'* NORTH AMERICAN 



pear types of two subgenera differing 

 tenis and Aureolaria. 



407. M AC R ANTHER A LEcoNTi Torrey (or 

 Toxopus gymnanthes Raf.) leaves smooth pe- 

 tiolate ovate lanceol. sinuate pinnatifid, bracts 

 and segments of calix linear lanceolate entire 

 in Florida and on the R. Alatamaka, 2 or 3 

 feet high, flowers autumnal deep yellow. Tor- 

 rey states the stigma to be simple and yet his 

 figure shows it quite bifid and bilamellar. 



408. MACK ANTHER A FUSCHIOIDES T. Benth 

 (or Toxopus calycinus or Tomilix bracteata 

 Rat) Conradia Nut. rar. 41. fig. Smooth 

 leaves petiolate lanceolate sublyrate pinnatifid, 

 bracts ovate sinuate, segments of calix lanceo- 

 late unequal foliose serrate in" Alabama, fine 

 large plant with golden flowers, the calix is 

 nearly as in Panctenis, and the stigma certain- 

 ly simple, these two characters indicate a sub- 

 genus if not a Genus ! my Tomilix meaning cut 

 calyx. 



409. APENTOSTERA Raf. (no fifth ste- 

 rile) Calix Sparted subequal, corolla ventricose 

 campanul. bilabiate, upper lip erect bilobe, low- 

 er trilobe. Stamens 4 didyn. anthers villose, 

 no fifth sterile filament. Capsule ovate acute, 

 seeds angular not winged. Leaves opposite, 



flowers axillary, racemose purplish this N. 

 *Gr. of Origon is probably fecond in sp. It links 

 the Gerardia group with the Pentostemon. 

 Totaly unlike our real Chlonanthus (chelone) 

 having the corolla convex short and winged 

 seeds. Pentostemon which now includes a 

 crowd of sp. that must be divided into 5 Gen- 

 era, differ by the fifth filament and various co- 

 rollas. Also near to Pagesia.
