but the stigmas are long and yellow. The species is named for 

 Prof. Whitney, the distinguished head of the State Geological Survey, 

 in the prosecution of which it was discovered. 



BOLANDRA, nov. gen. Saxifragearum. 



Calyx campanulatus, dilatatus, ultra ovarium liberum longe produc- 

 tus, 5-fidus, lobis triangulari-lanceolatis acuminatis recurvis sestivatione 

 valvatis. Petala 5, fauci calycis inserta, subulato-attenuata, recurva, 

 persistentia. Stamina 5, petalis alterna, iisdem breviora : antherae 

 cordato-biloba?. Ovarium ovatum, basi lata sessile, inferne biloculare 

 multiovulatum, superne longe bifidum, cornubus a3qualibus intus mox 

 apertis stigmate truncato terminatis. Styli proprii vix ulli. — Herba

Bolandra Californica. — Yosemite Valley, on the Mariposa 

 Trail, among rocks, July, H. N. Bolander. [Also coll. by Dr. Torrey, 

 on foot-hills of the Sierra Nevada.) A span to near a foot high ; the 

 stems weak and slender. Leaves thin ; the radical and lowest cauline 

 round-reuiform, about 5-lobed to near the middle, the broadish lobes 

 somewhat 2 - 3-lobed or crenate-incised, on long petioles which are 

 slightly dilated at the base ; or the lower cauline with a dilated and 

 clasping appendage at the base, resembling a pair of foliaceous adnate 

 stipules : the upper leaves, wanting the petiole, pass from pandu'riform 

 or cordate-clasping into ovate or oblong partly clasping bracts. Calyx- 

 tube 3 lines long, very much broader than the included ovary, greenish, 

 or the attenuate-pointed lobes, like the still more attenuate and longer 

 petals, tinged with purple. Anthers emarginate at the top ; the short 

 cells not confluent. The subulate-conical beaks or summits of the ovary 

 are hollow nearly to the stigma, but ovuliferous only below the junction: 

 above, the ventral suture opens early. — For the last few years no one 

 has done so much as Mr. Bolander for developing the botany of his 

 adopted State, and perhaps no one is likely to do so much hereafter. 

 It is with great pleasure that I find among his own discoveries a mod- 

 est but very interesting plant, inhabitant of the far-famed Yosemite
