Vietnam và chúng ta: SEN LẠ Ở ĐỒNG THÁP

Có một loài sen khá lạ mọc lên tại ao của ngôi chùa nhỏ ở Đồng Tháp thu hút khá đồng người đến tham quan, thưởng lãm. Đó là chùa Phước Kiển, xã Hòa Tân, huyện Châu Thành (Đồng Tháp), cách TT. Nha Mân hơn 15 cây số. Điều đặc biệt của loài sen này là người đứng lên lá không chìm. Giác Ngộ Online xin gởi đến quý độc giả chùm ảnh về loài sen này do tác giả Ngọc Dung thực hiện. Rất mong tiếp tục nhận ảnh cộng tác từ Chư tôn đức Tăng Ni và bạn đọc gần xa.

Sen chiếm diện tích lớn ao của chùa

Lá sen to quá khổ

To bằng cái nia, vành cong lên cả tấc tay trông rất đẹp mắt

Người có thể đứng lên được

Hoa sen cũng rất đặc biệt

Làm điệu cùng sen lạ

Con trai cũng không ngoại lệ

Chị và mẹ hái sen

Thương quá một góc ao quê

Victoria amazonica is the largest water lily in the world. Lilies are especially abundant in the várzea during the flood season. When the water is low, the seeds will survive drought and herbivores (such as fish) in pools on the várzea called poços (1). In the Brazilian Amazon, Victoria amazonica seeds and rhizomes are important items consumed by riverine inhabitants (2) The root, stem and seed of the lily are all edible, and the species is also used in traditional medicine (3).
