leaves lauceolate acuminate, 8x2.5 cm., light green, glabrous (ex- 

 cept the juvenile), flower heads sessile, a large shrub (1012). Shores 

 of Spot Bay, Grand Cayman, resembling the last, but with smaller 

 leaves (5.5x2 cm.), and peduncles from .5 to 2 cm. long. A fair 

 size shrub, 1.5 to 2.5 meters (1306); specimens from Pedernales Point, 

 Isle of Pines (1428), are counterparts of this form. Three individ- 

 uals of this species were found upon the south shore of Perez Island, 

 Alacran Shoals, the largest of which I cut down for the woody por- 

 tion. In these the leaves are small (4.3x1.5 cm.), and the head 

 short peduncled. Low shrubs (1 to 2 meters) established at this 

 habitat 19 years according to the woody rings of the largest (1755). 

 [Specimens in this Herbarium from Socorro Island, off Lower Cali- 

 fornia [Anthony, 397), have leaves 8x 2.4 cm., and peduncles (in fruit) 

 of the length of the cones; from Acapulco, Mexico {Palmer, 137), 

 leaves 9.5x2.5cm., peduncles one-third the length of the fruiting 

 cones; from Biscayne Bay, Florida {Palmer, 159), leaves 5.5x1.4, 

 peduncles 1.3 times the length of the heads: and from Indian River, 

 Florida, [A. H. Curtiss) with leaves elliptical-acuminate, 6 x 2.7 cm., 

 and peduncles of the length of the flowering heads.] 



Conocarpus erectus arboreus Griseb. Fl. Br. W. I. 277. 



In this form the leaves are more broadty lanceolate, more inclined 

 to be sericeous, obscurely petiolate, whole plant arboreous. Tree 

 9 meters, very abundant at the port of Silam (642 Gaunter), leaves 

 10. 5 x 3 cm., peduncles about one-half the length of the ovate flower 

 heads. 



Conocarpus erectus sericeus (Forst.) Griseb. Fl. Br. W. I. 277. 



C. sericea Forst. An erect shrub with broadly lanceolate leaves 

 covered with a light but persistent silky down, and with fruits twice 

 the size of the species. Shores of the east coast of Cozumel, shrub 

 3 meters, leaves downy, 8.5 x 3.3 cm., fruits globular 1.5 cm. diam. 

 sessile (1582). [Shrub 5 meters, coast of Yucatan at Progreso, like 

 the last but with smaller leaves (6 x 2.5 cm.). Collected by Gaumer, 

 1 164; and by Dr. Arthur Schott 264, 266.] 



Conocarpus erectus procumbens (Linn.) Jacq. Am. Pict. 260, f. 22. 



C. procumbens Linn. A prostrate trailing shrub bearing but little 

 resemblance, in the field, to the species, even when growing together 

 as is often the case; the stem trails along the surface of the ground 

 and the flowering branchlets become erect as they are produced. The 

 leaves are thicker than in the species, ovate, and mucronate, the 

 fruit large and sessile, and the stamens usually 2. Islets in Hamil- 

 ton Bay, Bermuda, leaves 4.7 x 2.2 cm., sharply mucronate, fruits 1 

 cm. diameter (11); shores at San Miguel, Cozumel, leaves 5 x 2.6 cm., 

 sharply mucronate, (1472); shores of the lagoon south of Progreso, 

 Yucatan, like the last but less mature (171 7, 1720). 



Conocarpus erectus argenteus var. nov. 



A striking tomentose variety of the prostrate form, with broadly 

 ovate acute densely si.lvery-villous leaves and sessile fruits. South- 

 west Point, Cayman Brae, leaves 8 x 4.7 cm. (1212); east shore of
