2. MARANTA L. 



Caulescent herbs, with branching stems. Leaves alternate : blades commonly of an 

 ovate or a lanceolate type, often abruptly bent at the base : petioles partly sheathing. 

 Flowers solitary or few in panicles. Perianth double : sepals 3, herbaceous, equal, distinct * 

 corolla often white, the 3 petals partially united. Staminodia conspicuous, 2 of them sur- 

 passing the corolla. Anthers 1-celled. Ovary 1-celled but with 2 additional abortive cavi- 

 ties. Style stout, curved. Stigma oblique. Capsule utricle-like. Seed erect, solitary. 



1. Maranta arundinacea L. Stems 1-2 m. tall, from starchy copiously scaly root- 

 stocks, more or less branched and rather weak, sometimes reclining, zigzag : leaf-blades 

 lanceolate to ovate-lanceolate, 8-25 cm. long, acute, many-veined : flowers few, fugacious : 

 sepals green, lanceolate or linear-lanceolate, 10-12 mm. long: corolla white, about 2 cm. 

 long ; lobes lanceolate : starninodia flabellate-cuneate, surpassing the corolla, erose, notched : 

 capsules broadly oblong, commonly 1 cm. long. 



In moist soil and damp hammocks, southern peninsular Florida. Introduced from tropical America. 



Page 351, under Quercus Catesbaei; the cup of the acorn is sometimes nearly or quite 

 turbinate. In the key, this species should also be contrasted with Q. Texana and ($. coccinea. 



Page 351, after Quercus coccinea insert : 



15a. Quercus borealis Michx. f. A large tree, commonly 20 m. tall. Leaves similar 

 to those of Q. rubra; blades 7-13-lobed to the middle or beyond it, somewhat lustrous and 

 deep green above, dull, paler and glabrous or nearly so beneath : acorn resembling that of 

 Q. coccinea, about \ as large as that of Q. rubra, short-peduncled ; cup turbinate, its scales 

 appressed ; nut ovoid, commonly about 2 cm. long, between twice or thrice as long as the 

 cup. 



In woods and on open slopes, Quebec and Ontario to the mountains of North Carolina. GRAY OAK. 



Page 403, at bottom of page insert : 



2. Rivina laevis L. Similar to JR. humilis in habit, but with glabrous foliage, and 

 commonly with smaller flowers and fruit ; it may be specifically distinct. It occurs in the 

 Gulf States and tropical America.

FAMILY 6a. BASELLACEAE Moq. MADEIRA-VINE FAMILY. 



Somewhat succulent vines, with tuber-bearing rootstocks. Leaves alternate : 

 blades relatively broad, often cordate, entire. Flowers perfect in spike-like 

 racemes. Calyx of 2 sepals, sometimes winged in fruit. Corolla of 5 often 

 somewhat colored petals. Androecium of 5 stamens borne opposite the petals. 

 Filaments terete or flattened, sometimes united below. Gynoeciurn 3-carpellary. 

 Ovary superior, 1-celled. Styles 3, distinct. Stigmas entire or cleft. Ovule 

 solitary, campylotropous, erect. Fruit utricular. Seed with a membranous 

 testa. 



Sepals oblong, shorter than the petals, wingless : stigmas cleft. 1. BOUSSINGAULTIA. 



Sepals boat-shaped, as long as the petals, broadly winged on the back at maturity : 



stigmas entire. 2. ANREDERA. 



1. BOUSSINGAULTIA H.B.K. 



Vines, with much-branched stems. Leaf-blades of an ovate type, rather fleshy. 

 Flowers in axillary and terminal spike-like racemes. Sepals 2, nearly flat, not winged, 

 Petals 5, longer than the sepals. Filaments terete, somewhat enlarged, but not dilated, at 

 the base. Stigmas cleft. 



1. Boussingaultia baselloides H.B.K. A glabrous vine climbing over other 

 plants. Stem much branched : leaf-blades ovate, 2.5-6 cm. long, acute, entire, abruptly
