March, 1900. Plants Utowan^e Millspaugh. 61 



larger than in the species and hairy within, lobes broadly deltoid 

 ciliate, appendages creamy, larger than in the species, somewhat 

 flabelliform and more sarcous. Seeds 1.2 mm. x .9 mm. {smaller 

 than in the species), the reticulations much more strongly marked. 

 Southwest Point, and southern shores of Cayman Brae (1196, 1233). 

 Scattered and infrequent. 



Euphorbia buxifolia ramosissima var. nov. 



Erect, profusely short branched from the base appearing like a 

 ball when growing. Leaves exceeding numerous, small, 7 x 3.5 mm. 

 obliquely auriculate-cordate at base, absolutely entire at the simply 

 acute apex. Involucres usually sparse, pedicels as long or longer 

 than the involucre which is of the size of the species, glands smaller, 

 appendages larger, hairiness of internal surface of involucre pro- 

 nounced but not so marked as in var. flexuosa Boiss. Seeds 1 x .7 

 mm. smaller than the species or var. flexuosa, dorsal angle forming a 

 prominent keel, reticulations barely visible. The Creek, Cayman 

 Brae (1180), Georgetown, Grand Cayman (1262). Not plentiful at 

 either place. 



All the forms of E. buxifolia prefer a locality where the wind 

 sweeps free from the open sea. They are rarely found at all on the 

 sandy shores of bays or straits. Careful search of the shores of San- 

 tiago and San Juan bays failed to yield a single specimen. 



Euphorbia pilulifera L., Am. Ac. 3:114. 



The usual erect form with broad and large leaves was taken at 

 Catano, Porto Rico (329), and Charlotte Amalia, St. Thomas (489, \/ 

 490); and the narrower leaved form having a tendency to being simple 

 stemmed, at Catano, Porto Rico (1775); Charlotte Amalia, St. Thomas 

 (426, 396), and San Domingo (846). 



Euphorbia pilulifera discolor Engelm., Bot. Mex. Bound. 188. 



Although included under the species by Boissier, 1 consider this 

 form of sufficient persistence to constitute a good variety, with its 

 lurid-maculate leaves, extreme obliquity of leaf base, and ascending 

 habit. Santiago de Cuba (1063) and Port Antonio, Jamaica (949). A 

 form of this variety having all the characters except the maculation 

 was taken at Cayman Brae (1175). 



Euphorbia pilulifera procumbens Boiss., in de C. Prod. xv:2i. 



This pronounced variety with its bifurcating branchlets, small 

 short-petioled strigose-hairy leaves, taken at Hamilton, Bermuda (124); 

 Spot Bay, Grand Cayman (1292, 1298, 1213), and on Culebras Island 

 (567), where it is very plentiful in the open grounds near the little set- 

 tlement on the south shore. 



Euphorbia Cozumelensis sp. nov. Plate lxiii. 



Annual, prostrate, or erect when growing among grasses, glab- 

 rous; stems many, ligneous, internodes short; stipules deltoid lace- 

 rate on the outer margin; stems and branches densely leafy, leaves 

 oval or ovate, strongly oblique, and sharply dentate, especially at the 

 apex and along the lower margin, mostly lurid above and pale whitey- 

 green beneath. Inflorescence in sessile few flowered terminal clus-
