HEATH FAMILY 



65 



white-hairy within, slightly so or subglabrous outside, deeply 4-lobed in the lateral 

 flowers, mostly 5 or 6-lobed ou the terminal ones, withering-persistent. Stamens 

 6 to 12, mostly 8 or 10; filaments long-hairy at and above the middle; anther-cells 2, 

 opening lengthwise. Ovary ovoid, 1-eelled, hairy; placentae 4 to 10, sometimes 

 with a placenta 2-lamellate; style short, long-hairy, the hairs appearing as a sort 

 of collar beneath the yellow stigma; stigma strongly anmilar-umbilicate. — Spe- 

 cies 1 or 2, Pacific North America. (Dr. J. S. Newberry, botanist of one of the 

 Pacific Railroad surveys in 1855, and author of a memoir on the forest trees of 

 northern California and Oregon.) 



1. N. congesta Torr. (Pig. 316.) Gnome Plant. Stem 1 to 4 inches high, 

 very thick; corolla 4 to 7 lines long, the linear or oblanceolate sepals as long or 

 longer ; stigma conspicuous, forming a yellow 

 eye to the flower. 



Forest humus, 500 to 2500 feet : Redwood 

 belt from Monterey Co. to Humboldt Co. Also 

 in Nevada Co. North to Washington. June. 



Flower note. — Segregation of this species into sev- 

 eral is dependent upon structural features of the 

 flower, which is, however, found to be more and more 

 variable, as to its various parts, with each new gather- 

 ing of this seldom-collected plant. The type of Hemi- 

 tomes pumilum Greene agrees perfectly with the fig- 

 ures of Newberrya congesta (Hemitomes eongestum 

 Gray) in the Pacific Railroad Report (6^:80, pi. 12), 

 except in the cross section of the ovary. The ovary of 

 Hemitomes pumilum shows 8 or 9 cord-like or round- 

 ish placentae, but towards the upper part of the ovary 

 these placentae often become 2-lamellate. Since the 

 structure of the placentae varies from top to bottom 

 of the ovary-cell in our material, it is to be suspected 

 that ample material of typical Newberrya congesta 

 might show similar differences.

22. PLEURICOSPORA Gray 



Whitish or light brown saprophytic herb with imbricated scales. Stems simple, 

 arising in clusters from a thick ball of fibres and terminating in a dense spike. 

 Flower parts all glabrous. Sepals 4 or 5 (or 6), distinct, scale-like, the margins 

 remotely fimbriate. Petals 4 or 5 (or to 8), distinct. Stamens 8 or 10; filaments 

 linear-filiform, glabrous. Ovary ovate, 1-celled, the 4 to 8 parietal placentae large, 

 or 1 or 2 of them small. Style columnar; stigma umbilicate-capitate. Fruit a wat- 

 ery berry. — Species 1. (Greek pleuricos, at the side, and spora, seed, the placentae
