fifth gland replaced by a shallow unoccupied sulcus. Seeds pink- 

 ashen, sharply triangular .9 x .6 mm., the dorsal facets slightly con- 

 vex, the ventral as slightly concave, all marked by 5-6 sharp trans- 

 verse ridges, two or sometimes three of which anastomose, and all 

 include the angles. 



Infrequent at Walsingham, Bermuda (114), at Catano, Porto 

 Rico (334), and on the south shores of Culebras Island (1779). 



EUPHORBIA PERGAMENA Small Bull. Torr. Club, 25:615. 



Plentiful at the base of trees, stumps and stones near the sea at 

 Pedernales Point, Isle of Pines (1436, 1442, 1443). 



The following characters drawn from the type, collected at 

 Miami, Florida, November, 1878, by Dr. A. P. Garber and distribu- 

 ted as E. albomarginata, should be added to Dr. Small's description: 



Stipules linear, entire, about twice the length of the petioles; 

 fifth gland represented by a broad and deep triangular sulcus flanked 

 by larger triangular involucral lobes, and the glands next each of 

 these lobes long-appendaged with large oblique (auricular) and some- 

 what irregularly crenate appendages. Seeds ashen, .85 x. 6 mm., 

 strongly tetragono-pyramidal, slightly curved ; facets transversely 

 deep 4-sulcate and 5-ridged, the ridges affecting the angles. 



The affinity of this species is close to E. adenoptera, as it comes 

 under Boissier's sub-section ff Involucri appendices superiores (exteri- 

 ores), bince, obliques, auriformes, duabus inferioribus nnilto rnajores. My 

 specimens from the Isle of Pines differ much in general habit among 

 themselves and from the type, and the leaves are considerably less 

 strongly serrate, yet they are good examples of the species. 



EUPHORBIA TRICHOTOMA Kth., H. B. K. , Nov. Gen. 2:60. 



The true form of the species very bushy and exuberantly leafy, 

 making a compact mass. Involucres scarce, appearing near the ends 

 of the branchlets. Leaves thin, spatulate, serrate at the blunt apex ; 

 glands large, yellow, ostreaform, slightly crenulate on the free mar- 

 gin; lobes deltoid, slightly hairy. Capsules minutely tuberculate- 

 scabrous. Seeds globular, 2x2 mm., the surface densely covered 

 with very minute circular maculae. East shore of Cozumel Island, 

 near the northeast point (1600), and the north and south shores of 

 Cayman Brae (1185, 1232); not found elsewhere on the coasts. 



Euphorbia trichotoma macilenta var. nov. 



Similar to the species, but of open, scraggy growth. Leaves 

 thicker, appearing like those of E. buxifolia; serration finer and less 

 evident. Seeds triangulo-globular 1.9 x 1.8 mm., nearly smooth on 

 all facets. Cape Corientes, Cuba, rare (1447, 1463); east shore Cozu- 

 mel Island, rare (1598).

 EUPHORBIA PEPLUS Linn., Sp. 658. 



Three forms of this species exist on the Bermudas, the one branch- 

 ing and leafy from the base (Hamilton, 135); another with a nude 

 main stem 6-8 in. long and with the umbellate branches nude below 

 and small-leaved above (Walsingham, 73), and the third a low form 

 with lower leaves in part orbicular broad, and shorter petioled than in
