 LOBELIA Linn. 



Calyx five-toothed or lobed. Corolla slit open on the upper side to near the 

 base, five-lobed, the two upper lobes half the length of the corolla, forming an 

 upper lip, the three lower united into a tridentate or trifid lower lip. Stami- 

 nal tube free from the eorolla, the two lower anthers or all bearded at the top with 

 a tuft of short stiff hairs. Style shortly two-lolied, with two patches or a ringlet 

 of short hairs below the lobes. Capsule two-celled opening at the top into two 

 loculicidal valves. Seeds numerous, small, with a thin smooth testa. — Shrubs or 

 arborescent plants or mostly herbs. All the Hawaiian species are shrubliy. 

 Peduncles one-tlowered. arranged in terminal braeteate racemes or spikes. 



The genus Ijobelia consists of over two hundred species distributed in the 

 tropical and temperate regions of all continents, with the exception of Central 

 and Eastern Europe and Western Asia. Of the Hawaiian species, which num- 

 ber eleven, Lobelia (jhiria-)iiontis, L. Gaudichaudii, and Lobelia Kauaeiisis are the 

 most beautiful of all our Lobelioicleae. They inhabit the summit of moun- 

 tains like Konahuanui on Oahu. Waialeale on Kauai, and Puukukui on West 

 Maui. Ijobelia liypoleuca and Lobelia nenifolia are of second rank. Originally 

 the gemis included five Hawaiian species of which one species L. macrostaclnjs 

 had been separated from Lobelia and a special genus had been erected for it 

 owing to the peculiar dehiscence of the capsule (see Trematolobelia). Lobelia 

 (jloria-tHontis and Lobelia Eernyi are here described for the first time. The for- 

 mer was included liy HiUebraud with Lobelia Gaudichaudii, and the latter rep- 

 resented an undescribed species in the Paris Herbarium. It is here named after 

 its discoverer the celebrated Jules Remy, who botanized in these islands during 

 the years 1851-1855. All in all there are here described eleven s])ecies, four 

 varieties and one form.
