LAUEACEAE. 75 



1. C. Camphora (L.) Karst. Small tree or shrub: leaf-blades elliptic to 

 ovate, 4-12 cm. long, short-acuminate, pale beneath, long-petioled : panicles 

 slender-peduncled : sepals 1-1.5 mm. long: drupes globose to oval-globose, 6-9 

 mm. in diameter. — Spr. & sum. 



The Camphor-tree, a native of China and Japan, grows in woods and thickets 

 in peninsular Florida. The brown heart-wood is coarse-grained, light, and weak. 

 (W. I.) 



2. TAMALA Eaf. Shrubs or trees. Leaves alternate, persistent: blades 



entire. Elowers in axillary peduncled cymes. Sepals 6, dissimilar. Style 



long-columnar: stigma capitate. Drupe equilateral. — Spr. 



Peduncles, pedicels and petioles glabrous or appressed-pubescent : fruit over 1 cm. 

 thick. 

 Leaf-blades glabrous or nearly so, except sometimes the nerves 

 beneath. 

 Leaf-blades finely reticulated beneath, mainly over thrice 



as long as wide. 1. T. Borbonia. 



Leaf-blades not reticulated beneath, mainly about twice as 



long as wide. 2. T. littoraUs. 



Leaf-blades lustrous-pubescent beneath. 3. T. humilis. 



Peduncles, pedicels and petioles tomentose : fruit less than 1 cm. 



thick. 4. T. piiiescens. 



1. T. Borbonia (L.) Small. Large tree, the bark broken into flat ridges: leaf- 

 blades elliptic or elliptic-oblong, 5-15 cm. long, often acuminate at both ends, 

 bright-green and lustrous above, glaucescent and finely reticulate beneath: 

 sepals ascending, the inner ovate, 2-3 times longer than the outer, acutish: 

 fruit obovoid or globose-obovoid, 1-1.5 cm. long, dark-blue or nearly black, 

 lustrous. [Laurus Borionia L. Persea Bordonia (L.) Sarg.] 



The Red-bay grows in swamps and low hammocks nearly throughout peninsular 

 Florida. The red heart-wood is close-grained, heavy, and strong, but brittle. Also 

 known as Sweet-bay and Florida-mahogany. (Cont.) 



2. T. littoralis Small. Tree or shrub: leaf-blades elliptic or oblong-elliptic, 

 2-5.5 cm. long, mostly obtuse at the apex, bright-green and lustrous above, 

 pale and glabrous beneath, not reticulate, the lateral veins inconspicuous: 

 fruits globular, 12-14 mm. long, purple-black under the bloom. [Persea 

 littoralis Small.] 



The SiiORE-BAY grows in coastal hammocks along the lower two-thirds of the 

 eastern coast. The wood has not yet been studied. (Endemic.) 



3. T. humilis (Nash) Small. Small tree or shrub, the twigs, lower leaf- 

 surfaces and the inflorescence silky-pubescent: leaf -blades elliptic or oblong, 

 4-10 cm. long, more or less revolute, glabrous and shining above, lustrous 

 beneath: sepals erect, obtuse, the inner oblong, 5 mm. long: fruits globular, 

 about 1.5 cm. long, purplish-black under the bloom. [Persea humilis Nash.] 



The SiLK-BAY grows in scrublands in central peninsular Florida. The wood 

 has not yet been studied. {Endemic.) 



4. T. pubescens (Pursh) Small. Shrub or small tree, the twigs, lower leaf- 

 surfaces and inflorescence tomentose : leaf -blades narrowly elliptic or elliptic- 

 lanceolate, or rarely oval, 5-20 cm. long, usually obtuse, often acuminate at 

 the apex, slightly revolute: sepals erect, acutish, the inner oblong-obovate, 

 about twice as long as the outer: fruits oval, 8-11 mm. long, dark-blue with a 

 thin bloom. [Persea puhcscens (Pursh) Sarg.] 



The SwAMP-BAY grows in hammocks or swamps nearly throughout Florida. 

 The orange and brown-streaked heart-wood is close-grained," heavy, and soft, but 

 strong. Also known as Swamp red-bay. (Cont., Bah.) 



3. PERSEA [Plum.] Gaertn. Trees. Leaves alternate, persistent : blades 

 entire. Flowers in terminal panicled cymes. Sepals 6, similar, united at the 

 base. Style subulate: stigma minute. Drupe inequilateral. 



1. P. Persea (L.) Cockerell. Tree with wide-spreading branches: leaf -blades 

 elliptic or oval or nearly so, 8-15 cm. long, short-petioled (relatively small and
