Family Tiliaceae. 



LOCAL NAMES. Masigsig lahe (Guam). 



Corchorus tomentosus, a plant of Japanese origin, was included in Gaudichaud's list 

 of Guam plants, but the name probably refers to Triumfetta tomentosa, or some allied 

 species of that genus. Corchorus differs from Triumfetta in having its fruit in the 

 form of a 2 to 5-celled capsule, the fruit of Triumfetta being indehiscent and spiny. 

 Flowers 1 to 3 together, small, yellow, opposite the leaves; sepals 5, distinct; petals 

 5, distinct; stamens numerous, distinct; ovary 2 to 5-celled, with numerous ovules; 

 capsule loculicidal, 2 to 5-valved, with numerous seeds. C. acutangulus, having the 

 capsule elongated, glabrous, strongly 3- winged and 6-angled, leaves ovate, rounded 

 at base, acute, serrate, the 2 lowest teeth often prolonged into filiform tails, is a wide- 

 spread tropical weed, found in the Solomon Islands and, possibly, in Guam. C. tor- 

 resianus, collected by Gaudichaud on Rota, the island next to Guam, is not further 

 known, and may prove to be identical with some other species.

A tree growing near the coast with large ovate leaves and orange or reddish 

 funnel-shaped flowers. Leaves alternate, petioled, 7.5 to 15 cm. long, obscurely 

 3-nerved, base rounded or subcordate, glabrous; flowers in short terminal and lateral 

 few-flowered corymbs, nearly glabrous, polygamous; hermaphrodite corymbs fewer- 

 flowered than the male; calyx 12.5 mm. long, 3 to 6-parted, the teeth short, triangu- 

 lar, villous within; corolla tube 1.5 cm. long, 5 to 7-lobed, one lobe external, the 

 lobes 15 mm. long, rounded; stamens usually 6; anthers shortly exserted; ovary 

 4-celled, glabrous; style terminal, long, 2-parted, its branches again 2-parted, linear- 

 spathulate; cells 1-ovuled; fruit an ellipsoid, acute, usually 1-seeded drupe, 2.5 cm. 

 long; seed coarsely muricate, subspinose. 



Not common in Guam, several trees growing near the village of Agat. In Hawaii 

 it is called "kou," etymologically the same as "tou" of Tahiti. The wood is rather 

 soft, but durable. It is much prized by the natives of Hawaii, who make of it cups 

 and poi calabashes, showing wavy bands of light and dark color when polished. The
