 Thc calyx enlarges somewhat with age and becOTies 10-ribbed and with 

 cross lines between the ribs, forming meshes. The seeds are flattish and

• Lobelia regalis Femald- Stout plants 2-3 feet high, much as in L, 

 Tupa L.,' erect and mostly simple, floriferous in the upper axils, softly 

 and minutely ashy-pubescent throughout even to the corolla and stamen 

 tube. Leaves oblong-lanceolate, often 1 dm. long, acuminate, cuneate int6 

 a short and margined petiole, callus-serrulate on the margins by minute 

 teeth about as long as the hairs, 2-4 cm. wide, gradually reduced above. 

 Flowers solitary in the axils, on slender peduncles about 2 inches long. 

 Calyx depressed-hemispehrical, about 8 mm. wide and 4 mm. highf "with 

 triangular teeth about as long as tube. Corolla fiery red, 3-4 cm. long by 

 5 cm., wide, split to the middle with all the lobes linear but the upper 



one, which is oblong. . Anther tube
