a reference in Linnaeus's hand to Browne's diagnosis (quoted above)* 

 but not otherwise determined by Linnaeus. The specimen includes 

 no Mower or fruit, but from Browne's description and figure of 

 the Hower together with the leaf in the herbarium, we have no hesita- 

 tion in identifying it with Zanthoxylum flavum Vahl. (Fawc. & 

 liendle, Flor. Jam. iv. 173).

Hub. Troy, 2500 ft. Harris, 9349 ! 



Near G jamaicensis Britton, but distinguished by the leaflets 

 being in fewer pairs, and having an unequal base. 



The following is a key to the species from Jamaica so far as 

 known to us : — 



Leaflets entire, not undulate, nor toothed. 

 Plants glabrous, or more or less hairy. 

 Leaflets in 6-8 pairs, upper usually more 

 than 5 cm. 1. 

 Leaflets with truncate or rounded base. 1. C. pinnatifolia. 



Leaflets with cordate base 2. G cor data. 



Leaflets in 3-5 pairs, upper usually less 



than 5 cm. 1 3. C. parvifoliola. 



Panicle, twigs, and leaves brown-velvety ... 4. G velutina. 

 Leaflets toothed or undulate. 

 Leaflets with large coarse teeth. 



Leaflets in 8-10 pairs, apex acute to 



shortly acuminate 5. G Hollickii. 



Leaflets in about 14»pairs, apex ending 



i n a long slender acumen 6. G. gran did en fata. 



Leaflets with small shallow teeth. 



Leaflets in 10-11 pairs, base subequal ... 7. C. jamaicensis. 

 Leaflets in 6-8 pairs, base unequal 8. G troi/ensis. 



Note.- — Under G pinnatifolia we include provisionally G pilosa 

 Britton and G pubescens Engler, specimens of which we have not 

 seen. The considerable series which we have examined includes 

 glabrous specimens and others with varying degrees of hairiness. 



AQUIFOLIACE.E. 



Ilex florifera, sp. nov. Arbor usque 40 ped. alta, glabra, ramulis 

 cinereis. Folia 6-10 cm. 1., 4-5-8 cm. lat,, rotundato-elliptica, 

 integra, margine subrevoluta, apice et basi rotundata, coriacea, costa
