streaks. Caps, inversely heart-shaped, broad, compressed, finely 

 downy all over, as well as fringed. Seeds obovate, flat, very 

 thin ; corrugated minutely at one side.

[The Lent ibular ice, separated as an Order from Prhmdacccv, 

 see Grammar 96, are thus characterized by Mr. Brown, 

 Prodr. 429. 



" Calyx divided, permanent. Corolla monopetalous, inferior, 

 irregular, with a spur and 2 lips. Sla?n. 2, concealed 

 within the corolla, and attached to its lower part. An- 

 thers simple, sometimes contracted in the middle. Gcr- 

 men of 1 cell. Style 1, very short. Stigma with 2 lips. 

 Capsule of 1 cell, with a large central receptacle. Seeds 

 numerous, small, destitute of' albumen ; embryo sometimes 

 undivided (or monocotyledonous). 



Herbs growing in water, or in marshy situations. Leaves 

 radical, either undivided, or compound, resembling roots, 

 and bearing small bladdery appendages. Floxvcr-stallcs 

 radical, with or without small scales, resembling stipulas 

 (rather bractcas) ; sometimes furnished with whorled 

 bladders ; for the most part they are unbranched, and 

 either single-flowered, or bearing many flowers in a spike 

 or cluster. Each Jtoxver is accompanied by a single 

 bractca, rarely wanting." 



According to Richard, the embryo is monocotyledonous 

 throughout this whole Order ; and Mr. Brown has found 

 it so in Utrictdaria, but in Pinguicula he observed 2 

 very certain cotyledons. Here therefore is an exception 

 to one of those distinctions, generally presumed most ab- 

 solute ; nor is it a solitary instance. 



Although the difference between a regular and an irregular 

 Jloxver is by no means sufficient, in general, to constitute 

 a separate Natural Order, (see Luridce in Pentandria Mo- 

 nogynia) ; yet in the present case that difference is con- 

 firmed by so many additional circumstances, that few 

 Orders can be better defined, or more obvious, than that 

 of the Lentibularia,']
