CORREA 



CORYDALIS 



long, usually bright scarlet, but also white or yellow. 

 Shrubs, usually with dense, minute, stellate hairs: Ivs. 

 opposite, stalked, entire, and with transparent dots. C. 

 speciosa is probably the best and most variable species. 

 It is a native of barren, sandy plains, and belongs to the 

 large and much-neglected class of Australian shrubs. 



559. Coronilla varia.

(See p. 379.) 



Specidsa, Ait. (C. cardindlis, F. Muell.). Tender 

 shrub, 2-3 ft. high: branches slender, brown, opposite, 

 covered with minute rusty hairs: Ivs. opposite, about 1 

 in. long, elliptic, about'a fourth as wide as long, wrinkled, 

 dark green above, whitish below, margin entire, re- 

 curved : peduncles opposite, axillary, longer than the 

 Ivs., 1-fld., with a pair of leafy bracts: fls. 1% in. long, 

 pendent, tubular, bright scarlet, with a very short limb 

 of 4 spreading, greenish yellow segments ; calyx small, 

 cup-shaped, with 4 almost obsolete teeth ; stamens 8, 

 exserted, about 34 in. B.M. 4912. There are several 

 varieties. -^ jyj > 



CORTADfiRIA. See Gynerium. 



CORTtTSA (named by the herbalist Matthiolus after 

 his friend Cortusus, professor of botany at Padua). 

 Prlmulacece. A genus of possibly 4 species of which 

 C. Matthioli, Linn., from the Swiss Alps, has long been a 

 choice and delicate but not very popular plant, suited 

 for shady parts of the rockery. It was long considered 

 the only species of the genus. It is an herbaceous 



perennial, about G in. high, pubescent, rhizomatous,. 

 with a few long-stalked, cordate, 7-9-lobed, dentate Ivs.,, 

 and a slender scape bearing an umbel of about 7 small, 

 rosy purple, drooping fls., which appear in summer. It 

 has some resemblance to Primula cortusioides. The 

 genus has possibly 4 species, and is distinguished from 

 Primula and Androsace by its stamens attached to the 

 base of the corolla, and its long-acuminate anthers. 

 According to J. B. Keller, its culture is similar to that 

 of the hardy Primulas, but it needs winter protection in 

 the northern states. 



CORYANTHES (Greek, korys, helmet, and anthos, 

 flower, referring to the shape of the lip). Orchiddcece, 

 tribe Vdndece. This complex genus, which is closely re- 

 lated to Stanhopea, is represented by several interesting 

 species inhabiting tropical America. Sepals spreading, 

 dilated, flexuose, conduplicate, lateral ones largest, dis- 

 tinct at the base : petals small, erect : labellum large, 

 tridentate, basal portion forming a hood, continued into 

 the column; distal portion bucket or pouch -like: column 

 pointing downwards, elongated, terete, bicornute at the 

 base, apex recurved : pollinia 2, compressed, caudicle 

 linear, arcuate. Pseudobulbous : Ivs. plicate, lanceo- 

 late, about 1 ft. long. The bucket part of the labellum 

 is provided with a spout-like structure, by means of 

 which the bucket overflows when about half full of a. 

 secretion which drops from a pair of glands near the 

 base of the column. The fls. of the species known are 

 not lasting, the sepals being of such delicate texture 

 that, though at first they fully expand, they soon collapse 

 and become unsightly. Although much interest attaches 

 to the species of Coryanthes, the genus is not generally 

 cultivated, since the fls. last too short a time and are 

 not particularly brilliant. For culture, see Stanhopea. 



macrantha, Hook. Ground color rich yellow dotted 

 with red. Hood and part of bucket brownish red : fls. 

 few, in drooping racemes. Caracas. P.M. 5:31. 



maculata, Hook. Sepals and petals dull, pale yellow, 

 bucket blotched on the inside with dull red. B.M. 3102. 

 Var. punctata has the petals and sepals bright yellow, 

 speckled with red, the hood yellow, blotched with red- 

 dish orange, the pouch pale, speckled and spotted with 

 red. Demerara. OAKES AMES. 



CORYDALIS (Greek, lark, the spur of the flower re- 

 sembling a lark's spur). Fumariacece. A large genus 

 of hardy plants allied to the Dutchman's Breeches, and 

 with finely cut foliage of a similar character, but weedier 

 and less delicate than the Dicentras. They are all of 

 easy culture. They prefer full sunlight but will grow in 

 half-shade. Prop, by division or seed. 



A. Fls. chiefly purple or rose, sometimes tipped yellow. 

 B. Plant perennial : root tuberous : stem -Ivs. few. 



bulbosa, DC. (C. s6lida, Sw.). Erect, 6 in. high : Ivs. 

 3-4, stalked, biternately cut, segments wedge-shaped or 

 oblong: root solid: fls. large, purplish. Spring. 



BB. Plant annual: root fibrous: stem-lvs. many. 



glauca, Pursh. Annual, 1-2 ft. high, very glaucous : 

 lobes of the Ivs. mostly spatulate : racemes short, pani- 

 cled at the naked summit of the branches : fls. barely 

 % in. long, rose or purple with yellow tips ; spur short 

 and round : capsule slender, linear; seeds with minute, 

 transverse wrinkles. Summer. Rocky or sterile ground, 

 Nova Scotia to Rocky Mts., and even Arctic coast, 

 south to Texas. B.M. 179. Not advertised for sale, but 

 probably worth cult. \ 



AA. Fls. chiefly yellow. ^ 



B. Plant perennial : root tuberous : stem-lvs. few. 



n6bilis, Pers. Perennial, erect : Ivs. bipinnately cut ; 

 segments wedge-shaped and lobed at the apex : fls. 

 white, tipped with yellow, and a dark purple spot; spur 

 1 in. long. Spring. Siberia. B.M. 1953, as Fumaria 

 nobilis. G.C. II. 19:725. 



BB. Plant annual or biennial : root fibrous : stem- 

 lvs. numerous. 



aurea, Willd. Annual, 6 in. high, commonly low and 

 spreading : fls. golden yellow, about % in: long, on 

 rather slender pedicels in a short raceme ; spur barely
