CORREA 



CORYDALIS 



long, iisually 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.

 his friend Cortusus, professor of botany at Padua). 

 Priinit/tlrcfr. A t^enus of possibly 4 species of which 

 ('. M:illhh,ti, Linn., fr..ni tin- Swiss Alps, has long been a 

 cli.iice and drli.-at.' but nut very popular plant, suited 

 for shady parts of tin- rock.-ry. 'it was long considered

 According to ,1. B. Keller, its culture is similar to that 

 of the hardy Primulas, but it needs winter protection in 

 the northern states.

 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, eaudicle 

 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 unsii,'litly. Although much interest attaches 

 to the species of roi-yanthes, the genus is not generally 

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

 not particularly brilliant. For culture, see Stanhopen.

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

 sembling a lark's spur). J^timariAeefB. 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.
