and united into an elongate trigonous style, which has a nearly common puncti- 

 form stigma. Ovules solitary in the carpels, basilar, erect, anatrope. Fniit 

 always produced from the development of one carpel only, globular or ovoid, 

 regular, or very slightly asymmetrical at the base, and having the remnants of the 

 sterile carpels and the style at apex. The whole pericarp is generally not very 

 thick; the epicarp has a smooth surface; the mesoscarp is slightly fleshy or 

 grumous, or else more or less traversed by longitudinal fibres ; endocarp woody, 

 equally thin all around, but frequently thickened at the base, sometimes easily 

 separating from the mesoscarp at complete maturity. Seed globular, erect, and 

 free in the endocarpel cavity; hilum basilar raphe obscure or slightly impressed, 

 occupying a whole side of the seed, w'ith very few faint, or wholly obsolete 

 vascular branches ; the integument slightly more thickened on the raphe side than 

 elsewhere, but not penetrating into the substance of the albumen ; albumen homo- 

 geneous; embryo basilar, placed near the hilum, or else shifted toward the middle 

 of the antiraphe side. 



Fruiting perianth persistent, hardened, not, or very slightly, accrescent, 

 more or less pedicelliform. 



Conspectus of the Species.* 



I. Flowers exsuccous or coriaceous. (Palynesian species.) 

 A. Floriferous branchlets glabrous. 



a. Fruit globous, small (7 to 14 mm. in diameter). 



/). Leaf-blade green underneath and dotted there with small elliptical, 

 superficial lepidia. Spadices shorter than the leaves. Unopened flowers 

 7 to 7.5 mm. long. Fruit 12 mm. in diameter; pericarp 1.3 mm. thick 

 I. Pritchardia pacifica Seem, et Wendl. — Fiji. 



b.^ Flowers smaller than in the type. Fruit with a thicker i)ericarp . . 

 Pr. pacifica var. samoensis Becc, cultivated in Samoa. 



h.^ Leaf-blade waxy-glaucescent beneath, and dotted there with small 

 elliptical lepidia, which nest in depressions of the epidermis. Spadices 

 longer than the leaves. Unopened flowers 5 to 5.5 mm. long. Fruit 



7 mm. in diameter 



2. Pritchardia Thi'rstonii F. Muell. et Drude. — Fiji. 



b.^ Leaf-blade very obsoletely waxy-giaucescent beneath and dotted there 

 not closely with small elliptical, brown lepidia. Unopened flowers 10 to 

 II mm. long; the calyx 3 mm. long; the corolla three times as long as the 

 calyx. Floriferous branchlets relatively thick (4 to 5 mm. in diameter). 



Fruit 12 to 14 mm. in diameter 



3. Pritchardia Maiden iana Becc. The precise local- 

 ity unknown. Probably from some of the lower Polynesian Islands. 



* This conspectus was arranged by Doctor Beccari ; Professor Rock is, however, responsible for the 

 keys to the following species: No. ii, Pi: kcialae; No. 14, Pro. Forbcsiaiia ; No. 19, Pr. Hardyi; No. 20, 

 Pr. Muiiroi; No. 22, Pr. montis-kca; and No. 23, Pr. viscosa.
