474 BORAGINAGEAE 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 3-celled by the 

 nieeting of the dilated placentae in the ^xis. Capsule small, 

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

 spl'ittiiig 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.

 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 tometitum, 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: cdrolla 6 lines long, tubular-funnelform, sparsely hairy: capsule 

 gloiipse-oVate, pointed ; 2 lines long. On dry open hillsides, southern 

 Oreigon to California, 



Order LXV. BORAGINACEAE Lindl. Nat. Syst. ed. 3, 274. 

 Mostly scabrous or hispid-hairy plants with bland watery 

 juide, 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 regular and 

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

 g;ynous 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 carpels. Ovules ana- 

 tropous 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 radicle. 



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. 



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

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



Tribe ii Herbs or soinetrmes shrubby plants. Style terminal, 

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

 margirt of a disk, often surmounted by a mostly conical appen- 

 dage. 

 2 Heliotropium Corolla^lobes imbricated in the bud with the sinuses 



plaited : fruit splitting into 4 one-seeded or 3 two-celled and two-seeded 



carpels.
