Menyanthes. TOLEMONIACE^. 485 



5. MENYANTHES, Toum. I ',r. 'Kit KAN. 



Calyx 0-parted. Corolla nearly eampaimlato, the lobes valvate in tho bud with 

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

 Style slender, persistent : stigma L'-lohed. Capsule globular, rather fleshy, inclined 

 to burst, irregularly. Seeds not, very numerous, hut, 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 rootstoek, bearing alternate: leaves, with long petioles shcat.hing at base, and 3 

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

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

 the filaments arc long exsorted. 



In shallow water or wet ground, near San Francisco (Hitfelow), and Sierra Valley (Mrs. Pulnifer 

 Ames) ; extending round tin; world in tin' northern portion of the, temperate zone. 



Oum.i: LOGANIACE^J. There is a Buddleia in Coulter's Californian Collection, No. 625, 

 winch we do not possess. As none has l>een detected since, it is more jtrolMible that Coulter's 

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



ORDER LXIII. POLEMONIACE^J. 



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 pi-til, whirh has a .'{-celled ovary and a 3-lobed style; 

 the fruit a loculieidal .'5 - many-seeded capsule, with placenta in tho axis. Calyx 

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

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

 introrse, opening lengthwise. Stigmas occupying tho inner sido of tho narrow or 

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

 triangular axis, which bears the seeds: these 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 suffrutescent 

 or more woody stems. In Gilia, 6, the cells of tho ovary and tho stigmas are 

 occasionally reduced to two. -Cray, I'roc. Am. Acad. viii. 247. 



Mainly an American ;md especially a North American and Mexican order, of few genera, but 

 111:111 y species, increasing in number westward, most abundantly represented in California ; of no 

 marked sensible qualities or economical uses, excepting ornamental cultivation. 



'ni!.v:.\ s< AMiKNH, Cav., of Mexico, a well-known cultivated clim>)cr, is an outlying member of 

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

 ovary. 



* Corolla quite regular : seeds wingless. 



1. Phlox. Stamens unequally inserted and included within the narrow tube of the salver- 



shaped corolla. Seed-coat unchanged in water. Leaves opposite, entire. 



2. Collomia. Stamens unequally inserted in or below the throat of tho funnelfortn or salver- 



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

 we). Leaves all or mostly alternate, sometimes divided. 



3. Oilia. Stamens equally inserted on the throat or tube of the corolla : filaments not declined. 



Seeds almost, always mucilaginous when wet. Leaves various. 



4. Polemonium. Filaments more or less declined, otherwise nearly as Oilia. Leaves all 



pinnate and alternate, and corolla short. 



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



f>. Lceselia. Stamens more or less exserted. I'pper sinuses of tho corolla more deeply cleft 

 than the others.
