Perama galioides var. hispida (H.B.K.) Steyermark.

Mattuschkea hispida H.B.K. Nov. Gen. & Sp. PI. 2: 271. 1817.

The type collection of Mattuschkea hispida H.B.K., basionym of Perama hispida, was collected by Humboldt and Bonpland from '' arenosis humidis prope Atures Orinocensium" (Nov. Gen. & Sp. PL 2: 271. 1817). I have not seen the holotype, but have interpreted the topotype collections of Chaffanjon 177, A. Gaillard 267, and Williams 13089, as representing the plant described by Humboldt and Bonpland. These topotype collections are in agreement with such items in the description as: "ramis . . . hispidis," "Folia terna, linearia ant linearilanceolata, hispidula," "Calyx . . laciniis margine hispido-ciliatis." Although the leaves in the Williams 13089 and Gaillard 267 specimens are slightly broader and less generally linear or linear-lanceolate, the Chaffanjon 177 collection is a better match in this respect. However, all three collections exhibit the pubescent leaves and stems. Since the lower portion of the stems in the Williams 13089 collection has spreading hairs, I have interpreted the Metttuschkea hispida as a taxon having spreading hairs on the lower part of the stem.

Of the collections cited above two are atypical. One (Maguire, Wurdack, d; Bunting 37614) with the outer surface of the corollas glabrous and with the spreading leaves glabrate to only sparsely pubescent may represent a hybrid between var. galioides and var. hispida. It is placed in the var. hispida because of the spreading hairs on the lower portion of the stem. The other, represented by Maguire, Wurdack, Keith, & Maguire 41667, has the heads elongated to 17 mm long, varying from 5-17 mm, but otherwise appears to be referable to var. hispida f. hispida.
