82 SANDWICH ISLANDS. [Myrtacem. 



infimum foliolorum par, stipulis subulatis, racemis axillaribus erectis folio brevioribus, legu- 

 mine pendulo lineari compresso membranaceo sub-8-spermo. 



This species seems to have been observed by Gaudichaud (Freyc. Voy. p. 94.) to whom we have dedicated 

 it ; but he says that the pods are narrow and short, which does not well apply to ours. The whole plant is 

 perfectly smooth; the leaves about six inches long, and the leaflets an inch and a half ; these last are 

 on short petioles, about a line in length : the lower pair only are provided with a slender filiform gland, 

 rather more than half a line long, which is incrassated and blunt, not acute at the apex as in C. oxyadena, to 

 which this species seems allied. The pod is about three lines broad, and 3-4 inches long, very compressed 

 and membranaceous, suddenly and shortly attenuated at both extremities. There are complete septa between 

 the seeds, which are flat and almost black.

We agree with Gaudichaud in referring the species found in Oahu to J. angustifolia. The leaves, how- 

 ever, are slightly petiolate, and the lobes of the calyx, although acute, are not remarkably so. Mr. Collie, 

 in his notes, remarks that the petals are obovate, rotundate, and emarginate ; their claws, internally, and the 

 bases of the stamens, are somewhat villous.

This we possess, from the same country, from Mr. Menzies, Mr. Macrae, and Chamisso.

These varieties, again, but particularly the first, occur either perfectly smooth or more or less tomentose. 

 Specimens of all of them are in the Collection, and we possess, in addition, several distinct forms of the 

 second variety, collected by Mr. Macrae. Var. /3. was found long ago by Mr. Menzies, but was probably 

 confounded by Smith with his M. villosa, to which it is indeed too closely allied, and perhaps only distinguish- 

 able by the pedicellate flowers. This appears, according to Gaudichaud's valuable observations, to be a most 

 variable plant. Nothing, says he, is more remarkable than the M. polymorpha, which is found with linear 

 leaves towards the summit of the mountain, but successively linear-lanceolate, lanceolate, ovate, obovate,
