400 DIADELPHIA HEXANDRIA 



the principal divisions disunion slender petioles, the midrib or common petiole 

 twining like a tendril, and supporting the plant ; segments one third to 3 fourths 

 of an inch Ion?, and 1 fourth to half an inch wide, obliquely ovate, or cuneate- 

 obovate, incised, or entire, subpetlolate. Racemes axillary, compound, 3 or 4 to 

 10 or 12-flowered, branches trifid, the common peduncle mostly arising from, or 

 adnate to, the base of the petiole ; pedicels a)x>ut half an inch long, with minute 

 bracts at base, thickened atapox. Se/xils small, lance-ovate, acuminate, striate, 

 produced at base. Corolla pale violet-purple, OM half to 2 thirds of an inch long, 

 compressed, lance-oblong, subcordate at base, contracted at throat, of a cellular 

 spongy texture, persistent, and becoming a dirty white. Capsule about half an 

 i nch long, 1 to6-seedei!, sheathed by the persistent corolla. Seeds subrenifcrm- 

 globose, slightly compressed, smooth, shining black. 



Hab. Banks of the Brandy wine; Coalesville: rare. Fl. July-Aug. *\. Aug-Sept. 

 Obs. Collected by Mr. Joshua Hoopes, in 183T>. It is the only species of the 

 genus ; and is often cultivated as an ornamental climber, upon arbors, dec. 



331- CORYDALIS. Vent. jXntt. Gen. 587. 

 [An ancient Greek name for the fumitory ; from which it has been separated] 



Sepals 2, membranaceous, minute, deciduous. Petah 4, somewhat 

 cohering, the upper one produced into a spur at base. Capsule sili- 

 quose, linear-oblong, mostly acuminate with the persistent style, 2-val- 

 ved, many-seeded. 



Herbaceous: caulescent; leaves mostly alternate, multifid ; flowers racemose, 

 terminal, and opposite the leaves. Nat. Ord. 10. Limit. Fumariace.«. 



1, C. aurea, mild. Stem branched, diffuse ; leaves glaucous, pin- 

 nately divided, divisions incised-pinnatitid, segments linear-oblong, 

 acute ; bracts oval-lanceolate, acuminate, subdenticulate, mostly longer 

 than the pedicels ; siliques terete, torulose. Seek, But. />. 24. 



Golden Coryualis. 



Plant smooth. Root annual ? Stem 2 or 3 to 6 or 8 inches high, striatc-angled, 

 often diffusely branching from the base. Leaves petiolate, 3 to B-parted; divis- 

 ions petiolale, pinnalifidly incised ; segments often bifid, the terminal ones trifid ; 

 ratlual or lower leaves mostly numerous, on long petioles. Racemes mostly op- 

 posite the leaves ; pedicels 1 third to 3 thirds of an inch long ; bracts rather large, 

 at first longer, finally often shorter, than the pedicels. Sepals very minute, lance- 

 linear or subulate (orbicular, DC.) } slightly produced at base. Corolla bright yel- 

 low, somewhat ringent,— the upper petal produced at base Into a short obtuse 

 slightly incurved spur; the border or summit of the upper and lower petals dila- 

 lated, ovate, dentate, crested on the back— that of the upper petal diverging, with 

 the margins reflexed. 

 Hab. Bank of the Schuylkill, at Black Rock: rare. Fl. May. Fr. June. 



Obs. This pretty little plant was found crowing on a rock, in the above locality, 

 by Miss Martha Kimbbr, in 1835. It is very rare,— and the specimens are small 

 (2 to 4 inches high) : under culture, in gardens, it becomes much stouter. One or 

 two additional species are enumerated in the U. States. 



332. FUMARIA. L. J\ntt. Gen. 588. 

 [Latin, Fumus, smoke ; perhaps in allusion to its glaucous hue.] 



Sepals 2, deciduous. Petals 4, the lower one linear, free, the others 

 cohering at base, the upper one produced into a spur at base. Capsule
