Sapindaeeae. 



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

 as Pelea, Xaiithoxylum, Boliea, Pittosporum, Pterotropia. Tetraplasandra. etc. 

 Owing til 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 tonyh, has not been made use of liy the 

 natives, as far as can l)e ascertained. The briuht scaidet fruit fle.sh is eattm liy 

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

 to the taste. 



The Mahoc is endemic to the Hawaiian Islands, and is remarkal)le for its 

 fruits, which are the largest in the genus. 



The name Mnliof. meaning "twins," undoubtedly refers to the double fruits, 

 which are not uncommon in our Alectryon. 



DODONAEA.

 lirieate or ^■al\■ate; petals none. Disc de\'eloi'ed or in the feni. flowers forming a sliort 

 carpoi'liore. Stamens s or less, rarely more, with short fllameuts and elongate anthers. 

 Ovary nsually orhirnhir or oboordate, mostly 3- also 2- or 4, rarely .3-fi ridded with as many 

 cells as ridges and with 2 o"\"iiles in eaoh cell, the uppier ascending and apotropons. the 

 lower pendulous and epitropons, styles short, with 3 to li short stigmating loljes. Capsule 

 papery or i-oriaceous. 3-2-ti celled, winged, rarely without wings. Seeds single or 2 in 

 eacli cell, glohose or lentiform. Embryo s]iirallv twisted, containing aleurou as well as 

 sa]ionine. — Trees or shrulis often only bushes witli a viscous surface; leaves simple, or 

 pinnate (not in the Il.aw.aiian species), often covered with resinal glands. Floweis pedi- 

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



The genus Dodmuiea consists of 46 sjiei'ies, 44 of which are endemic in Aus- 

 tralia, including the cosmopolitan T). visvosn L., which can be found in all 

 tropical countries. 



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

 D. criocarjja Smith, and D. stciiopic ra Illid., the latter a shrub 2 to 4 feet high 

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

 there is only one other species, D. nxidfn/nscaiioisis 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 lyy the 

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