the lons^er ones 2-2.5 cm. long; bud ovoid, prominently long-

 fruit yellowish, ellipsoid, about 8 cm. long, 5-6 cm. thick, rounded

Description from N. Y. B. G. no. 2614, collected at George- 

 town, Long Island, Bahamas, by N. L. Hritton and C. F. Mills- 

 paugh, in 1907 {no. 6jj/). 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. /lo. 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 («<?. jS), 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- 

 tiss' N. A. Plants no. g6j, 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 Cerciis vionoclonos, but it is not C. mono- 

 clonos of De Candolle. 



8. Harrisia Taylori sp. no v. 



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

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

 ribs rounded, the depressions between them rather deep. Areoles 

 2-3 cm. apart; spmes 9-12, the longer 3-5 cm. long, ascending ; 

 bud globose-ovoid, short-pointed, its scales with sparse curled 

 grayish-white wool 3-6 mm. long.

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