Mmyantlies. POLEAlONIACEiE. 485 



5. MENYANTHES, Toura. Buckbeak. 



Calyx 5-parted. Corolla nearly eampanulate, the lobes valvate in the bud with 

 the margins turned inward, the upper surface densely white-bearded, deciduous. 

 .Style slender, persistent : stigma 2-lobed. Capsule globular, rather fleshy, inclined 

 to burst irregularly. Seeds not very numerous, but large in proportion : the seed- 

 coat hard, smooth and shining. — A single genuine species, flowering in spring. 



1. M. trifoliata, Linn. Low and smooth perennial, with long and stout creep- 

 ing rootstock, bearing alternate leaves, with long petioles sheathing at base, and 3 

 oblong leaflets : scape naked, elongated, terminated by a short raceme of white or 

 pinkish flowers : anthers dark brown, sagittate : in some flowers the style, in others 

 the filaments are long-exserted. 



In shallow water or wet ground, near San Francisco (Bigelow), and Sierra Valley (.l/re. Pnhih r 

 Ames) • extending round the world in the northern portion of the temperate zone. 



Order LOGANIACE.a3. There is a Buddleia in Coulter's Californian Collection, No. 625, 

 which we do not possess. As none has heen detected since, it is more probable that Coulter's 

 specimen was gathered on the route to California, as far south and east at least as Arizona. 



Order LXIII. POLEMONIACE^. 



Chiefly herbs, with bland and colorless juice, simple or divided leaves, and no 

 stipules; readily distinguished from related orders by having all the parts of the 

 regular flower live, except the pistil, which has a 3-celled ovary and a 3-lobed style; 

 the fruit a loculicidal 3 - many-seeded capsule, with placenta in the axis. Calyx 

 imbricated in the bud, persistent. Corolla convolute in the bud, not plaited, rarely 

 a little irregular. Stamens on the corolla alternate with its lobes, distinct : anthers 

 introrse, opening lengthwise. Stigmas occupying the inner side of the narrow or 

 .filiform lobes of the style. Valves of the capsule usually separating from a thickish 

 triangular axis, which bears tin- seeds: th.'se amphitropous or nearly anatropous, 

 small, with a thin or soft coat, commonly developing mucilage when wetted. Em 

 bryo rather large, straight, in the axis of fleshy albumen. — A few have suffrutescenl 

 or more woody stems. In Gi/ia, § G, the cells of the ovary and the stigmas are 

 occasionally reduced to two. — Gray, Proc. Am. Acad, viii, 247. 



Mainly on American and especially a North American and Mexican order, of few genera, bnt 



many species, increasing in number westward, most abundantly n presented in California ; of no 



marked sensible qualities or economical uses, excepting ornamental cultivation. 

 i -i.i i i i rm us, < 'av., of Mexico, a well-known cultivated climb r, is an outlying member of 



this order, its pinnate leaves tendril-bearing, and a large fleshy disk encircling the base of the 



ovaiy. 



» Corolla quite regular : seeds wingless. 



1. Phlox, stum. us unequally inserted and included within the narrow tube of tho salvcr- 

 sbaped corolla. Seed-coat unchanged in water. Leavi a opposite, i 



•J. Collomia. Stamens unequally inaorted in or below tin tl roat of tho runnelform or salver- 

 shaped corolla: filaments slender, often exserted. Seeds copiously mucilaginous when 

 wet Leaves all or mostly alternate, sometimes divided. 



:s. Gilia. Stamens equally inserted on the throat or tube of the corolla : filaments not declined. 

 Seeds almost always mucilaginous when wet. Leaves various. 



I. Polemouium. Filaments moi less declined. Otherwise nearly as Gilia. Leaves all 



p innate and alternate, and corolla short. 



* » Corolla with limb somewhat irregularly cleft : seeds wing-margined. 



5. Lceselia. Stamens more .>i less exserted. Uppei ol the corolla more deephj cleft 



than the others.
