cle. Fruit ovate-pyramidal, several usually ripening in the head, 

 closely sessile, 5" -7" long, 5-6-angled, pointed with a slender beak.

2. S. (SICYOCARYA) MACROPIIYLLUS Gray. (Enum. No. 143.) Stem 

 strongly angled, pubescent or quite glabrous. Leaves rounded-cor- 

 date, slightly or more deeply 3-5-lobed, often large, 3' -10' in diam- 

 eter, membranaceous, glabrous or softly puberulent underneath, not 

 scabrous, the margin sharply toothed with short callous-tipped teeth ; 

 petioles 3' long. Male panicles umbellate at the summit of a long and 

 slender peduncle (5' -7' long) glandular-puberulent as are the flower 

 buds, on pedicels 4"-5'"4ong, which are often fascicled. The peri- 

 anth becoming 5" in diameter when expanded. Female flowers clus- 

 tered at the summit of a short peduncle. Fruit ovate, 5-6-angled, 

 nearly glabrous, conspicuously beaked. 



Forests of Mauna Kea, Hawaii. 



3. S. (SICYOCARYA) CUCUMERINUS Gray. (Enum. No. 144.) Stem 

 strongly angled, glabrous. Leaves broadly cordate, or sometimes 

 almost kidney-shaped, undivided and scarcely lobed 3i'-6j' in diam- 

 eter, glabrous, membranaceous, the margin sharply denticulate. Male 

 flowers in a three-branched racemose panicle on a short or long (2'-4') 

 peduncle, the perianth 5-cleft to the middle, about 4" broad when ex- 

 panded. Female flowers on the summit of a shorter peduncle; the 

 ripe ovaries a few together at the summit of the peduncle, sessile, 

 oblong, an inch long, 5-6-angled but not sharply so, and with a long 

 beak which often breaks off. One variety presents leaves which are 

 slightly lobed, and another variety leaves which are palmately 3-lobed, 

 nearly to the base, the lobes being again more or less lobed, and all 

 sharply toothed, and sometimes scabrous.

 Waimea, Kauai. 



4. S. (SICYOCARYA) MICROCARPUS H. Mann. {Enum. No. 165.) 

 Stem strongly angled, glabrous. Leaves papillose-scabrous above, 

 hispid below, on slender petioles of more than their own length, l'-2i' 

 in diameter, angled, deeply cordate at the base, thin membranaceous. 

 Male panicles three-branched, on slender peduncles exceeding the 

 leaves in length, flowers very small. Female flowers 30-40 in a head 

 on a peduncle only 3" or 4" long; the fruits 2" long, sessile, and 

 crowded, several angled by mutual pressure, short-beafked.
