草 grasses & sedges

對草有癖好。

因為千姿百態,形態色彩高度各異。如果陽光好,情緒便更高漲,因為牠們要不更亮綠,要不放射透視閃光,披一身耀眼。

愛牠們漫山遍野,風吹草動,野外好生舞動。遇到牠們在街角、石縫拔地而生,對其生命力不能不拜服。

i am fond of grasses.

they look so gentle yet they are the toughest. wind blows and grasses dance waves. their colours are fascinating, so many shades of green, yellow, brown and red and all kinds of sheen and luster. and, who won’t be awed by their vitality. they are in the most open areas and in corners and crevices , in the wild and in cities.


查閱 草,植物學上分兩大科:禾本科、莎草科,都歸於禾本目下。

我們賴以為食糧的穀物,不少屬禾本科,而我們視為草的,很多則是莎草科的。

說到莎草,就會想起古埃及的造紙。原來我們愛吃的馬蹄,亦是莎草科(荸薺屬);是多年生水生草本植物,吃的部分是其球莖。莎草通常多年生。有細長的莖與葉。稈多實心,剖面通常呈三棱形。花的排列三為一組。花被常缺,沿著小穗排列的花上退化為鱗片或刺毛。

what we generally call grasses are sedges or cyperaceae in botany. the most famous member is probably papyrus. quoting from wiki, while sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils.

 風車草 umbrella papyrus (cyperus alternifolius subsp. flabelliformis) – cyperaceae 莎草科

茳芏 (cyperus malaccensis)「鹹水草」- cyperaceae 莎草科

黑莎草 triste gahnia (gahnia tristis nees) – cyperaceae莎草科

至於禾本科,稻米、麥、玉米、甘蔗、竹均屬此科。牠們有一年生,也有多年生的。

poaceae are the true grasses. both cyperaceae and poaceae are under the order of poalae. most of the crops as well as bamboo are in the family of poaceae.

短葉黍 (panicum brevifolium l.) – poaceae 禾本科

狼尾草 chinese pennisetum (pennisetum alopecuroides) – poaceae 禾本科

薏苡 job’s tears (coix lacryma-jobi – poaceae 禾本科
