4. S. pachycarpus, Hook. d& Arn. in Bot. Beech. p. 83. — Stem 
a broad basal sinus, 3—5‘ long and as much or more in breadth, angular 
or obscurely 3—5-lobed, the lobes subequal, broad triangular and short, 
faintly denticulate, glabrous above or sparsely covered with white papillae 
(the bases of hairlets), rather hispid underneath (or papilloso-scabrous); 
the petioles 1—2'/2‘, Male fl. Panicle racemosely branching, with a peduncle 
of 1—5’. Perianth as in no. 3. Anthers 3—5, united into a globose head, 
their cells curved. Fem. fl. numerous, sessile in a head on a peduncle 
of 2—10". Calyx iia: pubescent, the tube ovoid, with a short bea 
which carries a small deeply cleft perianth only '/2—1” high. Ripe 
fruit 4 to 8, ovoid-pyramidal, 5—9“ long, including the pointed apex or 
beak, sharply trigonous, each face with a prominent midrib, smooth, 
amygdaloid, with rather thick cotyledons. — Gray, I. ¢. p. 650, pl. 80. —

Kauai! (Kn.). — The Maui specimen referred here by Gray, and M. & B.’s no 
the same island, belong to e 2, — ie my specimens are without fruit, the description 
of it is copied from Gray, his «testa» probably re to what I take to be the 
endocarp. It is somewhat doubtful, however, if Gray’s S. pachycarpus 1s the same as 
that of Hooker & naan for the latter authors assign a height of only 1'/2—2” to their 
fruit, which points to S. microcarpa. 
5. S. macro evita Gray, 1. c. p. 651, pl. 81. — Leaves on petioles 
of 3‘, large, 7—10’ in diameter, membranous, glabrous above, softly 
puberulous underneath, cordate, with a deep narrow basal sinus, 3—5-lobed, 
form pedicels often fascicled, 4—5“ long. Perianth greenish-white, large, 
5“ in diameter when eae the calyx teeth short subulate. Anthers 
slightly twisted. Fem. fl. Ripe fruit few and shaped as in no. 3, clustered 
on a peduncle of 2 
Hawaii in forests of Mauna Kea, toward their upper margin (U. S. E. E.).
