Hydroleacea.-] MEXICO.— SUPPLEMENT. 439 



Hab. 0. Between San Bias and Tepic, — Well preserved specimens of this plant have satisfied us that we 

 have confounded two very distinct species of Erythrma at our p. 302 above quoted. The Talisco plant is, 

 we believe, E. Texensis, Grisebach, Gent. p. 139. (E. Mexicana—Griseb. mst. in Herb. Hook.) in an 

 old state. The other is a broad leaved state of our E. macrantha. Dr Sinclair's perfect specimens have 

 the flowers so large that we did not hesitate, at first, in considering them as belonging to a large flowered 

 species of Chironia, particularly near some of the slender varieties of C. linoides i and the generic differ- 

 ences between the two, it must be acknowledged, are very slight. In our plant there is no perceptible connec- 



tivum between the cells of the anthers, which is the main character of Grisebach's Erythraacea : and the 



tube of the corolla is as short in our present species as in any Chironia. 



I. Halenia muliifiora (Benth. PL Hartweg. p. 24.); caule erecto folioso angulis suba- 

 latis, foliis trinerviis ellipticis lanceolatisve obtusissimis obovatis in petiolum angustatis, 

 cymis umbellaeformibus, sepalis lanceolatis acutis, calcaribus crassis corolla quadrifida 

 quadruplo brevioribus. Benth. 



Hab. Between San Bias and Tepic. — This has the shortest spurs to the corolla of any species we are 

 acquainted with. 



Ord. XXXII. BIGNONIACEiE. Juss. 



1. Bignonia? obovata (n. sp.); fruticosa v. arborea, foliis oppositis simplicibus obo- 

 vatis brevissime petiolatis membranaceis integerrimis basi acutis apice brevi-acuminatis 

 parallelim nervosis supra glabris subtus pallidioribus reticulatis ad nervos pubescenti- 

 hirsutis, racemo terminali paucifloro, pedicellis brevibus, calyce oblongo-tubuloso e foliolis 

 quinque exterioribus sensim minoribus 2 int. unitis apice bilobo, corolla? tubo calyce ter 

 longiore sursum dilatato limbo 5-lobo lobis amplis rotundatis patentibus. 



Hab. Realejo. — I can find no description of this fine species, which may perhaps be referred to Spa- 

 thodea. The leaves are 4-6 inches long, membranaceous, penninerved, the nerves obliquely transverse, 

 numerous, parallel. The flowers 2-3 inches long: corolla apparently yellow. There is no specimen of 

 fruit : but Dr Sinclair has put up with the specimens the dissepiment of a capsule which is 5J inches long, 

 oblongo-elliptical, chartaceous, much thickened at the margins on both sides : seeds numerous, obcordate, 

 with an exceedingly broad, delicate, membranaceous wing, marked with radiating nerves.

Hab. Realejo. — The specimens entirely agree with Humboldt and Kunth's figure.

1. Wigandia scorpioides (Choisy in Mem. Soc. Phys. Gen. 6. p. 117) ; elata, herbacea,
