13. PRUNELLA L. Sp. Pl. 600. 1753. 
Perennial simple or sometimes branched herbs, with petioled leaves, and rather small 
clustered purple or white flowers, in terminal and sometimes also axillary, dense bracted 
spikes or heads. Calyx oblong, reticulate-veined, about 10-nerved, deeply 2-lipped, closed in 
fruit; upper lip nearly truncate, or with 3 short teeth; lower lip 2-cleft, its teeth lanceolate. 
Corolla-tube inflated, slightly narrowed at the mouth, its limb strongly 2-lipped; upper lip 
entire, arched; lower lip spreading, 3-lobed. Stamens 4, didynamous, ascending under the 
upper lip of the corolla, the lower pair the longer; filaments of the longer stamens 2-toothed 
at the summit, one of the teeth bearing the anther, the other sterile; anthers 2-celled, the 
sacs divergent or divaricate. Ovary deeply 4-parted. Nutlets ovoid, smooth. [Origin of 
name doubtful; often spelled Brunella, the pre-Linnaean form.] 
About 5 species, of wide geographic distribution. Only the following typical one occurs in 
North America. 
_1. Prunella vulgaris L. Self-heal. Heal-all. Dragon-head. Fig. 3598. 
y- y Prunella vulgaris L. Sp. Pl. 600. 1753. 
Pubescent or nearly glabrous; stem slen- 
der, procumbent or ascending or erect, 
usually simple, but sometimes considerably 
branched, 22° high. Leaves ovate, oblong 
or oblong-lanceolate, obtuse or subacute at 
the apex, usually narrowed at the base, 
entire, crenate, dentate, or incised, 1’-4’ 
long, the lowest commonly shorter and 
sometimes subcordate; spikes terminal, ses- 
sile or short-peduncled, very dense, $’-1’ 
long in flower, becoming 2’-4’ long in 
fruit; bracts broadly ovate-orbicular, cus- 
pidate, more or less ciliate; corolla violet, 
purple, or sometimes white, 4-6” long, 
about twice as long as the purplish or green 
calyx; calyx-teeth often ciliate. 
In fields, woods and waste places throughout 
nearly the whole of North America. Native 
and naturalized from Europe. Native also of 
Asia. Thimble-flower. All-heal. Brown-wort. 
Carpenter’s-herb or -weed. Hook-heal or 
-weed. Heart-of-the-earth. Sicklewort. Blue- 
curls. May-Oct. 
Prunella laciniata L., differing by pin- 
natifid or deeply incised leaves, found near .- 
Washington, D. C., and illustrated in our first
