reddening lono; internodes as much as 2 cm. long in upper 

 part, prostrate at base branching above, each branch 

 ascending and ending in a single flower or some branches 

 arrested and forming iiodal rosettes whence new stolons 

 arise. Leaves of the upper region of stolons linear-filifoi'm 

 running out to a long point, as much as 2 '5 cm. long hardly 

 1-5 mm. broad hardly recurving not constricted at base, 

 epetiolate, passing at once into a vagina connate with that 

 of opposite leaf into a sheath about 3 mm. long. Flower 

 solitary terminal ; pedicel as much as 1"2 cm. long barely 

 2 mm. in diameter red. Calyx about 3"5 cm. long; tube 

 funnel-shaped not split, about 1-3 cm. long 3"5 mm. broad 

 angular, shining outside very red at the base, above some- 

 what blistered, dark-green, inside pale-green slightly rugu- 

 lose, intracalycine membrane truncate ; lobes subequal 

 distant linear-filiform to a long point, over 2 cm. long 

 about 1"5 mm. broad, not contracted at base, somewhat 

 involute dark-green erect spreading not markedly recurved. 

 Corolla obconoid-tubular about 5*5 cm. long spreading to 

 about 2 cm. ; tube within the calyx pale-green about 3 mm. 

 in diameter, above that with 5 antipetaline bands greenish- 

 white not spotted but with a central narrow faint purple 

 line and two lateral broader purple boundary ridges, inter- 

 petaline areas white tinted pale sky-blue, inside unspotted 

 white rugulose on antipetaline areas, throat striped pale 

 blue and white ; lobes 5 broadly ovate or trigonous obtuse 

 and slightly apiculate pale sky-blue about 6 cm. long and 

 broad half patent ; folds paler than lobes, about 3 nun. long 

 and 7 mm. wide, broadly triangular erose with a longer often 

 aristate tooth about the middle. Staminal filaments free 

 through 12 cm. tinted pale blue, inserted about 2-1 cm. 

 above base of corolla, narrowly winged ; anthers sagittate 

 4 mm. long. Ovary about 1'4 cm. long; stipe 2-5 cm. long; 

 style 6 mm. long its stigmatiferous branches about 1'5 mm. 



Siberia. About Lake Baikal. Bocherel. 



This species was described and figured by Burkill from 



Szechuan. The whole group consists of plants with showy flowers, but 

 G. ornata is the only one which has been in cultivation prior to the 

 introduction of G. Lawrencei. 



The flowers of G. Lawrencei are If inch long, upright, and blue above, 

 the lower part of the tube being pale, with dark blue lines. They 

 s tand solitary on the ends of ascending narrow-leaved bi'anches.
