Hepaticae. Liverworts. 



The liverworts of Guam have never been systematically collected. Among those 

 hitherto recorded from the island are Hygrolejeunea sordida ( Nees ) Schiff n. , growing 

 on damp tree trunks, Caudolejeunea recurvistipula (Gottsche) Schiffn., and Frullania 

 gaudichaudii Nees & Mart., belonging to the Jungermanniaceae.« Frullania nodulo&a 

 (R. Bl. & N.) Nees & was collected by the writer. It is a widely distributed species 

 in the eastern Tropics. 



Heritiera littoralis. Looking-glass tree. Plate lii. 



Family Sterculiaceae. 



Local names. — Ufa, Hufa(Guam); Chaiping, Chaping (Ponape); Pipilusu (Sol- 

 omon Islands); Looking-glass tree (India). 

 A tree growing near the sea, especially in the vicinity of mangrove swamps. Leaves 

 very shortly petiolate, oval or oblong, the larger ones 20 by 10 cm., but often much 

 smaller, entire, feather-veined, coriaceous, glabrous above, silvery underneath with 

 a close scaly tomentum; flowers small, numerous, unisexual, in loose tomentose, 

 panicles in the upper axils much shorter than the leaves; calyx 5-toothed or 5-cleft, 

 about 4 mm. long; petals none; in the male flowers staminal column slender, bearing 

 on the outside below the summit a ring of 5 anthers with parallel cells, shorter than 

 the calyx; in the female flowers, carpels of the ovary 5, nearly distinct, 1-ovuled; 

 style short, with 5 rather thick stigmas; fruit carpels sessile, ovoid, 5 to 7.5 cm. 

 long, thick, and almost woody, with a slight projecting inner edge, and a strong, 

 projecting, almost winged keel along the outer edge; seeds without albumen, 

 cotyledons very thick, the radicle next the hilum. 



The wood is durable, hard, and tough. In Guam it is used for spokes of wheels, 

 knees of boats, and especially for plows. The seeds of this tree were among those 

 collected by Doctor Guppy in the drift on the beach of some of the islands of the 

 Solomon group, evidently transported by ocean currents from other shores. The 

 East Indian name, "looking-glass tree," comes from the silver-like appearance of the 

 lower surface of the leaves.
