Genws o algâu brown a geir ledled y byd yw Desmarestia . Fe'i gelwir hefyd yn acid weed, acidweed, [2] [3] oseille de mer , sea sorrel, [4]ウルシグサ( urushi-gusa ), stacheltang , mermaid's hair, landlady's wig, neu gruagach . [5] Fodd bynnag, gall 'sea sorrel' gyfeirio'n benodol at Desmarestia viridis . Gall aelodau'r genws hwn fod yn flynyddol neu'n lluosflwydd. [6] Mae aelodau blynyddol y genws hwn yn storio asid sylffwrig mewn gwagolau mewngellol. Pan fyddant yn agored i aer maent yn rhyddhau'r asid, gan ddinistrio eu hunain a gwymon cyfagos yn y broses. Fe'u ceir mewn parthau rhynglanwol bas.[6]
Gall amlyncu asid sylffwrig achosi problemau treulio difrifol. [7] Ond gan fod asid sylffwrig yn blasu'n hynod o sur, mae aelodau'r genws yn annhebygol o gael eu bwyta mewn meintiau niweidiol. [7]
Enwyd y genws er anrhydedd i Anselme Gaëtan Desmarest . [1]
