250 Rhodora [DECEMBER 
In the northern plant, which usually occurs'in coniferous woods, 
the slender peduncles are mostly appressed-pubescent, and the 
transition is more gradual than in Cynmoglosum virginicum from the 
lower long-petioled to the upper amplexicaul leaves. The calyx in 
anthesis is 2-2.5 mm. long; the corolla 6-8 mm. broad, with ovate- 
oblong lobes and open sinuses; and the compressed pyriform-obovoid 
nutlets are 4-5 mm. long. This northern plant is of broad range in 
Canada and the Northern States, while the southern Cynoglossum 
virginicum is only doubtfully reported from southern New England. 
That the two are distinct species seems clear from the characters 
above enumerated, and the northern plant may be distinguished as 
CyNoGLossuM boreale, sp. n. Planta 4-8 dm. alta; caule basi 
villoso-hispido, pedunculis elongatis (usque ad 1-2 dm. longis) 
appresso-pubescentibus; foliis radicalibus ellipticis vel lanceolato- 
ovalibus 1-3 dm. longis hispidis lamina petiolo fere aequanti, caulinis 
in petiolum brevem attenuatis vel subamplexicaulibus, superioribus 
oblongis 7-16 cm. longis basi auriculis rotundatis amplexicaulibus ; 
racemis geminis 4—8-floris deinde r-2 dm. longis; pedicellis fructi- 
feris patente recurvis infimis 1.5-3 cm. longis; calycibus appresso- 
pubescentibus 2—2.5 mm. longis, lobis ovato-lanceolatis; corollis 6-8 
mm. latis, lobis ovato-oblongis; nuculis tumidis ovoideo-pyriformibus 
glochidiato-echinatis 4-5 mm. longis. —QueEBEC, beneath Larix
