A 



paugh, in 1907 (no. 6 337 ). Named in honor of Hon. Herbert 

 A. Brook, Registrar of the Bahamas, in recognition of his valuable 

 aid in our exploration of these islands. 



The plant of Florida, of which I do not yet know the buds 

 or the flowers, more closely resembles this Bahamian species 

 in its spines and areoles than it does any of the others here de- 

 scribed. Our living plant, N. Y. B. G. no. iggoo, was collected 

 by Prof. P. H. Rolfs on islands east of Malabar and brought to 

 the Garden by Dr. J. K. Small in 1903. As shown by an her- 

 barium specimen, prepared by Dr. Small at that time (no. 78), the 

 fruit of this species is nearly globular, about 5 cm. in diameter, 

 and apparently smooth or nearly so. We also have an excellent 

 Photograph, taken by Mr. C. L. Pollard on Key Largo ; and Cur- 

 Plants no. q6j, from a locality between the Indian 

 River and the ocean, is this same species, which is described in 

 Chapman's Southern Flora, at least in so far as the flower is con- 

 cerned, under the name Cerens monodonos, but it is not C. mono- 

 'lottos of De Candolle. 



8. Harrisia Taylori sp. nov. 



Plant light green, branched above, 1.5-2 m. high, the branches 



divaricate-ascending, rather stout, 4 or 5 cm. thick, 9-ribbed, the 



rounded, the depressions between them rather deep. Areoles 



"~3 cm. apart; spines 9-12, the longer 3-5 cm. long, ascending ; 



u " globose-ovoid, short-pointed, its scales with sparse curled 



grayish-white wool 3-6 mm. long. 



Description from N. Y. B. G. no. 25767, collected by Norman 

 aylor on the sea-beach between Rio Grande and Rio Ubero, in 

 In eastern Cuba, in 1906 (no. 253).
