410 BORAGINACEAE (BORAGE FAMILY) 



Much resembling the preceding, less strongly caespitose, the stems usually 

 taller; pubescence less dense and often merely villous-hirsute : thyrsus rather 

 long and narrow: stamens and style sometimes but little longer than the 

 corolla: seeds 12-22, angled by pressure, rather deeply alveolate. (P. ciliosa 

 Rydb. 1. Co 33: 149.) Colorado to Montana and Washington. 



6. EMMENANTHE Benth. 



Annuals. Corolla yellow or yellowish, campanulate, persistent. Seeds 

 several. Otherwise like Phacelia. 



Corolla equaling or exceeding the calyx-lobes . . . . . . 1. E. scopulina. 



Corolla distinctly shorter than the calyx-lobes . . . . . 2. E. salina. 



1. Emmenanthe scopulina A. Nels. Bull. Torr. Bot. Club 25: 380. 1898. 

 Small, pubescent but scarcely glandular, branched from the base; branches 

 short, ascending, 1-8 cm. long: leaves ovate, elliptic, or oblong, crenately lobed 

 to nearly entire, 5-12 mm. long: flowers in short racemes; pedicels short, 

 rarely exceeding the calyx in length: sepals linear, obtuse, at maturity about 

 4 mm. long: corolla equaling the calyx-lobes: capsule exceeding the calyx at 

 maturity: ovules usually 10; seeds brown, irregularly ovate, obliquely rugose, 

 2 mm. long. In the Green river cliffs, Wyoming. 



2. Emmenanthe salina A. Nels. 1. c. 45. Similar but even smaller, some- 

 what viscid-pubescent: leaves oval to oblong, entire to pinnately lobed: 

 corolla minute, narrow, distinctly shorter than the 3 mm. long linear sepals: 

 capsule shorter than the sepals; seeds pale, oblong-flattened, transversely 

 rugose and obscurely reticulated. On the naked, ashy, alkali flats of Bitter 

 Creek, Wyoming. 



7. NAMA L. 



Low herbs, with purple, bluish, or white corolla. In ours the corolla is 

 short-funnelform and hardly exceeding the calyx, the flowers are in the forks 

 of the stem, and the leaves are entire. Ovary imperfectly 2-celled; styles 2, 

 distinct. 



1. Nama angustifolium (Gray) A. Nels. Erect, 1-2 dm. high, minutely 

 pubescent, glandular; stem repeatedly forked and with a nearly sessile flower 

 in each fork: leaves narrow, linear or nearly so: sepals narrowly linear: seeds 

 marked with about 5 longitudinal rows of large pits, from 4-6 in each row. 

 N . dichoto mum angustifolium. Gray, Proc. Am. Acad. 8:284. 1870. (Mari- 

 launidium angustifolium Kuntze.) Colorado and New Mexico. 



100. BORAGINACEAE A. Gray. BORAGE FAMILY 



Chiefly rough-hairy herbs, with alternate or rarely opposite entire leaves 

 and symmetrical flowers mostly on one side of the branches of a reduced cyme. 

 Calyx 5-parted. Corolla regular, 5-lobed. Stamens 5, inserted on the corolla- 

 tube. Style single; ovary deeply 4-lobed (occasionally undivided), forming 

 in fruit 4 (or by abortion fewer) seed-like nutlets, each with a single seed. 



Ovary undivided or only 4-grooved, with terminal style. 



Style 2-cleft or 2-parted 1. Coldenia. 



Style entire or none; stigma annular ...... 2. Heliotropium. 



Ovary 4-lobed or 4-divided, with central style. 



Nutlets armed with barbed prickles; fruit bur-like .... 3. Lappula. 



Nutlets unarmed <,r the prickles (if any) not barbed. 



NuUete widely divaricate, bordered with uncinate prickles . . 4. Pectocarya. 

 Nutlets attached laterally to a pyramid-like projection of the 



receptacle, 



Annuals. 



Leave* opposite below 0. Allocarya. 



Leaves all alternate . 7. Cryptanthe.
