348 EUBIACE^. 



orbicular or roiiud-obovate, never stipulate, several of the uppermost 

 pairs connate: 11. numerous, in several interrupted spikes; corolla ^^ in. 

 long, yellow, glabroiis. — Common on dry bushy hills of the inner Coast 

 Ranges, and in similar places among the Sierras northward. May, June. 



8. C. subspicatuiii, Greene. H. & A. Bot. Beech. 349 (1841), and 

 Torr. Bot. Mex. Bound, t. 23, under Lonicera. L. hispidala, var. sub- 

 spicata, Gray. Size of the last, bushy but more straggling, the many 

 ultimate branches and branchlets short and all floriferous; almost all 

 the plant, except the upper face of the leaves, densely glandular-pubes- 

 cent: leaves small, coriaceous, narrowly oblong, obtuse, tapering to a 

 distinct petiole, very veiny on both faces, deep green above, apparently 

 white-tomentose between the veins beneath, none of them either stipu- 

 late or connate: spikes numerous, almost panicled, but the whorls of 

 flowers few, each whorl with a pair of bracts at base: corolla ^o in. long, 

 yellowish. — In the Coast Ranges, but southward only. How this and 

 the preceding can have passed for varieties of C hispiduluin passes our 

 comprehension. Probably no country can exhibit three species of this 

 group which are more pronouncedly distinct.

 L. Gerard, Flora Gallo-Provincialis, 224 (1761): Jussieu, Gen. 196 (1789). 



Our species herbs (Cephalanthus and some species of Galium shrubby) 

 with opposite or verticillate mostly exstipulate entire leaves, and 

 4-merous perfect (rarely dioecious) flowers. Calyx-limb obsolete, or of 4 

 teeth. Stamens distinct, alternate with the corolla-lobes and inserted on 

 its throat or tube. Ovary 2— 4-celled, with a solitary ovule in each cell. 

 Fruit indehiscent, dry or baccate. 



1. CEPHALANTHUS, Lmnxus (Button-bush). Shrubs with oppo- 

 site or ternate leaves, and flowers in dense globose terminal and axillary 

 peduncled heads. Calyx inverse-pyramidal, 4-toothed. Corolla with 

 long slender tube and small 4-cleft limb. Stamens 4, short, on the 

 throat of the corolla. Style slender, long-exserted; stigma capitate; 

 ovary 2-celled. Fruit achene-like, 1 — 2-seeded. 



1. C. occideiitalis, Linn. Sp. PI. i. 95 (1753). Shrub or small tree, 

 with ovate-lanceolate leaves 3 — 5 in. long, rather glossy above, often 

 more or less pubescent: fl. white, in heads 1 in. thick, these solitary or few 

 or several toward the ends of the branches. — River banks of the interior, 

 especially of the Sacramento from Shasta Co. to Solano; also on the 

 lower San Joaquin. June — Aug.
