Sapindaceae. 



thrives in company with many other rare trees peculiar to that small area, such 

 as Pelea, Xanthoxylum, Bobea, Pittosporum, Pterotropia, Tetraplasandra, etc. 

 Owing to its scarcity, it is unknown to most of the old natives, who have heard 

 of it only in rare instances from their ancestors. 



The wood, which is very hard and tough, has not been made use of by the 

 natives, as far as can be ascertained. The bright scarlet fruit flesh is eaten by 

 the natives, as well as the kernel of the seed, and are not altogether unpleasant 

 to the taste. 



The Malioe is endemic to the Hawaiian Islands, and is remarkable for its 

 fruits, which are the largest in the genus. 



The name Malioe, meaning ' ' twins, ' ' undoubtedly refers to the double fruits, 

 which are not uncommon in our Alectryon. 



DODONAEA. 



Flowers dioecious, regular (often appearing as if hermaphrodite). Sepals 3 to 7 im- 

 bricate or valvate; petals none. Disc developed or in the fern, flowers forming a short 

 carpophore. Stamens 8 or less, rarely more, with short filaments and elongate anthers. 

 Ovary usually orbicular or obcordate, mostly 3- also 2- or 4, rarely 5-6 ridged with as many 

 cells as ridges and with 2 ovules in each cell, the upper ascending and apotropous, the 

 lower pendulous and epitropous, styles short, with 3 to 6 short stigmating lobes. Capsule 

 papery or coriaceous, 3-2-6 celled, winged, rarely without wings. Seeds single or 2 in 

 each cell, globose or lentiform. Embryo spirally twisted, containing aleuron as well as 

 saponine. Trees or shrubs often only bushes with a viscous surface; leaves simple, or 

 pinnate (not in the Hawaiian species), often covered with resinal glands. Flowers pedi- 

 celed, axillary or terminal, single, or in racemes or panicles. 



The genus Dodonaea consists of 46 species, 44 of which are endemic in Aus- 

 tralia, including the cosmopolitan D. viscosa L., which can be found in all 

 tropical countries. 



In Hawaii three species occur; the above-mentioned D. viscosa L., besides 

 D. eriocarpa Smith, and D. stenoptera Hbd., the latter a shrub 2 to 4 feet high 

 and peculiar to Molokai. Outside of the Australian and Hawaiian species, 

 there is only one other species, D. madagascariensis Rdlk.. which is peculiar to 

 Madagascar. They are trees or shrubs, or also bushes. 



The leaves in the Hawaiian Dodonaea or Aalii, as they are called by the 

 natives, are simple, usually covered with glands which secrete a resin.
