Aquifoliaceae-Celastraceae. 



sionally met with in the drier districts. It can be found usually in company 

 with Pcrrottetia sandicicensis (Olomea*), Cheirodendron Gaudichaudii (Olapa], 

 Straussia, Bobea, Elaeocarpus bifidus (Kalia), and others peculiar to that zone. 

 The tree is seldom tarnished by insects or blight, and the dark glossy leaves make 

 the tree a conspicuous object in the forest, and more so when it is in full bloom, 

 exhibiting its cymes of white flowers in the upper axils, and abundant small black 

 fruits below r the leaves, along the stem. 



The leaves vary tremendously in size, shape and texture, and so does the in- 

 florescence, which is sometimes very shortly peduncled and appears to be ter- 

 minal. A form with very small leaves is not uncommon on Kauai, while the 

 biggest fruited specimens the writer collected on the slopes of Mt. Hualalai, in 

 North Kona, Hawaii. 



The wood of the tree is whitish and rather soft. It has been employed for 

 saddle-trees by the Haw r aiians of today. 



CELASTRACEAE. 



With the exception of the Arctic Zone, the Celastraceae are to be found in all 

 floral regions, but especially in southern and tropical Africa, including Madagas- 

 car; also in tropical and subtropical Asia, in China, and Japan. 



The genus Perrottetia, which occurs in the Indo-Malayan region, is also to be 

 found in tropical America, with one species in the Hawaiian Islands. The family 

 consists of 38 genera with numerous species.

Flowers hermaphrodite or unisexual; calyx broad, flat cupshaped to obconical; lobes 

 triangular 5, short, erect, open or imbricate in the bud. Petals 5, erect, similar to the

 flowers longer than the petals, in the female flowers very short, sterile, filaments filiform 

 or subulate, anthers broad round or oval, versatile; ovary ovate, or lageniform, free from 

 the disc, mostly 2 celled or oftener apparently 4-celled at the base. Ovules 2 in each cell. 

 Style short, stigma 2 or 3 to 4 parted, 1 to 2 erect ovules in each cell. Fruit a thick fleshy 

 globose berry with persistent calyx, corolla, disc and stamens, 2 to 4 celled, cells 1 to 2 

 seeded. Seeds round with thin fleshy albumen. Unarmed trees or shrubs with alternate, 

 thin coriaceous serrate leaves; stipules triangular, small and deciduous. Inflorescence
