(Spruce, 3167). 
This is a well-marked species, having greatly the aspect of an 
Anelasma, under which name {Abuta) it was distributed ; when 
observed carefully, the ditference is very manifest, especially in 
the nervation of the leaves. The axils are 1-1 1 inch apart; the 
leaves are 4 inches long. If inch broad, with a narrow acumi- 
nate point I inch long ; they are deeply channelled both at the 
base and apex ; the petiole is 1 inch long. One or two very 
elongated panieles grow out of a supra-axillary villous tuft ; the 
rachis is 9 or 10 inches long; and from it, at alternate distances 
of about ^ ineh, two capillary, patent, laxly ramified branches 
are emitted, about 1 ineh long, the pedicels being 1| line long, 
and the flower expanded 1 line in diameter ; they have six gla- 
brous membranaceous sepals, imbricated in aestivation, the three 
inner ones being the larger ; six flat cuneately oval petals, some- 
what smaller; six stamens, of equal length; filaments com- 
pressed, suddenly widened at the summit ; anthers bilobed, the 
diverging lobes being laterally adnate and separated by the 
connective, each bursting by a longitudinal fissure; three punc- 
tiform rudiments of ovaries are seen on the summit of the short 
columnar androecium, to which the stamens and petals are 
attached. 
Dr. Eichler,. while he considers the above plant identical with 
H. Domingensis (from which it is widely distinct), strangely 
amalgamates all the following species with the same, under the 
name of Pachygone Domingensis, — thus confounding not only 
many difierent species, but mistaking one genus for another.
