between the leaves would be the only characteristic which might separate them 

 from the former family., had it not been demonstrated that too much value alto- 

 gether has been attached to the presence or absence of these organs, etc." 

 Owing to limited space it is here impossible fully to discuss this interesting ques- 

 tion. A definite settlement in regard to the nomenclature of our Hawaiian 

 Labordia will have to be deferred until the future. The writer possesses numerous 

 new species of Labordiae and complete material of those already known, which 

 will be worked up after the writer's return from Europe, where he will have 

 opportunity to compare his specimens with the typ>es in the various Herbaria of 

 Europe. Only after then can a satisfactory treatise on this difficult group be 

 published. 



KEY TO THE SPECIES. 

 Corolla yellow. 



Flowers single, enclosed within the foliaceous calyx lobes. 



Capsule small crested L. molokaiana 



Flowers several in a sessile cyme. 



Capsule 40 mm long, not crested L. membranacea 



Capsule 5 mm high, three valved, minutely pedunculate L. sessilis 



Corolla greenish. 



Flowers in a paniculate cyme L. tinif olia 



There are undoubtedly several more Labordia which become trees, but owing 

 to the general chaos in which this genus is at present, it was decided by the 

 writer -to limit the number of arborescent species to be described to four, as the 

 diagnosis of the latter is fairly certain. 



Labordia Molokaiana H. Baillon. 

 Kamakahala. 



LABOEDIA MOLOKAIANA H. Baillon in Bull. Soc. Linn. Paris, I. (1880) n. 30. 240; 

 Del Cast. 111. Fl. Ins. Mar. Pac. VII. (1892) 237. Labordia lophocarpa Hbd. PI. 

 Haw. Isl. (1888) 289; Solereder in Engl. et Prantl Pflzfam. IV. 2. (1892) 32. 



A tree 10 m high, glabrous, the younger branches fleshy, slender, and sharply ridged 

 or angular; stipular sheath large, emarginate laterally; leaves elliptical or obovate-oblong, 

 4 to 10.5 cm long, 2.5 to 3 cm wide, shortly acuminate, suddenly narrowing into a petiole 

 of 4 to 12 mm, thin chartaceous, dark underneath when dry, pale even whitish when fresh, 

 and somewhat fleshy in texture, glabrous or distantly hispidulous; inflorescence a single 

 terminal flower on a puberulous pedicel of 4 to 10 mm; bractlets lanceolate or spathulate, 

 12 mm; calyx as long as the corolla, the lobes 14 to 20 mm, divided into 4 to 5 broad 

 foliaceous sepals, shortly acuminate, 9 to 11 nerved; corolla deep yellow, enclosed in the 

 calyx, glabrous outside, puberulous inside, the broad tube 10 to 12 mm long; style 4 mm, 

 shorter than the broad clavate stigma; capsule 12 to 14 mm high, 2 to 3 valved, the 

 valves broadly winged at the back, above, with the wings rounded and generally not con- 

 fluent at the apex. 



In regard to the nomenclature of this species there seems to be some doubt 

 whether it is Hillebrand's Labordia lophocarpa or Gaudichaud's L. fagraeoidea, 

 but to the writer's mind it must be identical with the former. However, the 

 question cannot be decided definitely until material has been examined on which 

 Baillon based his description. Baillon states in regard to L. Molokaiana as 

 follows:* "The L. Molokaiana gathered on Molokai by Mr. J. Remy (no. 363)
