spot, such was the nature of the vegetation that we could not rediscover the desired tree. It 

 was much more beautiful, and if not a distinct species, was yet a remarkable variety. 



P. campamMta is common in the locality mentioned, or between the ridge of Ualakaa and 

 the summit of Konahuanui in the thickly wooded depressions at middle height, and takes to 

 some extent the place of Melicope so common on other islands.

Stem simple, five to fifteen feet high, naked except at top. Leaf scars mostly obliterated 

 at the base where the circumference is often two feet. Leaves six to ten inches long, simple, 

 obovate, more or less cup-shaped, with a short fleshy petiole extending through the leaf as a 

 prominent midrib, collected in a sort of head at the summit of the stem, in color light, 

 vivid green. Peduncles stout and. fleshy, three to five inches long ; the thick ascending 

 pedicels half an inch or an inch long ; bracts deciduous. Calyx-teeth much shorter than the 

 tube, oblong-linear, slightly accrescent and persistent in the ripe fruit. Corolla showy, 

 slightly fragrant, white with a tinge of cream-color, greenish in bud ; the rather slender 

 tube four to six inches long, slightly incurved ; the five lobes when expanded about an inch 

 long, thickish, valvate in aestivation, and flat so as to give a pentagonal section to the bud ; 

 the pointed tips indexed, in size and position nearly equal and regular as in Isotoma. but the two 

 anterior lobes separated from each other and from the lateral ones by sinuses forming narrow 

 claws of nearly the same length as the lobe. The anther tube is half an inch long, scarcely 

 projecting beyond the cleft of the corolla, straight with the apex abruptly curved towards 

 the upper side of the flower, and tipped with a uniform tuft of beard, otherwise glabrous. 

 Stigma neither bearded nor indusiate, of two small and flat rounded lobes. Ovary acutely 

 and nearly equably ten-ribbed. Fruit capsular, three fourths of an inch long, fleshy-coriaceous, 

 ten-ribbed, green when ripe, with a purplish tinge at the base of the persistent calyx-teeth, 

 white inside ; each cell opening by two equi-distant, longitudinal, intercostal chinks or clefts 

 extending from just below the apex to the base. Seeds very numerous, half a line long. 

 Described by Dr. Gray from a specimen collected by Jules Remy, communicated by the 

 Paris Museum, and from specimens collected by William T. Brigham, Esq., including fruit 

 and flowers in alcohol. 



Dr. Gray remarks that the resemblance of this plant to Isotoma is mainly in the great 

 length and general form of the corolla, but its true relationship is evidently with the unfor-
