NORTH AMERICAN 
pear types of two subgenera differing as Pane - 
tents and Aureolaria. 
407. Mac r anther a leconti Torrey (or 
Toxopus gynmanthes Raf.) leaves smooth pe- 
tiolate ovate lanceol. sinuate pinnatifid, bracts 
and segments of caSix 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 
Raf) 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 5parted subequal, corolla ventricose 
campanula 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. 
G. 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.
