 Native of South America; leaves opposite, generally simple and 

 terminal ; panicle of bright blue flowers lighter in the throat of the

16. D Plumieri. — The difference between this and the former 

 is not easily detected, both are stout, subarboreous species, often 

 armed with long thorns, and form a very ornamental hedge division 

 in a garden. We have received a third (D spinosa) with white 

 flowers, from Paiell gardens, very thorny. The contrast of the green 

 of the leaves, and the vivid yellow of the clusters of acuminated 

 fruit, is very pleasing.
