It's hot - It's hot

Japanese: アツイタ - あついた

A fern of the Malvaceae family (illustration), known as a sclerenchyma (fern) because of its thick, flat leaves. The rhizome is short and creeping, and has dense brown, membranous, ovate scales along with the base of the petiole. The leaves are simple and lanceolate. The petiole is short and the difference with the leaf surface is sometimes not clear, and the total length of the leaf is 10-30 cm. The petiole of the sporophyll is longer than or the same length as the leaf blade. The veins are free parallel veins and are not clearly visible when the plant is fresh. The sporangia cover the entire underside of the sporophyll, which turns black-brown when the spores ripen. There are no capsules or lateral filaments.

Japanese:

葉が厚く平板状であるために厚板(羊歯)と呼ばれているツルキジノオ科のシダ（イラスト）。根茎は短くはい，葉柄の基部とともに褐色，膜質，卵形の鱗片を密につける。葉は単葉，披針形。葉柄は短くて葉面との差が明らかでないこともあり，葉の全長は10～30cmである。胞子葉の葉柄は葉身より長いか同長。葉脈は遊離平行脈で，生時ははっきりみえない。胞子葉の裏面全体に胞子囊がつき，胞子が熟すると裏面は黒褐色になる。包膜や側糸はない。
