Perennial, glabrons, attaining about 57 cm. in height. Stem woody, 

 erect, slender, strict, terete, smooth, atternately provided with fine elevated 

 lines on two sides throughout. Leaves obovato-oblong, or narrowly oblong, 

 rounded-obtuse, shortly attenuated below and suddenly obtuse at the base, 

 narrowly revolute on the margin, sessile, firm in texture, about J-2cm. 

 long, numerously and minutely pellucid-punctate, the midrib and veins 

 (usually 2 or sometimes 3 on each side) prominent beneath, the lower leaves 

 fallen oif in flower. Inflorescence ramose, cymes densely flowered ; bracts 

 small, the upper ones minute and subulato-ovate or subulato-lanceolate. 

 Flowers 1J-1| cm. across, bright yellow ; pedicels much shorter than the 

 flowers. Sepals 5, rhombeo-oval-ovate or rhombeo-oval-elleptical, shortly 

 acuminate, loosely nigro-punctate on the margin, thickish, 2i-3 mm. long 

 in flower. Petals 5, patent, oblong, somewhat oblique, shortly attenuated 

 at the base, obtuse, about 1 cm. long. Stamens numerous, hardly tria- 

 delphous, shorter than the petal, about 7J mm. lon^ ; filament filiform, 

 delicate ; anther minute, rounded. Ovary ovoid -conical, trisulcate, 3 mm. 

 long, 3-locular ; styles 3, slender, longer than the ovary, spreading or

Hah. Prov. Tosa : Ikku-mura {T. MaJdnol Sept. 27, 1892). 



This species has the general habit of Hypericum erectum Thunb., but 

 evidently difl'ers from it by the tapering sepals and pellucid-punctate leaves. 

 It grows in sunny places on hills.
