A New Bahaman Euphorbia. — While on a trip from New 

 Providence to the Bimini Islands, anchor was cast for the night 

 in the creek separating the Joulter Cays lying north of the 

 island of Andros. The opportunity to examine into the flora 

 of these xerophytic cays was an excellent one and the results 

 proved highly interesting. One of the first patches of vegetation 

 to attract the attention was what appeared to be a growth of 

 Enpliorhia buxifolia Lam. in a new environment, namely the 

 interior, separated from the sands of the beach by a high bluff 

 of coralline rock. Closer examination of the plants removed 

 their likeness to the species mentioned, and later study proved 

 the species to be heretofore unknown. The characters : 



Euphorbia Cayensis sp. nov. 



§ Chamaesyce. Annual, densely white-canescent. Stems 

 stout, ligneous, multinodal, branching from below, 2—3 dm, 

 high, spreading above : leaves thick, oval, obliquely cordate at 

 the base, entire, canescent alike on both surfaces, 4-6 mm. x 3- 

 4 mm., short-petioled ; petioles i — 1.5 mm.: involucres campan- 

 ulate, short-peduncled, 1.5 mm., canescent, bearded in the 

 throat ; appendages lineal, hardly distinguishable ; glands green, 

 transversely oblong, thick, tumid, 0.7 mm. broad ; false gland a 

 large deltoid tooth of the involucre : capsule canescent, 2 mm., 

 the carpels bluntly keeled : seeds pinkish-ashen, somewhat quad- 

 rilaterally ovoid, strongly keeled on the dorsum, the facets 

 slightly anastomose-ridged.

TiiK EffI'XT of Illuminating Gas on Trees and Shrubs. 

 — I'^arly in the spring of this year about three dozen bushes of 

 Rosa riigosa were planted on both sides of the road near the 

 stone piers at the entrance to the New York liotanical Garden, 

 between the railroad bridge at 200th Street and the driving roads. 

 Those in tlie southern half promptly died, while those on the 

 north side have lived and arc doing well. This fact coupled with
