36. Echinus Lour.' — Flowers monrecioiis or more rarely dioecious 

 (nearly of Suinhavia) apetalous ; male calyx 2— 5-partite, valvate. 

 Stamens go, inserted on central elevated subdilated eglandular re- 

 ceptacle ; filaments free or connate at base ; anthers introrse or more 

 rarely extrorse ; cells rimose adnate or free below (Fodadema^), 

 sometimes inserted below dilated connective, discrete. Female calyx 

 3-0 -partite, valvate or more rarely more or less imbricated. Ger- 

 men free, 3-locular or rarely 2-5-locnlar, surrounded by hypogynous 

 disk of varied form {Mchmole^ns^ Blumcodendron,^), or oftener ; cells 

 1-ovulate; style branclies simple, sometimes more or less dilated, 

 largely and thickly papillose within. Staminodes hypogynous oo,^ 

 or much oftener 0. Fruit capsular, 2-5-coccous, more rarely with 

 difficulty or scarcely dehiscing [Coccoccras^) and subfleshy (Poda- 

 deni/t), unarmed or sometimes echinate [Rottlcropiik'' Melanolcpk) 

 or aculeate [Axenfeldia ^), more rarely dorsally carinate or more or 

 less sometimes long horned ( Cordemoya^ Coccoeeras) ; seeds exarillate 

 or more rarely at micropyle slightly carunculate ( Coccoeeras). — Trees 

 and shrubs ; leaves alternate or more rarely opposite, 2-stipulate, 

 penninerved or digitinerved, sometimes peltate, entire dentate or 

 lobed, oftener below sprinkled with dusky or yellow glands ; indu- 

 mentum simple, stellate or 2-morphous. Flowers terminal, axillary or 

 lateral, racemose or spicate ; spikes or racemes subsimple or oftener 

 ramified, bearing glomerules or cymes ; calyx generally ecalyculate or 

 sometimes {Diplochlamys^'^') in female flower bracts 5, in involucrum 

 representing external calyx." {Asia^ Warm Asia., Oceania and Africa}^)
