KANTIA 133 
retuse, sometimes acute, rarely bidentate ; superior and median leaf- 
cells 35-65 и, the chloroplasts mostly close to the vertical walls, 
trigones wanting or indistinct ; gemmae ovoid, of one ог two cells : 
underleaves orbicular to broadly ovate, 1-3 times as broad as the 
stem, distant, approximate, or imbricate, bifid to below the middle 
or merely retuse, the lobes acute or obtuse, entire or rarely with a 
tooth on the outer margin: autoicous (polyoicous? ): androecium 
short and capitate or becoming linear-amentiform and attaining a 
length of т mm. or more, arising from the same axil with the © 
branch or at a distance from it; antheridia solitary, ovoid, about 
1 mm. in greatest diameter, short-stalked : archegonia 4-7: per- 
igynium cylindrical, 1.5-2.5 mm. x .6–.9 mm.: capsule 1.5-2.5 
mm. Х .5 m.; seta 1-2.5 cm. long; spores 12-16 у, very mi- 
nutely punctulate ; elaters 180—350 м X 11—15 и, rather obtuse. 
On moist banks and decaying logs. Соттоп in the Coast 
Range Mountains. Mill Valley, Redwood Сайоп, and Olema, 
Marin Co.; Duncan’s Mills (c. fr.) and Cazadero (с. /r.), Sonoma 
Co.; North Fork of the Little River (640, 660, 696) and Men- 
docino (583), Mendocino Co.; Eureka (903, 1221), Humboldt Сау; 
Collected also by Dr. Bolander at Mendocino and in “ Devil’s 
Cañon, Forest Hill, Sierra Nevada, по. 4620." 
The Californian specimens belong chiefly to what is sometimes 
treated as a variety or species under the name Sprengelu, depart- 
ing from the form ordinarily considered typical in the smaller 
more ovate underleaves, which are deeply bifid, with the lobes 
acute. The underleaves, however, often show such extremes of 
form and size in a single tuft and such gradual transitions between 
these extremes that we are convinced that any attempt to divide 
this group into two species according to the character of the 
underleaves is both unnatural and inconvenient. While the Cali- 
fornian specimens represent, in our opinion, but a single species, 
the determination of what name this species shall bear is attended 
with some little difficulty owing principally to the various Ways 
in which Kantia trichomanis has been interpreted and defined by 
European authors. Lindberg * has made the relation of the 
antheridia to the archegonia a ground for distinguishing Kantia 
calypogeia (Raddi) Lindb. from Kantia trichomanis, describing the 
ormer as autoicous and the latter as paroicous, and Kaalaas + has
