Page 1077, after Gerardia maritima, insert : 



12a. Gerardia spiciflora Engelm. Steins mostly 3-7 dm. tall, simple or much- 

 branched. Leaf -blades succulent, linear-spatulate to narrowly linear, 2-4 cm. long, 

 acute or acutish: pedicels somewhat club-shaped, 2-6 mm. long: calyx-tube campanu- 

 late, 2.5-3 mm. long, the lobes obtuse, but sometimes becoming acutish in age, much 

 shorter than the tube: corolla rose-purple or pink, about 1.5 cm. long: capsules 6-7 

 mm. in diameter. Differs from G. maritima in the larger flowers, the narrower calyx- 

 lobea and the pubescent filaments. 



In damp sandy soil along the coast, Florida to Louisiana. Also in the West Indies. 

 Spring to fall. 



Page 1079, after Castilleja purpurea, add: 



5. Castilleja sessiliflora Pursh. Perennial, cinereous-pubescent. Stems 1-2.5 

 dm. tall, often tufted: stem-leaves with narrow once or twice 3-5-cleft blades: bracts 

 nearly or quite similar to the leaves, green: calyx colored like the bracts: corolla 4-4.5 

 cm. long, yellowish or greenish-white. Differs from C. purpurea in unequally cleft 

 calyx, the larger corolla and the green calyx and bracts. 



In sandy soil, Wisconsin to Saskatchewan, Texas and New Mexico. Spring.

la. THUNBERGIA L. f. 



Perennial vines. Leaves opposite: blades sagittate or hastate. Flowers solitary, 

 or few together in cymes, often foliaceous bracted. Calyx persistent: lobes several, 

 narrow or obsolete. Corolla variously colored or white, the short tube dilated into a 

 throat, the limb with relatively large lobes. Stamens 4, didynamous: filaments thick- 

 ened at the base: anther-sacs parallel, sometimes slightly unequal. Capsules mostly 

 surrounded by the broad bracts, the short body abruptly narrowed into a flat beak. 

 Differs from our other genera of ACANTHACEAE in being composed of vines and in the 

 rounded abruptly flat-beaked capsule. 



1. Thunbergia fragrans Eoxb. Plant with twining branches: leaf -blades lance- 

 olate to ovate in outline, more or less prominently hastate, 4-11 cm. long, angularly 

 toothed on either side of the base, rather long-petioled : mature bracts deltoid to 

 triangular-lanceolate, 2-2.5 cm. long: calyx-lobes 12-16, about \ as long as the tube, 

 2-3 mm. long: corolla white; limb 3.5-4.5 cm. wide, the lobes truncate: capsules 2.5- 

 3.5 cm. long. 



In hammocks and waste places, peninsular Florida. Naturalized from the East Indies.

 about 1 mm. wide," read "limb about 1 cm. wide." 



Page 1084, after Euellia parviflora, insert : 



6a. Ruellia succulgnta Small. Foliage glabrous or nearly so. Stems 1.5-5 

 dm. tall: leaf -blades narrowly oblong to spatulate, 2.5-4.5 cm. long, purplish to green- 

 ish-purple: calyx ciliate; lobes linear-filiform, 13-16 mm. long: corolla purplish-blue, 

 45 cm. long: capsules oblong or nearly so, the stipe very short. Differs from R. 

 parviflora in the erect, succulent fistulose stems. 



In moist or wet soil, Everglades, Florida. All year.

FAMILY 17a. PEDALIACEAE Lindl. BENNE FAMILY. 



Herbs or rarely shrubs. Leaves opposite or sometimes partially alternate: 

 blades entire, toothed or lobed, usually petioled. Flowers perfect, in axillary or 

 terminal clusters. Calyx of 5 partially united unequal sepals. Corolla irregu- 

 lar: tube long or short, rarely spurred at the base: limb 2-lipped, the 5 lobes 

 usually broad. Androecium of 4 didynamous stamens and one staminodium. 

 Gynoecium of usually 2 united carpels. Style elong-ated. Stigmas 2, often 

 somewhat foliaceous. Fruit a capsule, unarmed or with simple or hooked 

 spines. Seeds wingless or winged.
