 Flowering specimens of Alectryon macrococcus which until now were unknown, were collected by me, together with young and mature fruits on the southern slope of Mt. Haleakala, Maui, on the lava field of Auahi at an elevation of 2,600 feet, where the tree is not uncommon (see Report of the Board of Agriculture and Forestry for the Biennial Period 1910, p. 81).

Following is a description of the flowers of A. macrococcus with additional notes on the fruits:

Inflorescentia paniculata, contracta, axillaris, pilis flavescentibus prorsus induta; flores parvi, in pedicellos 2 mm longos, conferti; calyx 5-lobus 2 mm longus, lobis subacutis, persistens in coccis junioribus; petala nulla; stamina 6-8, inter sinus disci parvi extus inserta, filamentis brevissimis, hirsutis; antherae rubrae, 1 mm longae, ad basin subdidymae; ovarium a lateribus compressum, dense strigosum, 1-2-cellulis; stylus brevis, fere arctiatus, stigmate 2-fido; fructus 1-2-cocci, juniores pilis fulvis setulosis appressis, cum residuis styli, maturi glabri, fuscati, globosi, 3-6 cm diametro, arillo coccineo, etc.

Inflorescence an axillary contracted panicle, covered throughout with yellowish hairs; flowers small, on pedicells of 2 mm, densely clustered; calyx persistent with the young fruits, 5-lobed 2 mm long, the lobes subacute; petals none; stamens 6-8 inserted externally between the sinuses of the small disc, on very short hirsute filaments, anthers red, 1 mm long, subdidymous at the base; ovary compressed, densely strigose, 1-2 celled; style short almost arcuate, stigma two lobed; fruit consisting of 1-2-cocci, the young ones covered with appressed setulose, yellowish hairs, crowned by the remnants of the style, mature ones glabrous, dark brown, globose, 3-6 cm in diameter. Arillus scarlet, edible, etc.

Flowering and fruiting specimens (No. 8642) collected November 10-20, 1910. The wood is yellowish brown, hard grained and exceedingly tough. The flowers appear to be polygamous, as stamina are present in female flowers.
