174 MANN, 



nerved. Cymes dichotomous, mauy-flowered. Seeds often persisting 

 on the torus after the pericarp has fallen oiT. 



Genus probably limited to one very variable species, ranging from Australia through- 

 out most of the Pacific. 



1. A. EXCELSA Beissek. {Enum. No. 87.) A tall hard-wooded 

 timber-tree, the young branches, petioles, and inflorescence hoary or 

 rusty with a close tomentum, sometimes nearly glabrous. Leaves 

 petiolate, varying from broadly ovate or almost orbicular and very 

 obtuse, to ovate or ovate-lanceolate and acute or acuminate, usually 

 3' -6' long, entire, coriaceous, glabrous or slightly hoary above, white 

 or rusty-colored beneath with a close tomentum, the parallel pinnate 

 veins very prominent. Flowers 2" - 3" in diameter, in little umbel- 

 like cymes, arranged in dichotomous cymes in the upper axils or in a 

 terminal corymbose panicle. Calyx tomentose, often very much so, 

 and rusty. Disk broad and nearly flat. Fruit 3"- 4" in diameter, or 

 sometimes larger. 



Mountains above Waimea, Kauai, where it attains a size of nearly 100 ft. high and 2 it. 

 in diameter at base. Maui, Lauai, and.probably Hawaii also. Perhaps on Waialua Moun- 

 tains, Oahu. A large and valuable timber-tree of which the natives manufacture their 

 kapa mallets, their spears, &c. Eanges through the Pacific into Australia. 



3. GOUAIiriA Jacq, 



Flowers polygamous. Calyx-tube short, cohering with the ovary, 

 5-lobed. Petals 5, inserted on the margin of the disk, hooded. Sta- 

 mens 5, included in the petals. Disk glabrous or pilose, filling the 

 calyx tube, 5-angled or produced into 5 horns. Ovary immersed, 3- 

 celled. Style 3-parted : stigmas minute. Fruit coriaceous, inferior, 

 being crowned by the persistent calyx, 3-winged : cocci somewhat 

 woody, indehiscent, and separating from the axis. Seeds plano-con- 

 vex, obovate, testa horny and shining; albumen scanty. Cotyledons 

 round. — Shrubs, often climbing and tendril bearing, glabrous or to- 

 mentose. Leaves alternate, petioled, entire or dentate, penninerved 

 or 3-nerved. Stipules oblong, deciduous. Flowers small, in terminal 

 or axillary spikes or racemes ; the rachis often transformed into a ten- 

 dril. 



A genus of 40 species, mostly in Central America and West Indies, a few African and 

 Asiatic, and a few in the Pacific, none in Australia. 



1. G. viTiFOLiA Gray. {Enum. No. 88.) A shrubby glabrous 

 plant, climbing by tendrils. Leaves membranaceous, about 2' long by 

 nearly as wide, glabrous, or with a soft pubescence beneath, crenate- 

 toothed. Flower-spikes short or about equalling the leaves in length, 

 dense, especially towards the upper part which bears the sterile
