long, with a lengthened acumen, base acute, the upper 
surface pubescent, the under one with numerous opposite, 
oblique, parallel nerves, which, together with the strong 
rib and reticulate veins, are villous. ^ Petioles very short. 
Stipules broad and short, adpressed, soon withering, ending 
in a subulate acumen, at the base of which there are on 
each side one or two crenatures. Inflorescence most ample, 
densely villous, especially the corols, which are of a de- 
lightful sky-blue colour. Ovarium somewhat 5-cornered. 
In every other respect the two plants agree. How far 
mine should be considered as a variety only, or a distinct 
species (which I would propose calling S. azureum), I must 
leave undecided, until the young plants, which were brought 
down with me, shall come to a proper age. It is worth 
observing, that all its tender parts and the flowers, on being 
bruised, as also in decaying, emit a peculiarly fetid smell, 
precisely as is the case with similar parts of Serissa and 
Pederia fetida, and some others. When out of flower 
the shrub looks for some time peculiarly withered and poor, 
In consequence of the unusual time during which the dried 
brown panicles remain on the branches." 
Such is the account given of this in the second volume of 
the Flora Indica, published in 1824. Upon what ground 
Mr. Don altered Dr. Wallich's name azureum to that of 
scabrum, we do not understand; nor why he altogether 
omitted the Flora Indica synonym of Sp. azureum. With 
regard to the name Hamiltonia, applied to this genus by 
Dr. Roxburgh, we are clearly of opinion that Spermadictyon 
is preferable; not that we admit any right on the part of 
Willdenow to change Michaux's name of Pyrularia for that 
of Hamiltonia, but that it is now too late to remedy the 
act; Hamiltonia is at this day universally applied to the 
American genus, and cannot without inconvenience be 
removed: besides, we think that some attention is due to 
the opinion of Mr. Brown, with whom the name of Sperma- 
dictyon, which, by the way, is unexceptionable, originated. 
There can be little doubt that Dr. Wallich's Lepto- 
dermis, combined by Mr. Don with this genus, is distinct : 
the curious manner in which its bractea are formed, and 
the whole habit of the plant, forbid such a combination. 
Our drawing was made in January last, in the Garden 
of the Horticultural Society, from a plant presented by the 
Honourable Court of Directors of the East India Company.
