最近天章屬竄紅,身邊的肉肉也要開花了,根據IHSP上面的資料,補上一些圖,幫天章做個記錄。

天章屬有28個品種species,(但每個品種又有好多的形態),特徵是像穗狀的花序和容易掉落的葉片。

A genus of 28 species, characterized by spike-like inflorescences and easily falling leaves.

天章屬的屬名來自於希臘字的厚/堅固+花軸,意指堅固的次(小)花梗。

Gr. 'hadros', thick, sturdy; and Gr. 'mischos', flower stalk; referring to the stout pedicels.

天章屬原生於南非和奈米比亞。

Adromischus is endemic to RSA and Namibia with concentrations of species in the Succulent Karoo of the Western Cape as well as in the Little Karoo.

直立到匍匐的小型常綠多肉,光亮到帶有粘質,多年生,高達20公分。

Erect to procumbent small evergreen succulent glabrous to viscid perennial herbs to ± 20 cm;

(本圖儲存格式不同CMYK,顯示出來有點失真,更不幸的它是遺照。)

支幹:多肉,圓柱帶有平滑到易剝除的皮,通常短小收縮。

Branch succulent, terete with smooth to peeling bark, often short and contracted;

葉片:完整,背腹清楚、緊縮到圓柱尖頭,灰色到帶有斑點的綠色,開花帶粉(這我還要再觀察),光亮或腺體─細毛,線性,橢圓,卵形到倒卵形到棍棒形(尾端較粗),葉基楔形(窄三角形),葉端鈍形,有時會有波浪;

Leaves entire, dorsiventrally compressed to almost terete, grey to mottled green, often with powdery bloom, glabrous or glandular-hairy, linear, elliptic, ovate to obovate to clavate, base cuneate, apex obtuse, sometimes undulate;

(以下的部分未拍攝到照片,先將英文的描述初步翻出,拍攝到照片後,再來補充;好消息是已經看到天章有品種在抽花序了)

花序:尾端直立,像穗狀花序(主軸是無限總狀花序,分支是有限聚繖花序)。高55公分,開1-5朵花。

錦鈴殿的花序
