BORAGINACEAE. Borage Family. 



Herbs, usually rough with coarse hairs. Leaves simple, commonly entire and 

 alternate. Flowers complete, in one-sided spikes or racemes, coiled spirally 

 (scorpioid) and uncoiling as flowering proceeds. Calyx with commonly 5 

 divisions or teeth. Corolla regular, 5-lobed, with 5 stamens inserted on its 

 tube and alternating with its divisions. Ovary superior, deeply 4-lobed (except 

 in Heliotropium), with a simple style inserted between the lobes, in fruit split- 

 ting into 4 one-seeded nutlets. Style entire (in ours) or none. Nutlets com- 

 monly roughened or prickly, inserted on a short thick prolongation of the re- 

 ceptacle, here sometimes referred to as the gynoba.se. Endosperm none, except 

 in Heliotropium. 



A. Style none. 

 Ovary not lobed, in fruit splitting into 4 one-seeded closed cells; anthers connivent; 



glabrous glaucous succulent perennial 1. Heliotropium. 



B. Style present. 

 Ovary deeply 4dobed, when ripe splitting into 4 one-seeded nutlets. 

 Nutlets erect; ours annuals. 

 Corolla white. 



Calyx persistent ; lowest ieaves opposite 2. Allocarya. 



Calyx and short pedicel at length deciduous; leaves alternate 3. Cryptanthe. 



Calyx persistent or circumscissile near the base; leaves mostly in a radical rosette, 



the cauline alternate 4. Plagiobothrys. 



Corolla yellow 5. Amsinckia. 



Nutlets flattish, divergent, margined all around or at apex with bristles; corolla minute, 



white; small annuals 6. Pectocarya. 



Nutlets broad, depressed, covered all over with short barbed prickles; corolla blue with 

 a ring of appendages or crests at the throat; perennials 7. Cynoglossum. 



1. HELIOTROPIUM L. Heliotrope. 



Ours a prostrate fleshy perennial with white flowers in dense one-sided spikes. 

 Corolla salverform, short, with open throat; sinuses more or less plaited in the 

 bud. Anthers connivent, nearly sessile. Style none in ours. Stigma annular 

 and turned downward over the summit of the ovary and thus resembling a 

 skull-cap. Ovary not lobed but separating when ripe into 4 one-seeded closed 

 cells. (Greek helios, sun, and trope, a turning, ''the flowers beginning tc 

 appear at the summer solstice.") 



1. H. curassavicum L. Chinese Puslev. Glabrous, glaucous, the stems 

 branching, % to several ft. long; leaves obovate to broadly oblanceolate; spikes 

 mostly in pairs; corolla white with the yellow eye changing to purple. 



Common along the seashore, in stream beds, and in low moist or alkaline 

 lands throughout California. June-Xov. Immigrating locally.
