Oleaceae-Loganiaceae. 



Kauai are exceedingly large and oblong acuminate. It flowers usually in March 

 in certain localities, but the writer found the trees in South Kona on the lava 

 fields of Kapua loaded with the ripe bluish fruits during the month of January. 

 It is a graceful tree and reaches often a height of 60 feet, with a trunk of 3 feet 

 in diameter; the bark is thick and very corrugated, often divided into oblong 

 scales. It occurs on all the islands of the group, especially on the dry leesides 

 from 600 to 4000 feet elevation. On Kauai it grows in the great Waimea Canyon 

 and at Halemanu, as well as Milolii and in Kopiwai forest, where the writer met 

 with handsome specimens. The biggest tree the writer saw in the Kipuka Puaulu 

 on the edge of an old aa lava flow near the Volcano Kilauea, on the slopes of 

 Mauna Loa, elevation 4000 feet. 



The wood of the Pua is extremely hard, close grained and very durable; it is 

 of a dark brow r nish color with blackish streaks, exceedingly heavy and takes a 

 most excellent polish. The wood was often used by the natives for various pur- 

 poses such as adze-handles. In helping to shape the fish hooks, the Pua wood was 

 used, as well as the rough pahoehoe lava rock, as rasps. 



LOGANIACEAE. 



The family Loganiaceae, with its 31 genera and more than 370 species, is de- 

 cidedly tropical ; only few representatives are found outside the tropics, and 

 only two genera are found distributed in the tropics of the whole world, while 

 the remaining ones are restricted to certain regions. In the Hawaiian Islands 

 only one genus (Labordia) of this family occurs, which is endemic. 



LABORDIA Gaud. 



Flowers hermaphrodite or unisexual, pentamerous. Calycine lobes large, lanceolate 

 or foliaceous, occasionally unequal. Corolla distinctly tubular, with narrow, lanceolate 

 contorted lobes. Stamens with short filaments and enclosed linear anthers. Ovary 2 to 3 

 celled, with cylindrical style and elongate clavate stigma; ovules many. Fruit a capsule. 

 Seeds ovoid or ellipsoidal imbedded in an orange colored or greenish pulp; with fleshy 

 albumen. Embryo straight with short cotyledons and longer radicle. Small trees or 

 shrubs; stipules sheathing. Inflorescence a terminal cyme, corymbiform or paniculate, 

 sometimes reduced to a single flower. 



The genus Labordia consists of numerous species, and is endemic to the Ha- 

 waiian Islands. Only a few become trees, while the majority of them are 

 shrubs inhabiting the middle forest zone along stream beds or in swampy 

 grounds in dense shades up to an elevation of over 5000 feet. Only one or two 

 occur on the forehills of the dry districts at the outskirts of the forests, as for 

 example in Mahana Valley on Lanai. The native name of nearly all the species 

 is Kamal;aliala. The majority of the species have green flowers, while some have 

 orange colored thick fleshy corollas. 



H. Baillon in his treatise on the tribe of Labordia remarks that in his opinion 

 the Genus Labordia cannot be sustained. He goes on to say that owing to 

 the imbricate and more often twisted corolla the genus should rather be classi- 

 fied under the family Apocynaceae than Loganiaceae. "The existence of stipules
