Cyanca tvitomantha grows in conijiany with Ch rniontia rornilea, Cltrmontia 

 parviflora, Antidcsmn platyphylhii)!, Fn ijcinctia arborea, Straussia, etc. The 

 young leaves of this species resemble greatly those of Cyaiica iioliinctaitgcre ; in 

 fact, the young plants of the former may easily lie mistaken for mature ones of 

 the latter when not in tiower.

 the herbarium of Bishop iluseum. 



The Avriter did not find this variety in the Berlin. ]Ierl)arium nor in the (Iray 

 Herbarium. Recently the Bishop ^Museum acquired by purchase from Mr. J. 

 Lydgate a collection made by Dr. W. Plillebrand ; the Lohdioidcac of the col- 

 lection were carefully examined by the writer and among the plants there v.-as 

 found this rare variety. It was hrst named Cyanca Lydgatei sjl n. by Ilille- 

 brand, but later in his Flora referred to Cyanca tritomantha as a variety ft. It 

 differs from the species in the smaller leaves and muricate corolla lobes.
