each other and from the lateral ones by sinuses, forming narrow claws 

 of nearly the same length as the lobe. The anther-tube half an inch 

 long, scarcely projecting beyond the cleft of the corolla, straight, with 

 the apex abruptly curved toward 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 10-ribbed. Fruit three fourths of 

 an inch long, fleshy-coriaceous, 10-ribbed, evidently capsular; each cell 

 opening by two equidistant, longitudinal, intercostal chinks or clefts 

 extending from just below the apex to the base. Seeds very numer- 

 ous, half a line long. — Described from a specimen in Remy's collec- 

 tion, communicated by the Paris Museum, and from flowers and fruits 

 collected by Mr. Brigham, and preserved in alcohol. — This very in- 

 teresting addition to the peculiar Lobeliacese of the Sandwich Islands, 

 I have dedicated to Mr. Mann's companion in Hawaiian exploration, 

 William T. Brigham, Esq., who not only, after M. Remy, discovered 

 it, and brought the materials needful to complete its characters, but 

 who has paid particular attention to this group of plants, collecting spec- 

 imens, and especially making sketches of the arborescent species he 

 met with. The fruit of my specimen from Remy would rather be 

 thought to be baccate; but Mr, Brigham's prove it to be capsular. 

 The resemblance of our plant to Isotoma is mainly in the great length 

 and general form of the corolla. But its true relationship is evidently 

 with the unfortunately little-known Sclerotheca arborea, A. DC. (Lobe- 

 lia arborea, Forst.) of Tahiti. In that, however, so far as is made out, 

 the corolla is no longer than the foliaceous calyx-lobes, and cleft to the 

 base, and the capsule opens at the vertex by two round pores. The one- 

 flowered peduncle is of small moment, as it is bibracteate ; and I sup- 

 pose it is not certain that the flower is resupinate after the manner of 

 the order, although so described by De Candolle. In the present plant 

 there is no torsion of the pedicel, and the odd sepal is anterior. Unless 

 future discoveries invalidate the characters, Brighamia and Sclerotheca 

 must surely be regarded as distinct, related genera." A. Gray, mss.

 Bot. Voy. Bonite, t. 46 ; Gray, 1. c. p, 150. A shrub with an upright 

 simple stem, 4 to 8 feet high, dividing at the top into a crown of flow- 

 ering branches, spreading like the arms of a chandelier. When the 

 light pink flowers have expanded, it is an exceedingly showy plant.
