Lobelia 1 spicata Lam.— In my neighborhood this is the 

 earliest blooming Lobelia. The plants are scattered and are 

 neither so attractive to insects nor so easily observed as the 

 next species. The flowers are white and are arranged in 

 rather loose spikes. They are proterandrous, like the other 

 species which have been observed. The corolla tube is 4-6 

 mm. long, and the nectar is therefore only readily accessible 

 to tongues of medium length.
