 Kuntze, J. nubica Hochst, Port Antonio, Jamaica (967), also found

JUSSIEUA OCTOVALVIS (Jacq.) Sw. Obs. Bot. 142. 



Oenothera octovalvis Jacq. Enum. PL Carib. , 19., J. salicifolia 

 Kth., J. angustifolia Lam. In the Index Kewensis this species is 

 included under the next, from which, however, my Jamaican forms 

 are plainly distinct, the leaves being longer, far narrower and sharper 

 pointed, the calyx lobes lanceolate, the fruits much larger, longer, 

 and not subtended by the two awl-shaped bracts at the apex of the 

 pedicel. Port Antonio, Jamaica (926).

UMBELLIFERACE^E. 



Hydrocotyle Yucatanensis sp. nov. 



Glabrous radicant, leaves peltate in the middle, orbicular, 2.5- 

 3.5 cm. diameter, widely and slightly crenate, veins 14-15, pedun- 

 cles 12-27 cm., mostly longer than the petioles; umbels proliferous 

 expanded, many flowered, the secondary umbels usually capitate, 

 terminating the pedicels, flowers yellow, fruits truncate at the base, 

 2.3 mm. broad, .7 mm. long, carpids 3-ribbed, the intermediate 

 prominent, the lateral corky. 



Muddy banks of a dried-out lagoon about 4 kilometers south of 

 Progreso, Yucatan (1677). The long strictly-erect scapes and pe- 

 tioles, yellow flowers, and venation of the leaves, immediately sep- 

 arate this species from its cogeners. Type in Herb. Field Col. Mus. 

 Cat. No. 61677.
