rigid, slightly petioled._

1. P. aristatum, Michx. Minutely h.o.a.ry-p.u.b.erulent (1--2 high); leaves ovate-oblong and oblong-lanceolate, acute, sparingly denticulate-serrate (1--2' long), roundish at the base.--Pine barrens, N. J. to Fla. and La.

Var. hyssopiflium, Gray. Leaves narrowly oblong or broadly linear, nearly entire and obtuse.--Va. to Fla.

[*][*] _Bracts and equal and similar calyx-teeth not awned._

[+] _Leaves linear or lanceolate, nearly sessile, entire, very numerous; capitate glomerules small and numerous, densely cymose, imbricated with many short appressed rigid bracts._

2. P. lanceolatum, Pursh. _Smoothish or minutely p.u.b.escent_ (2 high); _leaves lanceolate or lance-linear_, obtuse at base; _heads downy_; bracts ovate or lanceolate; _calyx-teeth short and triangular_.--Dry thickets, Ma.s.s. to Dak., south to Ga. and Ark.

3. P. liniflium, Pursh. _Smoother and leaves narrower_ and heads less downy than in the last; the narrower _bracts and lance-awl-shaped calyx-teeth pungently pointed_.--Dry ground, Ma.s.s. to Minn., south to Fla. and Tex.

[+][+] _Leaves lanceolate to ovate, sessile or nearly so, denticulate or entire; heads larger and fewer, with fewer and looser bracts._

4. P. mutic.u.m, Pers. _Minutely h.o.a.ry_ throughout, or becoming almost smooth, corymbosely much branched (1--2 high); _leaves ovate or broadly ovate-lanceolate_, varying to lanceolate, _rather rigid, acute, rounded or slightly heart-shaped at base_, mostly sessile and minutely sharp-toothed, prominently veined, green when old; _the floral ones_, short bracts, and triangular or ovate calyx-teeth, _h.o.a.ry with a fine close down_; flower-cl.u.s.ters very dense.--Maine to S.
