Loganiaceae. 



which has much narrower, lanceolate and longer petioled leaves, with less closer 

 internodes, is perhaps but another variety of L. fagraeoidea. Their inflor- 

 escences are contracted and pauciflorous, and the divisions of their corollas are 

 linear. ' ' 



In the writer's opinion the plant is quite distinct from Gaudichaud's L. 

 fagraeoidea. 



The species Labordia are certainly very badly confused, earlier authors, as 

 Mann, giving only three or four line descriptions which may be applied to sev- 

 eral variable species, have later been enlarged upon by other authors simply 

 taking for granted that their specimens are referable to either the one or the 

 other, increased the confusion rather than clearing matters up. Until type- 

 material of all the previous authors has been examined and compared, a satis- 

 factory treatise on this difficult genus cannot be undertaken. 



L. Molokaiana occurs on Molokai principally, where it was collected by the 

 writer at the pali of Wailua in the dense rain forest, at an elevation of 3000 

 feet. The specimens agree exactly with Hillebrand's description of L. lopho- 

 carpa, which is a synonym of the former (flowering and fruiting no. 7044, April 

 15, 1910). Hillebrand enumerates two varieties, pluriflora and phyllocalyx 

 which may be distinct species.

LABORDIA MEMBRANACEA Mann in Proc. Am. Acad. VII. (1867) 197. Wawra in 

 Flora (1872) 516; Hbd. Fl. Haw. Isl. (1888) 291; Solereder in Engl. et Prantl 

 Pflzfam. IV. 2 (1892) 32; Del Cast. 111. Fl. Ins. Mar. Pacif. VII. (1892) 237. 

 Branches thick, fleshy, pubescent with short dark brown hair, terete, or slightly 

 angled; leaves broadly ovate, shortly acuminate, (not membraneous when fresh) rather 

 fleshy, succulent, pale underneath, dark green and shining or somewhat dull above, petioles 

 thick fleshy, midrib thick, prominent, veins transparent; interpetiolar stipules very short, 

 rounded or truncate; inflorescence terminal, a three-flowered cyme, subsessile or sessile 

 in the axis of the uppermost leaflets, with two linear bracts at the base; peduncles terete 

 fleshy, alternately bracteolate, bracteole, linear subulate; calyx divided nearly to the 

 base into five linear acute segments 1.5 cm long, hirsute with blackish hairlets as is the 

 whole inflorescence; corolla pale yellow, the long slender tube urceolate, about 2 cm long, 

 the lobes (5) reflexed, about 2/3 the length of the tube, acuminate; anthers sessile at the 

 throat of the tube, between the sinuses of the corolla-lobes, slightly exserted; ovary two- 

 celled, oblong-conical, about 1 cm high, style short about 2 mm, stigma large, clavate 5 

 mm long, 2.5 mm thick, slightly notched or grooved at the apex. Capsule two-valved, very 

 large 40 mm long, 18 mm broad, conical-oblong, the valves not ridged at the back. 



Mann describes a small tree from the mountains behind Honolulu under La- 

 bordia membranacea, though very briefly. The writer found numerous trees 

 which will have to be referred to Mann's species. Like all Labordiae it is some- 

 what variable. It is however easily distinguished, by the large oblong leaves 

 and exceedingly large capsules. The writer has enlarged upon Mann's descrip- 

 tion. The flowers of this species are hermaphrodite. It occurs in the dense 

 rain forests of the main range of Oahu, especially between Manoa and Mt. 

 Olympus trail, where it is a small tree 10 to 18 feet in height.
