﻿614 Small : Botany of Southeastern United States 



vate-oblong or cuneate, 1-3 cm. long, obtuse or notched at the 

 apex, with a stout midrib, sessile or short-petioled : involucres 

 scattered along the slender branchlets, campanulate, with a trun- 

 cate base about 1 mm. high, angled at maturity : glands trans- 



versely oblong, about 0.5 mm. broad; appendages ascending, 

 white, r mm. long, orbicular-cuneate, minutely erose at the top. 



In sandy soil, southern Mississippi. Summer. 



Related to Eupliorbia apocynifolia but the foliage is perfectly 

 glabrous and the stems very rigid. The plants are conspicuous 

 on account of the numerous leaves on the stem and the many 

 small thick broad bracts scattered on the elongated branches of 

 the inflorescence. A good character is furnished by the invo- 

 lucres ; these are truncate at the base. I am not aware that this 

 character exists in any other member of the group. The original 

 specimens were collected by Prof. S. M. Tracy at Biloxi, Missis- 

 sippi on July 15, 1894, nos. 2883 and 2885. 



Euphorbia eriogonoides. 



Perennial, deep green, glabrous. Stems several cr many to- 

 gether, 1-3 dm. long, diffusely branched into a rounded head 1-3 

 dm. in diameter; branches very slender, zigzag, widely dichotomous, 

 ultimate divisions nearly filiform : leaves opposite, above first fork, 

 reflexed or deflexed ;* blades linear or linear spatulate, .5—1.5 cm. 

 long, obtuse or acutish, entire, barely petioled : peduncles filiform, 

 3-8 mm. long at maturity : involucres campanulate with a rounded 

 base, less than 1 mm. high, erect or ascending : glands reniform, 

 about 0.5 mm. broad; appendages ascending, reniform -cuneate, 

 white or pink, about 1 mm. broad, 0.5 mm. long, longer than the 

 gland, some truncate, some cleft : capsules not seen. 



In loose sand, eastern Georgia. Spring and summer. 

 A very characteristic species on account of its close resemblance 

 to Eriogonum cernuum and some of its relatives. The stems are 

 diffusely branched from the base and the branches thence widely 

 dichotomous. The leaves at the nodes are reflexed or deflexed 

 and often curved. The very numerous involucres are less than 1 

 mm. high, while the white or pink appendages are only about O-S 

 mm. long and about 1 mm. broad. The small size of the members 

 of the inflorescence and the characteristic habit separate it from all 

 other species of Tithymalopsis. The original specimens were col-
