TREACLE MUSTARD 



Erysimum parinHorum. Mustard Family 



Stems: erect, simple. Leaves: oblanceolate or linear, obtuse, entire 

 or dentate, the upper sessile, the lower slender-petioled. Flowers: 

 pale yellow. Fruit: the siliques elongated, linear, four-angled, valves 

 strongly keeled by a prominent mid-vein. 



This common Treacle Mustard has very small pale yellow 

 flowers and rather whitish leaves, which latter grow in a 

 tuft at the base of the plant and also alternately all the way 

 up the stiff erect stems. The flowers have four tiny green 

 sepals and four yellow petals, which latter are cruciate, or 

 set in the form of a cross. The Treacle Mustard belongs 

 to the Cmciferce, or Mustard Family, all of whose members 

 have four cruciform petals. 



STONECROP 



Sedum stenopetalum. Orpine Family 



Flowering branches erect. Leaves: alternate, crowded, but scarcely 

 imbricated except on the sterile shoots, sessile, linear, entire. Flowers: 

 in a three-to-seven forked cyme, compact ; petals narrowly lanceolate, 

 very acute, much exceeding the calyx-lobes. 



This plant is well named Scdnm, from sedere " to sit," 

 for it sits very happily, and in lowly fashion, upon the bleak 

 bald hills at high altitudes. It is a most uncanny plant. 

 The tiny, pale green, juicy leaves, crowded on the thick 

 short stems, are, like human flesh, easily bruised ; and each 

 of the bright yellow flowers, which grow in dense clusters, 

 has four or five narrow pointed petals. There are ten 

 stamens, the alternate ones being attached to the petals. 

 The five erect carpels are tipped with long conspicuous and 

 divergent styles, crowned by fat stigmas. 



The smooth clammy foliage of the Stonecrop reminds the
