100 NATURAL HISTORY OF PLANTS. 



GENERA, 



1. Pensea L. — Flowers hermaphrodite regular apetalous, 4- 

 merous ; perianth (coloured) shortly tubular or conical ; lobes a little 

 shorter, valvate. Stamens 4, alternate with lobes, inserted in neck ; 

 filaments very short ; anthers introrse enclosed ; connective basifixed 

 thick somewhat compressed ; cells much shorter, inferior oblique 

 rimose; fimbrilli-ciliate. Gynsecium superior; carpels 4, oppositi- 

 petalous, dilated at base (by germen), concave within, contiguous at 

 margin, valvate (not coadunate), dorsally angular apterous {Stylap- 

 terus), or oftener produced to a vertical vittseform wing to the 

 top of the style {EupencEo), at the base internally produced to a thick 

 free septum (contiguous within and hence dividing the germen into 

 four cells, not connate); styles 4, free, approximating to a 4- 

 sulcate column, cruciately dilated at stigmatose apex. Ovules in 

 cells 2, collaterally ascending suberect ; micropyle introrsely inferior. 

 Capsule clothed with augmented perianth, loculicidally 4-valvate ; 

 valves septiferous within, l-2^spermous. Seeds suberect; testa 

 crustaceous; radicle of thick exalbuminous fleshy ovoid-conical 

 embryo inferior thick truncate or concave; cotyledons 2, superior 

 very small, visible from a very short cleft or almost entirely confer- 

 ruminate. — Evergreen undershrubs ; leaves opposite imbricate, entire 

 cricoid or oftener flat coriaceous ; stipules very small lateral glandu- 

 liform (blackish); axils often setiferous ; flowers in axils of upper- 

 most leaves (sometimes changed into coloured bracts) solitary sub- 

 sessile, decussately bracteolate. [Cape of Good Hope.) See p. 95. 



2. SarcocoUa K.^ — Flowers nearly of Fencea (larger) ; perianth- 

 tube ^ oblong ; lobes shorter than tube {Eusaixocolla ^) or subequal
