petals being only slightly swollen. In A. scierocarpa the petals of the fruiting 

 perianth are strongly swollen, or conspicuously callous. In A. acidcata the 

 lower lip of the scrobicules is not much produced, while in A. scierocarpa it 

 is bracteiform or liguliform, and 4-5 mm. in length. The ovary in A. aculeata 

 is hairy from its base to the origin of the stigmas; in A. scierocarpa it is densely 

 hairy in its lower part only and glabrous above. The ring formed by the 

 staminodes in A. aculcata is perfectly truncate, while it is distinctly six-toothed 

 in A. scierocarpa. 



I have especially described the palm growing in Porto Rico known by the 

 vernacular name "Palma de Corozo", and of which Mr. 0. F. Cook has made 

 his A. media. I have, however, examined also numerous other .specimens col- 

 lected in various of the Greater and Lesser Antilles, which all seem to me 

 referable to A. aculeata. 



From Porto Rico I have seen : Sintenis n. 3972, 4935, 6483 (Herb. Berol.) 

 Bertero also collected this palm in Porto Rico and fragmentary specimens of 

 it are preserved in the Herbaria de Candolle and of Berlin. In the latter, one 

 specimen bears the n. 286, and comes from the Herbarium Sprengel ; another 

 comes from the Herbarium Kunth ; all are labelled Cocos aculcata. 



Jamaica: Harris n. 9943 (Herb. Berol.) near ]\Ialvern, 730 m. alt.; the 

 f^o^^'ering branchlets are exactly as in the plant of Porto Rico. 



Haiti : In the plain near St. Michel leg. W. Buch 1907 (n. 3 in Herb Krug 

 et Urban). Habitus Orcodoxce rcgia- Fructus flavi, edules. The fruits are 37-40 

 mm. in diameter. The seed is 26 mm. broad, 23 mm. high. The fruiting 

 perianth is exactly as in the plant of Porto Rico. 



Tobago: Eggers n. 5739 (Herb. Berol.) "Grougrou" incol. Common on 

 the River Bacolet. The fruit is said to be 38 mm. in diameter, and to be edible ; 

 the specimen has only a portion of a leaf, corresponding to those of the plant 

 of Porto Rico. 



Guadeloupe: Pere Duss n. 3805 (Herb. Berol.) Plains and marshes of 

 the Lamentin, Vulgo "Dinde". The flowers and fruits, 4 cm. in diameter, are 

 exactly like those of the plant of Porto Rico. In a note Pere Duss describes the 

 leaves as 3-4.5 m. long with segments on two series; the entire plant 10-17 m. 

 high with a straight trunk; this is swollen at the base in young individuals, 

 but in the middle in those older, and in the very old ones near the summit; 

 the trunk is marked by annular rings, and furnished with spines. The spadices 

 are at first erect, then recurved, 1 to 1.30 m. in length, and bear 80-100 

 flowering branchlets. The flowers are yellow and exhale a bad smell. An 

 entire spathe is 1.20 m. long, very densely velutine, quite devoid of any kind 

 of spines. 



Dominica: Eggers, ^March 1882, "Grou-Grou" inc. (H. Berol.), only 

 leaves of young plants which do not show differences from analogous leaves 

 of the same age from Porto Rico. Also Eggers, Goodwill Valley, 23, 2, 1880, 

 as above. 



Martinique: Pere Duss, Riviere Salee, Ducos, Lamentin, vulgo "Glou- 

 glou" (Herb. Berol.) Leaves as in the plant of Porto Rico. The spathe
