B. frutescens, DC. Less woody, more permanently canescent ; the simpler stems 1 to 3 feet

99. BALSAMORBHfZA, Hook. (BaXo-a/Aov, balsam, pi'£a, root.) — 

 Low perennials (all of Central and "Western N. America) ; with thick and deep 

 roots, which exude a terebinthine balsam, and send up a tuft of radical leaves, 

 mostly on long petioles, and short simple few-leaved flowering stems or naked 

 seapes, bearing large and mostly solitary heads of yellow flowers ; the rays ample 

 and numerous. Cauline leaves when present alternate or occasionally opposite, 

 petioled. The root, when peeled (to get rid of the terebinthine rind) and baked, 

 is an article of food to the aborigines, and the akenes are also eaten. — Fl. i. 

 31Q (under Heliopsis) ; Torr. & Gray, Fl. ii. 300; Gray, PI. Fendl. 81. 



§ 1. Ligules becoming thin-papery, and persistent on or very tardily deciduous 

 from the canescently pubescent akenes. — Kalliactis, Gray, 1. c. 

 B. Careyana, Grat, 1. c. Cinereous-pubescent, slightly scabrous : flowering stems a foot 

 high, bearing 3 or 4 small lanceolate leaves and 2 to 7 racemosely disposed heads : leaves 

 subcoriaceous, entire, reticulated ; the radical cordate-lanceolate, a span or more in length : 

 involucre half-inch or more high : ligules oval, hardly inch long, abruptly contracted into a 

 very short but distinct tube: style-branches of the disk-flowers subulate and very hispid 

 throughout. — Sandy plains on the Clearwater, Idaho, fl. May, Spalding. Eediscovered on 

 the Wallawalla, Washington Terr., 1883, by Brandegee, with the rays deciduous from the 

 mature fruit. 



§ 2. Ligules deciduous in the ordinary manner : akenes glabrous : stems or 

 scapes terminated by solitary or sometimes 2 or 3 heads.
