 carpels each prolonged downward into two conical horns; seeds globose- 

 lenticular, 7.5 mm. diameter, rusty-brown, smooth, apiculate. Appendix 

 fleshy, slightly shorter than the tube (usually about one half its length) , 

 deeply cleft into two ligulate, laterally compressed, bi-geniculate lobes 

 turned upward at the rounded apex; glands 8 (often by abortion 6} in two 

 sets of four each at the bases of the lobes. (Characters in italics drawn

29. Pedilanthus peritropoides Millsp. sp. nov. 



Shrubby, glabrous. Leaves sessile, 12-15 cm - l n g> 5~6 cm. broad, 

 thin, ample, glabrous, oblong to ovate, rounded and often emarginate 

 at the apex, cuneate at the base, the midrib keeled for its lower third 

 beneath. Inflorescence terminal, cymose, crisp-pubescent, bracteate; 

 bracts oval, pointed, 1.8 x 1.5 cm., as long as or slightly longer than the 

 peduncles. Involucre 2x1 cm. crispidulous-puberulent without, gla- 

 brous within, the tube broad and truncate anteriorly; main lobes ovate, 

 pointed, entire; the three accessory lobes short, flabellate, equal, free 

 at the ciliate apex only; male pedicels numerous, glabrous; female crisp- 

 puberulent throughout; style 3-parted at the apex, stigmatic branches 

 bi-lobed. Appendix small, about one third the length of the tube, its 

 lobes entirely concealed within the wing-margined fissure of the tube; 

 lobes 3, the superior pair ligulate, the margins folded upward upon them- 

 selves like a trough, the third lobe elongated-linear with a deltoid base, 

 all crisp-puberulent ; glands 4 at the gibbum: one pair at the inner 

 bases of the superior folded lobes the other pair on the walls of the gib- 

 bum beneath the base of the third lobe. 



The involucres, with their large, rounded anterior end, appear as if 

 reversed from their usual form, the posterior exactly resembling the 

 usual anterior extremity. The male flowers are exserted upward in a 

 plumelike fascicle from the fissure instead of forward, as usual, along the 

 female pedicel.
