 oak and black and white oak ridges. 



I recommend this plant for rock gardens.

7326. LYCOPUS [Tourn.] L. Bugleweed 



Leaves all more or less serrate, not even the lowest incised; tops of nutlets scarcely 

 oblique, more or less tuberculate, at least the outer margin with one or more 

 tubercles (not very conspicuous in Lycopus asper). 

 Calyx lobe's lanceolate or deltoid, blunt, shorter than the mature nutlets, rarely 

 equaling them. 

 Root of year old plants ending in a subterranean tuber, usually simple; roots of 

 older plants not ending in a tuber, stoloniferous and usually many of the 

 stolons bearing tubers; older plants much and widely branched, usually 20-50 

 cm high except sometimes taller when growing in a crowded environment; 

 leaves usually sessile, sometimes on petioles up to 7 mm long, the widest ones 

 ranging from 8-25 mm in width, the greatest number of teeth to a side gen- 

 erally 5-7; nutlets usually 1-1.5 mm long 1. L. uniflorus. 



Root of year old plants not ending in a subterranean tuber; older plants strongly 

 stoloniferous, rarely with subterranean tubers; older plants usually simple or 

 sparingly branched, 30-90 cm high; leaves usually petiolate (some plants 

 with all the leaves sessile), petioles up to 20 mm long, widest leaves ranging 

 from 18-55 mm in width, the greatest number of teeth to a side 7-14; nutlets 



usually 1.6-2 mm long 2. L. virginicus. 



Calyx lobes narrow, very acute to acuminate, longer than the mature nutlets. 

 Leaves sessile. 



Stems glandular-puberulent, most of the internodes more than 2 cm long; leaves 

 ovate to lanceolate, the margins coarsely and irregularly serrate, generally 

 with 3-5 teeth to the side; outer bracts minute, filiform, much shorter than 



the calyx 3. L. sessilifolius. 



Stems pubescent with flat, multicellular hairs, most or all of the internodes less 

 than 2 cm long; leaves oblong-lanceolate, the margins regularly and sharply 

 serrate, generally with 6-8 teeth to a side; outer bracts conspicuous, usually 

 as long as or longer than the calyx. (See excluded species no. 545, p. 1087) 



L. asper. 



Leaves petiolate 4. L. rubellus. 



Leaves (at least the lowest) generally more or less incised or pinnatifid; nutlets mostly 

 1-1.5 mm long, top very oblique, not tuberculate but the outer margin raised and 

 entire (rarely slightly undulate), the inner angle not raised. 



Stems glabrous or with a few short and long hairs 5. L. americanus. 



Stems more or less densely pubescent with long, spreading, multicellular hairs. . . . 

 5a. L. americamis var. Longii. 



1. Lycopus uniflorus Michx. Map 1781. All of my specimens except 

 one are from the lake area. The Parke County specimen was found east 

 of Rosedale, in "Nigger Legs" prairie, which is now drained. It is fre- 

 quent throughout the lake area and usually common where found. It grows 

 mostly on the borders of lakes in the moist, sandy or marly shores. I have 

 seen this species common in the litter on the shore of a lake, while in a 

 zone back of the litter, Lycopus virginicus was found ; but the two species 

 were restricted to two separate zones. It is also found in marshes, sphag-
