the remainder of the Monocotyledons. It is estimated that the Dicotyledons 
will be completed in four volumes, making the completed work contain six 
volumes. Preceding the presentation of the families, there is a list of works 
referred to in the text, a list of names of collectors with the dates of their col- 
lections, a conspectus of the families, and a key to families. 
The contrast with north temperate floras is striking. Out of 38 families 
presented, such conspicuous northern ones as Caryophyllaceae (7 spp.), 
Ranunculaceae (4 spp. of Ranunculus and Clematis), Cruciferae (6 spp.), and 
Rosaceae (9 spp.) are negligible elements of the Jamaican flora; while the large 
families are Urticaceae (55 spp.) and Piperaceae (52 spp.), the largest genera 
being Pilea (42 spp.) and Peperomia (38 spp.). The genera number 115 and 
the species 347, so that, omitting the two large families, the genera average 
only two species each.—J. M. C
