 roseum Rendlateri and G. argenteum carminatum Rend- 

 lateri. F.S. 20:2075. Not so well known as C. argentea.

CORTUSA (named by the herbalist Matthiolus after 

 his friend Cortusus, professor of botany at Padua). 

 Primulacese. Scapose, perennial, pubescent herbs with 

 long-stalked, cordate-ovate Ivs. and purple umbel- 

 late fls. C. Matthidli, Linn., from the Swiss Alps, 

 has long been a choice and delicate but not very popu- 

 lar plant, suited for shady parts of the rockery. It was 

 long considered the only species of the genus. It is an 

 herbaceous perennial, about 6 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 early spring. B.M. 987. L.B.C. 10: 956. 

 It has some resemblance to Primula cortusioidcs. 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. 

 Its culture is similar to that of the hardy primulas, 

 but it needs winter protection in the northern states. 

 Prop, by division of the roots. 



CORYANTHES (Greek, korys, helmet, and anthos, 

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

 Epiphytic orchids requiring warmhouse conditions. 



Pseudbulbous : Ivs. plicate, lanceolate: fls. in racemes; 

 sepals spreading, dilated, flexuose, conduplicate, lateral 

 ones largest, distinct at the base; petals small, erect; 

 lip large, tridentate, basal portion forming a hood, 

 continued into the column; distal portion bucket- or 

 pouch-like; column pointing downward, elongated, 

 terete, bicornute at the base, apex recurved; pollinia 

 2, compressed, caudicle linear, arcuate. The bucket 

 part of the lip 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 although 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 cult., since the fls. last too short a 

 time and are not particularly brilliant. This complex 

 genus, which is closely related to Stanhopea, is repre- 

 sented by several interesting species inhabiting Trop. 

 Amer. For cult, see Stanhopea. 



macrantha, Hook. Fls. few, in drooping racemes; 

 ground-color rich yellow dotted with red; hood and 

 part of bucket brownish red. Caracas. P.M. 5:31. 

 B.R. 1841. B.M. 7692. G.C. III. 28:355. O.K. 3:41. 



maculata, Hook. Fls. in a drooping raceme; sepals 

 and petals dull, pale yellow, bucket blotched on the 

 inside with dull red. B.M. 3102; 3747. B.R. 1793. F.S. 

 8:755 (as C. AVbertinx). A.F. 30:325. C.O. 1. Var. 

 punctata, Hort., 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. C. Cobbii is an unspotted form of this. 



C. Balfouriana, Hort. Similar in habit to a stanhopea, with 

 a long pendulous scape bearing 2 or 3 large and curiously shaped 

 fls. Peru. -C. leucocdrys, Rolfe. Sepals yellowish green, marked 

 with brownish purple, the petals white, marked with light purple, 

 the lip white with the bucket marbled with light rosy purple. 

 Peru. Lind. 7:293. C. Master siana, Lehm. Raceme erect; fls. 2 

 or 3, yellowish, tinged and spotted with copper-red. Colombia. 

 G.C. III. 29:19. C. Sdnderi, Hort. A very large-fld. plant 

 allied to C. macrantha, C. specidsa, Hook. Raceme of 2 or 3 fls.; 

 sepals and petals pale yellow; lip brown-red, the stalk brownish 

 yellow. Brazil. G.C. III. 36:106. B.M. 2755 (asGongora). C.O. 2. 



GEORGE V. NASH.f 

 COR^DALIS (Greek, lark, the spur of the flower 



resembling a lark's spur). Fumaridcese. Hardy plants 



allied to the Dutchman's breeches. 



Erect or prostrate herbs, usually perennially rooted, 



but often annuals: Ivs. lobed and finely dissected in 

 nearly all the species: fls. racemose, often yellow, less 

 frequently blue, purple or rose; petals 4, spurred as in 

 the Dutchman's breeches; stamens 6, hi 2 groups. 

 Ninety species, natives of the north temperate regions. 

 They are all of easy cult. They prefer full sunlight but 

 will grow in half-shade. Prop, by division or seed.
