POLEMONIACEJ5. 



the lobe* a line long, scarcely spreading; anthers after dehiscence 

 somewhat hairy . 



Summits of the Coast Range peaks and ridges: Gabilan Mountains, 

 Brewer; Mt. Hamilton, Greene; Mt. Diablo, Kelloyy; Mt. Tamalpais, 

 Miss Eastwood; Vaca Mountains, Jepson, parasitic on Adenostoma 

 faseiculatum, the dark red or dark brown thyrsoid-congested inflo- 

 rescences 2 in. thick or more, looking at first glance not unlike small 

 burnt stumps where fire has passed through the Chamisal; Snow Mt., 

 Lake Co.. Brandegee. May. 



2. BOSCHNI AKIA C. A. Mey. 

 Stems thick, simple, arising from rather large globose tubers which 

 are-developed at the point of attachment of the parasite to the root of 

 the host plant. Flowers without bractlets, sessile or pedicellate, more 

 or less concealed by scaly subtending bracts, the whole forming a 

 dense spike. Calyx; short, cup-shaped, truncate behind and with 

 teeth in front, or entirely truncate. Corolla ventricose; upper lip 

 erect or fornicate, entire or bifid; lower 3-parted. Stamens slightly 

 exserted. Stigma bilamellar. the lobes right and left, or 4-lobed. 

 Capsule 4-valved, each valve with 1 placenta. (Bosehniaki. a Russian 

 botanist. ) 



1. B. strobilacea Gray. Tubers 2 to 3 in. in diameter, bearing 

 1 to G spikes; spikes deep red-brown in age; scales much imbricated, 

 very broad and obtuse; calyces truncate or with 1 to 4 teeth anteriorly 

 and laterally disposed; upper lip of corolla entire, emarginate or bifid; 

 filaments densely bearded at base. 



Higher Coast Range ridges (Santa Cruz Mountains, Oakland Hills, 

 Mt. Tamalpais, Mt. St. Helena), northward to British Columbia; 

 commonly parasitic on the roots of Manzanita. May. The oblong- 

 spikes in many cases bear a marked resemblance to Sugar Pine cones; 

 in other cases the inflorescence is more open and the specific name less 

 applicable. Lower flowers rarely with bractlets. For a detailed 

 account of this peculiar parasite see Erythea, v. 03, pi. 1 & 2. 



90. POLEMONIACE/E. Gilta Family. 



Herbs or a few species slightly suftrutescent. Leaves alternate or 

 opposite, entire, lobed or divided. Flowers complete, 5-merous except 

 that the superior ovary is 3-celled, either solitary, in loose clus- 

 ters, capitate, racemose, corymbose or paniculate. Calyx persistent, 

 in one subgenus irregular. Corolla regular, convolute in the bud. 

 Stamens inserted on corolla, alternate with its lobes, often unequal in 

 length. Style 3-cleft. Capsule loculicidally 3-valved. One species 

 of Gilia has a 4-merous corolla and some exceptions as to the capsule 

 are noted under that genus. 



Calyx herbaceous throughout; filaments hairy at base; leaves alternate, 

 pinnate L Polemoxium. 



Calyx more or less scarious below the sinuses, at least not herbaceous 

 throughout.
