 glauca, supra punctato-scabra, subtus glaberrima, radicalia longe- 

 petiolata, obovata, late obovatave, obtusa, plus minus mucronata,

 limbo dimidio 5-lobo, lobis rotundato-quadrantibus. Stamina 

 anthero 2 mm. longo, filamentis aequanti. Stylus inclusus, 8 mm. 

 longus, staminibus superans. Nuculas 5 mm. longae, 3 mm. latae.

Planta nostra in littore maritimo regionis subarcticse Asije 

 orientalis copiose crescit a planta typica europsea statura valde 

 robustiore, floribus fructibusque majoribus, sty lis calyce duplo 

 staminibusque superantibus, pedicellis fructiferis nutantibus di- 

 versa est. 



2. Mertensia rivularis DC. var. nova japonica Takeda. 

 Caulis erectus usque ad 4 dm. altus, glaber, supremo hirtellus, 

 ramosus. Folia basilaria plus minus longe petiolata (plerumque 

 10-20 cm.), late cordato-ovata, acuta acuminatave, 4-8 cm. longa, 

 3-7 cm. lata, subtus fere glaberrima, supra adpresse pilosula, 

 margine adpresse ciliata, plus minus glauca, caulina inferiora 

 breviter petiolata, superiora sessilia, ovata, acuminata, basi sub- 

 cordato-rotundata, subtus fere glabra, supra hirtella. Flores 

 longe pedicellati, pedicellis florendi tempore calyce duplo, demum 

 4-plo longioribus, hirsutis, eb];acteatis. Calyx 5-partitus, lobis 

 lineari-lanceolatis, acutiusculis, trinervis, extus glabris, intus mar- 

 gineque pilosis, 4^-6 mm. longis, post anthesin elongatis 7-8 mm. 

 longis. Corolla magna, 15 mm. longa, tubo albo calyce sesqui- 

 longiore, Hmbum cseruleum subiequanti. Stylus filiformis, corolla 

 aequilongus, nee exsertus.
