思在樹人

照片1 常見的黑法師

二年生或大部分多年生，密生到少分支或單幹，有時結一次果（結果後會死亡）的次灌木或單一或叢生，次無莖（或短莖？）蓮座植物

Biennial or mostly perennial, densely to few branched or single-stemmed, sometimes monocarpic subshrubs or single or caespitose, subacaulescent rosette plants;

照片2. 明鏡和姬明鏡，葉片上面和葉緣都是纖毛。

根部 纖維質

R fibrous;

照片3. 八月的黑法師，葉片群能維持這種狀況已經不錯，推測是莖部夠粗才能提供葉片群相當的支撐。

枝幹 通常上升，團狀或扭曲，光亮或微細毛，平滑或具有網紋，有時會有明顯的葉斑

Br often ascending, partly in groups or tortuous, glabrous or puberulent (densely hirsute in A. smithii), smooth or with reticulate pattern, often with distinct leaves scars;

蓮座 平坦，新葉緊密相接，或稍微直立，或成杯狀，通常球狀，且乾季會緊緊的包覆。

Ros flattish flattish with inner L tightly appressed to each other or ± erect, or rather cup-shaped, often ± globose and tightly closed during dry season;

照片5. 鏡獅子，它的葉片相當的肥厚，夏天也不掉葉。

葉片 簡單，無柄且基底寬厚，肉質到明顯的多肉，螺旋狀，倒卵形或倒卵匙形，偶有卵形，橢圓形或倒風箏形（類似卵形但邊角比較明顯，這種形態我沒有特別去注意到），葉端尖銳、尖長、圓滑、有尾或淺凹，葉基楔形、極少數漸尖形，（這兩者的差異在楔形更尖銳、瘦長），綠色或黃綠色，有時會有粉紅或紅色的變異，光亮，成熟時會變亮或平，或帶纖毛，帶粉或黏質，通常光亮，葉緣帶有明顯直線或前彎，珠形或圓錐形單細胞纖毛（這有點不知道是什麼）

L simple, sessile with a broad base, fleshy to distinctly succulent, spirally arranged, often obovate or obovate-spatulate, occasionally ovate, elliptic or trullate, apically acute, acuminate or rounded, caudate or retuse, basally cuneate or rarely distinctly attenuate, green or yellowish-green, often variously pinkish or reddish variegated, glabrous, glabrate or pubescent, sometimes glaucous or viscid, occasionally glossy, margins often with distinct ± straight or forwardcurved, bead-shaped or conical unicellular Ha (= cilia);

（這屬的花我幾乎沒有拍到，等拍到後再來校對文字和補圖）

花序 尾端（A．simsii開在基部），通常半球狀，橢圓，或圓錐，總花梗很明顯，帶有密厚的葉片。

Inf terminal (from basal Ros axils in A. simsii), often semiglobose, ovoid or conical, peduncle distinct, often densely leafy;

Perl 1 - 16 mm, glabrous, puberulent or distinctly pubescent;

Fl (6- to) 7-to 12- (to 16-) or 18- to 32-merous, 12 - 25 mm 0;

Sep fleshy, basally connate, glabrous or pubescent;

Pet free, spreading or slightly recurved, often lanceolate or oblanceolate, occasionally obovate, commonly acute or acuminate, pale to deep yellow or whithish and then often variously reddish variegated;

St 2x as many as Pet;

Fil free, filiform, glabrous or puberulent;

Anth cylindrical, variously yellow;

NSc 0.5 - 1.5 x 0.3 - 1.2 mm, square or oblong, cuneate, sometimes absent;

Ca as many as Pet, sometimes distinctly immersed in the Rec, glabrous or often with some glandular Ha;

Se papillate or most often costate, brownish.
