232 LILIACEyE. 



Then comes the corona " Corona apice tubi inserta, lobis paulo brevior, ultra 

 medium in lacinias 6, staminibus alternantes, lineares, acutas, conniventes, 

 genitalia omnino velantes, fissa." I have been very much puzzled to understand 

 what is meant by the " corona." As to the stamens, it is stated " stamina 6, 

 inter coronas lobos affixa." The explanation which I shall give to the " corona," 

 judging from the position of the anthers, is that it is a cylindrical tube, com- 

 posed of dilated filaments which are united one to another and protrude far 

 beyond the insertion of the anthers, but the points of insertion are terminated 

 by the anthers themselves. In other words, the corona is a tube formed by 

 the perfectly united broad filaments which are sagittately 2-lobed at the apex 

 and have anthers at the sinus between the lobes. Then follows " filamentis 

 brevissimis ; anthers introrsis, brevibus, dorsifixis, secus margined dehiscentibus. 

 Ovarium sessile, ovoideum, trigastrum, triloculare. Stylus brevis, crassiusculus ; 

 stigma punctiforme. Ovula in quoque loculo 4, angulo interno affixa, horizon- 



talia. Bacca ? Herba rhizornatosa, caulescens, " If my explanation 



of the " corona " is correct, our plant perfectly accords with HANCE'S original 

 description in the 'generic characters. The Formosan species has filaments with 

 sagittate apex, partly united, but distinct nearly half way down. The point 

 of difference between HANCE'S species and mine is, therefore, whether the 

 filaments are perfectly united one to another or connate for half their length, 

 which however can scarcely warrant that the two are not congeneric.
