Very variable; stems or branches 6 in. to 3 ft., sometimes as thick as a swan 8 
quill, spreading and branching, sometimes rooting, and glabrous or densely pubescent 
or villous. Leaves 1-6 in. long, very variable in breadth, narrowed into the often 
very long petiole, rarely lobed or cut. Spikes 1-8 in., whorls continuous or interrupte , 
lower bracts leaf-like. Calyx short, teeth always obtuse. Corolla azure, tube ier 
as long as the calyx, usually glabrous, limb small; upper lip erect, 2-lobed ; lobes M 
lower subequal or midlobe broadest. Nutlets ths; in. long, deeply rugosely pitte the 
A very common species in the hilly countries of N. India, being the largest of e 
genus ; in the low grounds forming a bushy herb sometimes 3 feet high, with wide y 
spreading decumbent branches and abundant spikes of blue flowers. In the higher 
elevations it assumes a lower and more slender form with smaller leaves (A. sikkim- 
ensis, Miq.), with the corolla laxly hairy and its tube scarcely exserted. This for 
has sometimes stems only a few inches high and irregularly toothed leaves. Whethe 
A. macrosperma, and any of its states, be the A. decumbens, Thunb., of Japan, 8$ 
would follow from Don's and Bentham’s references, is unknown to me, as I have seen 
no Japanese Ajuga with a geniculate corolla-tube. According to Maximoviez's descrip” 
tion of A. decumbens, it must differ in the deeper sharper calyx-lobes, the more 
_ prominent midlobe of the corolla, and in the minutely reticulate nutlets. 
eV ee VAR. Thomsoni; glabrous, stems slender flaccid rooting prostrate, spikes with a 
very slender rachis, calyx-teeth very short rounded, corolla glabrous, tube exsertec.

certainly only an upland state of A. macrosperma. However unlike the extreme 
low-land form, it is united by intermediates collected near to it at lower 
elevations. 
Var. breviflora; smaller, branches more slender than the type 4 in.-2 ft., 
corolla-tube shorter sometimes quite included often hairy. A. decumbens, Don

Prolus. Fl. Jap. 46; Mazim. l. c. 822.— Higher parts of the Khasia Mta» 
ascending to 10,000 ft. in Sikkim. Bebar; top of Parusnath, J. D. H.—Perhap 
all the Himalayan forms of A. macrosperma should be referred to this, but I can fin 
no definite characters for them. 
UNKNOWN SPECIES.

or fruit.

ebracteate or crowded in a terminal thyrse. Calyx erect, 10-nery E
