Sedum (Seda genuina) hakonense Makino sp. nor. 



Perennial, about 6-10 cm. in height, glabrous*. Stems loosely tufted, 

 erect or ascending, decumbent and radicant at the base, narrowly terete. 

 Leaves sparse, not dense, spreading or erect-patent, linear, more or less 

 narrowed towards the sessile base, rounded-obtuse at the apex, entire, 

 carnose-fLat, green (or more or less glaucous ?), £-2| cm. long, 2-3 mm. broad. 

 Cyme 2-4 cm. across, 3-fid with patent branches, which are often again 

 divaricately dichotomous ; bracts similar to leaves in form, the largest one 

 2 J cm. in length in our specimens. Flowers laxly disposed, sessile, about 

 7 mm. in diameter. Calyx 4-partite with broad and rounded sinuses ; lobes 

 minute, short, erect-patent, unequal in size, deltoid but the largest one 

 often oblong, rounded- obtuse at the apex, fleshy, punctate, i-l* mm. loug. 

 Petals 4, white ? but ferruginous when dried, patulous, ovate-lanceolate, 

 acute, entire, thickly membranaceous, delicatedly 3-nerved, the lateral nerves 

 dividing from the lower portion of the midvein and disappearing before 

 reaching the apex. Stamens 8, equal to petals in height, alternipetalous 

 ones adherent to the basal sides of petals, oppositipetalous ones inserted 

 to inframedia of petals ; filaments filiform ; anther ovate-elliptical, 

 purple ? Hypogynous scales 4, minute, cuneato-obovate, retuse-truncate or 

 obcordate^at the apex. Ovaries 4, erect, equal to petals in height, connate 

 with the lower half, tapering up towards the style ; style short, erect,
