Newberrya. ERICACEAE. 463 



1 . Flowers solitary, terminal : anthers opening equally by 2 chinks. 



1. M. uniflora, Linn. Plant white (rarely rose-color), inodorous, a span high, 

 glabrous : calyx represented by 2 to 4 bracts or sepals, the uppermost larger : petals 

 5 and stamens 10 (rarely more) : stigma naked. 



In damp woods : not yet seen in California ; but occurs in Oregon, though perhaps less com- 

 monly than in the Atlantic States ; extends on the one hand into South America, on the other 

 into Japan and to the Himalayas. 



2. Flowers several in a spike or close raceme, ivith more regular sepals, and the 

 petals more saccate at base, the terminal floiver mostly with 5 petals and 10 

 stamens ; the others respectively 4 and 8 (or rarely fewer) : anthers more reni- 

 form ; the cells completely confluent into one, which opens by 2 unequal valves, 

 one broad and spreading, the other remaining erect and contracted: margin 

 of the stigma glandular or hairy. HYPOPITYS. (Hypopitys, Dill.) 



2. M. fimbriata, Gray. Near a foot high, glabrous, except a minute pubes- 

 cence of the spike-like raceme : the obovate-cuneate bracts and the spatulate sepals 

 erosely or laciniately fimbriate : some flowers with only 3 petals and 6 stamens. 

 Proc. Am. Acad. viii. 629. 



In the southern Cascade Mountains, Oregon, E. Hall. It may be expected in Northern 

 California. 



M. HYPOPITYS, Linn. , or some form or near relative of this, the common Pine-sap, extending 

 round the world in the temperate zone, occurs in the northern part of Oregon. It is pubescent 

 or rarely glabrous, and the scales and bracts nearly entire. 



19. PLEURICOSPORA, Gray. 



Calyx of 4 or 5 oblong-lanceolate scale-like sepals, with laciniately fimbriate mar- 

 gins. Corolla of as many nearly similar oblong petals, shorter than the calyx. 

 Stamens 8 or 10, glabrous, included : anthers linear, erect upon the apex of the 

 filiform flattish filament and hardly wider than it, apiculate at the retuse apex ; 

 the cells united throughout, opening lengthwise from the base to the apex. Ovary 

 ovate, tapering into a style of about its own length which bears a depressed-capitate 

 stigma, one-celled, with 4 or 5 bilamellate parietal placentae, which are ovuliferous 

 throughout. Capsule fleshy 1 Seeds obovate, with firm rather polished coat closely 

 fitted to the nucleus. Plants light brown or whitish, with the aspect of Mono- 

 tropa, sect. Hypopitys, but stouter ; the stem crowded or at first imbricated with 

 the scales ; flowers in a close erect spike. Gray, Proc. Am. Acad. vii. 369. 



1. P. fimbriolata, Gray, 1. c. A span or more high, glabrous or nearly so : 

 scales of the stem ovate-lanceolate, the lower with erose edges, the upper and bracts 

 with scarious whitish and fimbriate margins. 



In the Mariposa Grove, Bolander. There are indications of a Mexican species. 



20. NEWBERRYA, Torr. 



Calyx of 2 scale-like sepals, resembling bractlets. Corolla oblong, somewhat 

 urceolate, 4 - 5-lobed, withering-persistent ; the lobes spreading, ovate, hairy inside. 

 Stamens 8 or 10, somewhat included : filaments filiform, above the middle bearded 

 with long hairs : anthers oblong, erect ; the cells opening lengthwise, from top to 

 bottom, into two unequal valves. Ovary ovate : style elongated, hairy above : 

 stigma depressed-capitate, entire, umbilicate and pervious : placentae 4, each 2-parted, 

 the two broad plates covered with ovules on both sides, and their edges meeting or
