474 BORAGINACE^E ERIODICTYON 



ticulated leaves and violet purple or white flowers in scorpioid 

 cymes. Sepals narrow, not enlarging upward. Corolla funnel- 

 form or approaching campanulate. Filaments more or less in- 

 cluded, inserted on the tube and more or less adnate to it, usually 

 sparsely hirsute. Ovary nearly or completely 2-celled by the 

 meeting of the dilated placentae in the axis. Capsule small, 

 crustaceous, 4-valved, that is first loculicidal then septicidal thus 

 splitting into 4 half-carpels which are closed on one side owing to 

 the widely dilated placentae, and partly open on the other. Seeds 

 rather few, pendulous, 



E. glutinosum Benth. 1. c. Glabrous, and glutinous with a balsamic 

 resin: stems erect, 3-5 feet high: leaves lanceolate, 3-6 inches long, irregu- 

 larly more or less serrate, sometimes entire, whitened beneath between the 

 reticulation by a minute and close tomentum, dark green and glabrous above, 

 persistent for more than a year : flowers purple, numerous, in elongated naked 

 thyrsoid cymes: sepals subulate, 2 lines long, sparsely hirsute: corolla 6 lines 

 long, tubular-funnelform, sparsely hairy: capsule globose-ovate, pointed; 2 

 lines ong. On dry open hillsides, southern Oregon to California. 



ORDER LXV. BORAGINACE^ Lindl. Nat. Syst. ed. 2, 274. 



Mostly scabrous or hispid-hairy plants with bland watery 

 juice, mostly alternate entire leaves without stipules and rather 

 small regular flowers in scorpioid racemes spikes or cymes. 

 Flowers perfect, generally 5-merous. Calyx free from the 

 ovary, usually persistent. Corolla gamopetalous, mostly regu- 

 lar and 5-lobed, sometimes crested or appendaged in the throat. 

 Hypogynous disk usually present but inconspicuous. Stamens 

 inserted on the throat or tube of the corolla, as many as and 

 alternate with its lobes. Style simple, rising between the 

 divisions of a deeply 4-parted ovary, or from the summit of an 

 undivided one. Ovary of 2 biovuled entire or more commonly 

 deeply 2-lobed carpels, making it appear like 4 1-ovuled car- 

 pels. Ovules anatropous or amphitropous. Fruit 4, or by 

 abortion fewer, nutlets, or a drupe containing 2-4 nutlets or 

 cells, rarely reduced to one. Seeds with little or no albumen, 

 and straight or curved embryo with superior or centripetal 

 radical. 



I Ovary undivided and surmounted by the style. 

 TRIBE i Low herbs shrubs or trees. Style once forked: the 

 branches tipped with a simple stigma. 



Coldenia Corolla-lobes imbricated or partly convolute in the bud: style 

 simply and deeply 2- cleft: fruit separating into 4 dry carpels. 



TRIBE n Herbs or sometimes shrubby plants. Style terminal, 

 sometimes very short or none, entire. Stigma a fleshy ring, or 

 margin of a disk, often surmounted by a mostly conical appendage. 



2 Heliotr opinm Corolla-lobes imbricated in the bud with the sinuses plait- 

 ei: fruit splitting into 4 one-seeded or 2 two-celled and 2-seeded carpels.
