NEW PLANTS FROM NORTHERN CALIFORNIA. 



We seem to be very slow in attaining to anything like a 

 thorough knowledge of the botany of the northern portions of 

 our State. Since the days of Bolander's and Kellogg's collect- 

 ing in the counties of Mendocino and Humboldt — and those days 

 were more than twenty years ago — very few, if any notes or 

 specimens have come in from that particular district. Mr. Rattan 

 has made one or more vacation excursions in that direction, with 

 instructive results, but that is all. Mr. Carl C. Marshall, a 

 zealous and enterprising amateur, a resident of Humboldt County, 

 gained the summit of the Trinity Mountains in July last, and 

 brought back with him specimens enough to indicate that this 

 new district which he has been first to set foot upon, botanically, 

 merits a thorough and careful exploration. His collection, 

 although only a small one and the species represented by very 

 scant specimens, contains among other probably new species the 

 following two Saxifragaceous plants. 



RiBES Marshallii. Glabrous, branches with stout but rather^ 

 short triple spines; leaves roundish, 5-lobed, the lobes incised; 

 peduncles i -flowered; flower pendulous, an inch in length; calyx- 

 segments elongated oblong, spreading or recurved, dark red- 

 purple; petals 2-3 lines long, spatulate oblong, salmon color, 

 filaments slender, more than a half inch long; anthers very small 

 for the size of the flower (^ Hne long), oblong, obtuse at both 

 ends; ovary very bristly. 



Summit of Trinity Mountains, flowering in July near lingering 

 snow-drifts. The species is a gooseberry, intermediate between 

 R. Menziesii and R. Lobbii, with remarkably large and hand- 

 some flowers. The character and quality of the fruit is of course 

 unknown 



MiTELLA DivERSiFOLiA. Leavcs all radical, ovate to orbicu- 

 lar, with 3-5 somewhat irregular, shallow but angular lobes, the 

 margin otherwise entire and somewhat ciliolate, the base cordate 

 with nearly closed sinus; scape a foot high, spike indistinctly 

 unilateral ; calyx-lobes white and petaloid ; petals white, cuneate- 

 oblanceolate, palmately trifid at the abruptly widened apex; 

 Stamens 5.
