MONADELPHIA. PENTANDKIA. 77 



acute, the palate smooth, marked with 2 confluent white 

 spots, in the centre of which are 2 greenish dentures, and 

 2 other spots of the same green colour towards the base 

 of the tube. The height of the plant is from 1 1-2 to 2 

 feet. 



8. * gracilis. Stem erect, minutely scabrous, simple or 

 filiformly branched; leaves oblong-linear, minutely denti- 

 culate, partly obtuse and remote; flowers slenderly race- 

 mose^ distant; peduncle coloured, shorter than the flow- 

 er, bibracteate at tlie base; segments of the calix subu- 

 late, longer than the capsule which is obtuse below. Hab. 

 On the dry margins of sandy swamps, from New Jersey 

 to Carolina, and appears to be the plant which Michaux 

 had considered as a variety of the preceding, to which it 

 in many respects approaches, though perfectly distinct. 

 It is the smallest and most slender species in the United 

 States, approaching the South African species particularly 

 L. Erinoides, though unquestionably different. The radi- 

 cal leaves are spathulate and mostly hirsute; stem leaves 

 remote, sessile, scarcely ever exceeding an inch in length. 

 Stem filiform, often somewhat flexuous, but erect. Pe- 

 duncles only 2 or 3 lines long, in the flower blue; seg- 

 ments of the caUx nearly double the length of the csp- 

 Kule. Flower blue; palate of the lower lip marked wiih 

 2 acute white lines, and 2 greenish spots with 2 others 

 also near the base of the tube. The root is slender but 

 apparently perennial. 9. injlata. Stem erect and branch- 

 ed; leaves ovate, subserrate, longer than the peduncles, 

 0:ipsule globose, inflated.— According with the habit of 

 this genus, as it regards North America, the present spe- 

 cies is hirsute towards the base, but smooth above, there- 

 fore !Mr. Pursh's interpolation of the term " hirsutissima'* 

 in this instance will mislead rather than instruct. 10. 

 syphilitica. Leaves ovate-lanceolate, subserrate, sinuses of 

 the calix reflected. II. cavdijialis. Flowers bright scar- 

 let; the tube of the stamina exseited beyond the corolla. 

 Obs. L. fiilgtms has never yet been discovered in the Uni- 

 ted States, tiiat species was introduced into Europa 

 from Alexico by tl;e celebrated traveller Humboldt; See 

 a note in the first volume of his Travels, chap. Ir p. . . . 



A genus containing at present near 100 species almost 

 peculiar to America, South Africa (the Cape of Good 

 Hope,) and Australasia; with the exception of the United 

 States; the numerous and splendid species indigenous to 

 America are chiefly tropical; Europe affords but 3.
