BOSCHNIAKIA 
Brown or reddish, glabrous, parasitic on Ericaceae. Leaves densely crowded. 
Flowers sessile or short-pedicelled, many, in a dense scaly-bracted terminal cone-like spike. 
Calyx short, cup-like, shorter at the back, with 3 teeth in front. Corolla swollen at base 
on | side; upper lip entire; lower lip 3-lobed or-toothed. Stamens about equaling the 
corolla; anther-sacs blunt at base. (Honor of some Russian, a Mr. Boschniak. ) 
A. Calyx with 2 hair-like bracteoles at base; calyx-teeth subulate; corolla-lips nearly 
equal; placentae 4. W._ B. strobilacea Gray 
AA. Calyx without bracteoles; calyx-teeth triangular, blunt; lower corolla-lip 1% as 
long as the upper; placentae 2. W. 
B. hookeri Walp. 
OROBANCHE BROOM-RAPE 
Glandular-pubescent, white or yellowish or reddish or violet. Leaves scattered. 
Flowers in spikes or racemes. Calyx in ours unequally 5-toothed. Corolla strongly 
2-lipped; upper lip emarginate or 2-lobed; lower lip 3-lobed. Stamens included; anther- 
sacs usually mucronate at base. Style usually persistent until opening of capsule. -(Gk. 
orobos—=a vetch, agchone=a strangler; thought injurious to vetches.) 
A.  Calyx-lobes plainly longer than the tube. 
B. Pedicels 5—16 mm. long; stem simple or branched. 
C. Stem 5—10 cm. high; anthers woolly. (Mvyzorrhiza corymbosa.) W. E. 
0. comosa Hook. 
CC. Stem 20—30 cm. high; anthers glabrous or slightly hairy. E. 
0. californica C. & S. 
BB.  Pedicels O—3 mm. long; stem simple. E. 
0. ludoviciana Nutt. 
AA. Calyx-lobes equaling or shorter than the tubes; stem branched above; flower nearly 
sessile. E. 0. pinorum Gey. 
PINGUICULACEAE (Lentibulariaceae) Bladder-wort Family 
Herbs, in water or on damp soil. Leaves either basal and tufted and entire, or else 
dissected or scale-like and on elongated stems. Flowers solitary on scapes, or else racemose 
on leafless axes of inflorescence, perfect; pedicels bracteolate. Calyx 2—5-parted. Co- 
rolla spurred at base, 2-lipped; upper lip usually erect, concave on the sides, plicate, entire 
or 2-lobed; lower lip larger, spreading or reflexed, 3-lobed, with a palate. Stamens 2. 
Ovary superior, ovoid or globose, |-celled; style short or none; stigma 2-lobed. Fruit 
a capsule. Seeds many. 
A. Terrestrial plants; leaves entire; flowers purple-violet. PINGUICULA (p. 362) 
AA. Aquatic or marsh plants; leaves dissected or apparently none; flowers yellow. 
UTRICULARIA (p. 361) 
UTRICULARIA BLADDER-WORT 
Free-floating or mud-anchoring. Leaves finely-divided in nearly all, sometimes ap- 
parently none, bladder-bearing in most water-species, with a few mud-covered bladders 
or none in mud-species. Flowers yellow (ours), elevated above the water, racemose, or 
solitary on slender scapes or scape-like stems, pedicels 2-bracteolate. Calyx deeply 2-lobed. 
Upper lip of corolla usually entire; throat usually bearded. 
A. Leaf-segments terete, their margins entire.
