Note Standley & Steyermark (in Field Mus. Bot. 244:170. 1946) report that the sap is employed as a remedy for erysipelas around Cobain in Guatemala. Maya names for this plant are zactezxiu and zacxiu. Other vernacular names reported are pie de paloma, velo de princesa, adorno de nitzo, chancanil, tabudo, mosquito, hierba de gato, siete pellejos, coyontura, coyontura de polio, taba de gfiegfiecho and camaron. Iresine spiculigera Seub. and Iresine acicularis Standl. were first lumped by Suessenguth (in Rep. Sp. Nov. 35:319. 1934), but later separated again (in Rep. Sp. Nov. 39:13. 1935). Standley (in Field Mus. Bot. 132:517. 1937) apparently accepts the lumping and further states that J. spiculigera "is doubtfully distinct from I. celosia". Analysis of I. spiculigera with cinereous spicular pubescence, I. acicularis, with ochraceous spicular pubescence, and I. frutescens Moq., with small flowers, reveals that they are best considered conspecific with I. celosia L.
