"Plausible and amusing as is the theory," says a correspondent,"that this name began as Himantophyllum, and dropped its H in London, the reverse happens to be true. It began in the Botanical Magazine, in 1828, as Imatophyllum, and got its H, also the n in its middle, in Germany, from Sprengel, sometime afterwards. The n was put in for a very good reason, and one that goes against your Cuyahoga correspondent's surmise. The name is said, in the Botanical Magazine, to have the first part from ' Iuas, iuatos, a thong or strap.' Now, iuus does not make its genitive iuatos , but iuavtosros, in our letters imantos-, or with the aspirate which belongs to it, himantos. As to the dropping of the H in London, the editor of the Monthly is aware that though usually dropped in ' Olborn' and 'Ighgate,' it is picked up at Hepping and ' Hessex,' and many other places around London".
