1328 APPENDIX 



at the base: pedicels slender, 2-4 cm. long, short, hairy: sepals oblong to oblong- 

 lanceolate, 6-8 mm. long, obtuse: corolla pale blue, mostly 2 cm. wide. — Differs from 

 T. 'brevicaulis in the short-pubescence, the broad-based bracts and the smaller calyx. 

 In sandy soil, eastern Texas. Spring. 



Page 241, after Treleasea, insert: 



5a. ZEBRINA Schnizl. 

 Herbs with diffusely branching stems. Leaf-blades relatively broad. Cymes 

 borne in involucres of leaf-like bracts with saccate bases. Corolla-lobes essentially 

 equal. Stamens 6. Capsule stalked. — Differs from Treleasea in the united sepals 

 and petals. 



1. Zebrina p6ndula Schnizl. Stem and branches very weak: leaf -blades ovate 

 to elliptic-ovate, 3-8 cm. long, often mottled: calyx coralloid; lobes lanceolate: 

 corolla rose-purple or white; lobes ovate or suborbicular, 5-8 mm. long: capsules 

 ovate-oblong. 



In hammocks and waste places, peninsular Florida. Naturalized from tropical America. 

 Summer and fall. Wandering Jew. 



5b. ANEILEMA R. Br. 



Herbs with diffuse, often creeping stems and branches. Leaf-blades long and 

 narrow. Cymes subtended by involucres of leaf-like bracts. Perianth regular. 

 Stamens 3, or rarely 2. Capsules not borne in a spathe. — Differs from Commelina 

 in the inflorescence which is not subtended by specialized bracts. 



1. Aneilema nudiflorum K. Br. Plants 1-3 dm. tall, the stems often branched: 

 leaf -blades linear to linear-acuminate, 3-11 cm. long, ciliate at the base: cymes long- 

 peduncled: petals blue or purplish, 5-8 mm. long: capsules oval or globular, 4-5 mm. 

 long, minutely beaked. 



In sandy soil, southern Georgia and Florida. Naturalized from the East Indies. 



Page 244, after Eeteranthera reniformis, add: 



4. Heteranthera pedunculiris Benth. Stems creeping in the mud and rooting 

 at the nodes, or floating, 1 m. long or less, or sometimes longer, much branched: 

 leaves erect; petioles elongated; blades ovate to orbicular-ovate, 2-5 cm. long, entire, 

 cordate at the base: spathe several-flowered: perianth blue; tube straight or nearly 

 so, about 1 cm. long; lobes much shorter than the tube: anthers various, the 2 upper 

 oval, the lower one oblong and on an elongated filament. — Differs from H. reniformis 

 in the narrower leaf -blades, the exserted flowers and the blue perianth. 



In ponds, Missouri and Kansas to Mexico. Summer. 



Page 244, after Piaropus crassipes, add: 



la. Piaropus paniculkta (Spreng.) Small. Plants 3-6 dm. tall: leaves erect; blades 

 ovate, 7-11 cm. long: panicle 1-1.5 cm. long, many-flowered: peduncles relatively 

 slender: perianth mainly blue or purplish: calyx-lobes oblong 9-11 mm. long: 

 corolla-lobes obovate, slightly longer than and about twice as wide as the calyx-lobes, 

 the narrower one pale and with 2 yellow blotches below the middle. [Po7itederia 

 paniculata Spreng.] — Differs from P. crassipes in the ovate leaf -blades, the numerous 

 loosely paniculate flowers and the small perianth. 



In ditches, peninsular Florida. Naturalized from Brazil. All year. 



Page 246, after Tillandsia Valensuelana, insert : 



6a. Tillandsia subl^xa Baker. Plants similar to those of T. Valenzuelana, but 

 smaller throughout, and with an unbranched spike : sepals oblong, acute, 12-14 mm. 

 long: petals twice as long as the sepals: capsules less than twice as long as the sepals. 

 — Differs from T. Valenzuelana in the simple inflorescence. 



In hammocks, southern peninsular Florida. 



Page 247, in place of Catopsis Berteroniana, insert: 



Petals longer than the sepals: capsules fully twice as long as the sepals. 1. C. nutans. 



Petals shorter than the sepals: capsules slightly longer than the sepals. 2. C. Berteroniana. 



1. Catopsis nil tans (Sw.) Griseb. Blades of the basal leaves rather abruptly 

 narrowed into long slender tips, thus long-attenuate, and pliable: inflorescence lax: 

 bracts 4-5 mm. long: sepals 5-6 mm. long: capsules 11-13 mm. long, attenuate. 



In hammocks, southern peninsular Florida. Also in the West Indies.
