SANDWICH ISLANDS. 
[Convolvulacece. 
(Gaud, iu Freyc. Voy. p. 98,) is the same, since no description has been given. Mr. Brown takes notice of 
two other species found in the Sandwich Islands, both with the segments of the corolla quite naked ; these, 
however, we have not seen. The habit of our plant is so similar to Leucopogon obovatus, LabiU., that 
Sprengel has united them without attending to the position or number of the bracteie at the base of the calyx. 
Ord. XXVIL APOCYNEiE. Juss. 
1. Alyxia sulcata \ foliis oppositis ovatis obtusis submembranaceis utrinque nitidis 
obsolete parallelim venosis, pedunculis axillaribus solitax’iis 3-floris folio dimidio brevioribus, 
fructibus olivaeformibus longitudinalitei' multi-sulcatis. 
This is a very handsome species, and perhaps, as we at first thought, the A. olivaformis of Gaudichaud 
(Freyc. Voy. p. 451,) found in the same islands; but there are too many points of discrepancy to allow 
of our joining them. The leaves are never, that we see, in threes; nor are they acute at both extremities, 
as in Gauchchaud’s plant ; nor do we thiiilv he would have neglected to notice the numerous longitudinal 
furrows on the fruit. From A. scandens, Forst., this differs in many respects, particularly in the furrowed 
fruit, which has a perfectly even smface in that species ; a character we omitted to remark at page 66, from 
not being at that time acquainted with the present plant. 
1. Cerhera parvi/lora ; foliis quaternis oblongis obtusiusculis parallelim venosis planis, 
cymis peduncidatis axillaribus ramosis divaricatis. — Forst. Prodr. n. 121.” Willd. Sp. PI.

This species is omitted by Sprengel, and placed by Willdenow and subsequent authors among the doubtful 
species. It is very closely allied to C. maculata, WiUd., nor can we easily point out any character to 
separate the two, except the shape of the leaves, which in our plant are very much broader, and not at all 
spotted, as is weU represented in the other species by Jacquin, (Ic. Rar.ii. t. 321.) There ai’e constantly foiu- 
leaves in each whorl. The bracteas are small, and, towards the base, furnished with several spinous processes, 
or teeth.

In the specimens before us, the branches .are long and slender, from which we might almost conclude 
the plant to have been prostrate and not erect. We possess, in oiu* herbarium, a plant from Mr. Menzies, 
also from the Sandwich Islands, which is a rem.arkable variety of the present species, being densely pubescent.
