DEC., 1913. EUPHORBIACE.E MILLSPAUGH 365 



Cymes trichotomous ultimately 3-cephalic; peduncles 1-2 cm. long, 

 slender, finely puberulent; bracts i .5 x .8 cm., oval, acute, slightly exceed- 

 ing the peduncles; involucres puberulent, 1.5 x .6 cm., the superior 

 fissure closed to the throat by the connate lateral and fifth lobes; tube 

 short, deeply notched beneath, projecting narrowly backward to sup- 

 port the long appendix; main lobes broader than long, the apex rounded, 

 each with a projecting deltoid tooth connate with the lanceolate, acute, 

 lateral lobes which, in turn, are connate with the ligulate, truncate, 

 fifth lobe so that all together entirely close the usual superior fissure of 

 the tube, all three minor lobes are free at their apices the fifth being 

 slightly longer than the lateral; the notch of the tube has three to four 

 raggedly-deltoid teeth at the base of its sulcus; male pedicels glabrous, 

 female puberulent. Appendix as long as the tube, projecting poste- 

 riorly half its length and extending anteriorly along the margin of the 

 fissure to the throat, split its entire length into two separate, linear lobes 

 folded upon themselves upward like a trough; glands 4, of two sorts, 

 circular with raised thickened margin : two single ones placed flat against 

 the walls of the gibbum, two double ones placed back-to-back at the 

 summits of long stipes connivent with the walls at the base of the 

 linear lobes (these latter resemble stamens with ruptured, 2-celled 

 adnate anthers).

21. PEDILANTHUS TOMENTELLUS Robn. & Greenm. Am. Jour. Sci., 



50:164. 1896. 



Tall, 1.5-2.4 m., rusty-tomentulose ; branches stout, terete. Leaves 

 short petioled, ovate-oblong to oblong-lanceolate, narrowed at both 

 ends, obtusish, tomentulose upon both surfaces, 4.8 cm. long, 2.4 cm. 

 broad. Cymes terminal, twice dichotomously forked, about 5 cm. 

 diameter, outer floral leaves and those of the forks large, bright red, 

 sessile, broadly ovate or suborbicular, cordate, shortly acuminate, 

 tomentulose, 2.4-3 cm - l n g> enclosing the smaller bracts and the 

 involucres thus giving the cyme a somewhat 2 -cephalic appearance. 

 Involucres 1.2 cm. in length, tomentulose throughout, unequally 

 5 -cleft at the throat the divisions rounded to sub-truncate with an 

 erose or fimbriated margin, the three interior much smaller, linear- 

 oblong; pedicels of the staminate flowers glabrous, filaments and 

 anthers pubescent; pedicel ovary and style of the pistillate flowers 

 ferrugineous-tomentose ; style 5 mm. long the three divisions 2 -cleft. 

 Appendix deeply 2-cleft the lobes about 7 mm. long, lanceolate, obtuse, 

 thickened at the apex; glands 2 or 4.
