1905] OBSERVATIONS ON THE FLORA OF JAPAN. 109 



lobes oval, subtruncate or rounded at the apex, somewhat reflexed, 

 about 4 mm. long, 3-3| mm. wide, main nerves often 3, with loose vein- 

 lets ; tube exserted above the calyx, narrowly cylindrical, scarcely compressed 

 from front and and rear above, somewhat gradually enlarged above, white 

 towards the base, with reflexed and adpressed delicate hairs externally, 

 minutely glandular-hairy above and thinly pilose on the dorsal side and 

 also densely pilose in a ring above the base internally, about 10-12 mm. 

 long, about 2\ mm. across in the broadest portion. Stamens 4, unequal 

 with somewhat shorter posterior ones, inserted to the throat, erect, slightly 

 lower than or equal to the posterior lip in height, filament subulate-filiform, 

 purpurascent, papilloso-pubescent below, softly villoso-pubescent towards the 

 edges with white crispate hairs ; anthers approximate ; cells much divaricate 

 vertically, ellipsoid, glabrous, pale but after bursting yellowish-nigrescent, 

 about 1 mm. long, with white pollen. Ovary glabrous ; lobes erect, close, 

 oval, slightly compressed, pale-viridescent, purple and glandular in the sub- 

 truncato-rounded top, about §-§ mm. long ; gynophore (disk) not large, 

 slightly shorter than the ovary, with an erect adpressed ovato-deltoid obtuse 

 anterior lobe ; style equal to stamens in height, filiform, glabrous, purpura- 

 scent, but pale and somewhat curved towards the stigma, about 14 mm. 

 long including the stigma ; stigma bifid, branches equal, erect-patent, 

 subulate, acute, about 1 mm. long. Nutlets about 3 mm. long, included 

 within the persistent calyx, erect, obovate, sub-trigonous, often slightly com- 

 pressed, subtruncato-rounded at the top with obtuse edges, smooth, black ; 

 gynophore shorter than nutlets, about 11 mm. long. 



Nom. Jap. Maneki-gusa, Yama-lcisewata (Somoku-Dzusetsu, ed. 2, XL 

 no. 49). 



Hab. Prov. Mikawa : Mt. Ishimaki (G. Nagural Sept. 30, 1896, 

 Aug. 1897, Oct. 3, 1898), Kaifuku, cult, from Mt. Ishimaki (G. Nagural 

 Sept. 15, 1898); Prov. Ise {H. Nakanishi !) ; Prov. Kodzuke: Osawa-mura 

 in Tano-gori (T. Aral ! June 15, 1901) ; Prov. Musashi : Tokyo, cult, 

 from Kodzuke (T. MakinoX June and August, 1905). 



Very closely allied to the Chinese Loxocalyx urticifolms Hemsl. (in 

 Joum. Linn. Soc. XXVI. p. 309, tab. 5.), from which it differs by the 

 pubescent habit, shorter leaves, and fewer flowers. 



Lamium humile Maxim. (Ajuga humilis Miq.) may be probably 

 referred to this genus, {Loxocalyx, as L. humilis.)
