gracillimis sed non obscuris, subremota. Silicula minor, 

 minus turgida quam eae varietatum aliarum. 



Plant annual. Radical leaves small, very numerous, as- 

 cending, cordate, entire or obscurely 3-5-lobed, dull green, 

 not fleshy, petioles very slender, hair-like, soon dying down. 

 Lower cauline leaves stalked, not usually exceeding radical 

 leaves, upper all stalked, decreasing in length with distance 

 from root, hederate, leaves and stem often tinged with 

 purple brown. Stems frequently single, slender, erect, 

 simple or branched, wiry, sometimes forming close tufts. 

 Flowers opening rather widely. Fruiting racemes length- 

 ening considerably and falling over. Pods small, scarcely 

 flattened at the ends, less swollen than in (a) or (c), pedicels 

 rather long, li~2 times length of pod. In its early stages 

 this variety bears a strong resemblance to Saxifraga tri- 

 dactylites, Linn. 



Common on south English coast, and also recorded from 

 v.c. 1, 5, 58, 91, 102, 103, 106, and from Ireland. 



(c) Agglomerata, var. nov. — Planta robusta. Radix 

 annua vel perennis. Caules nunc multi e basi orientes, 

 nunc solitarii, plerumque contracti ; ramuli saepius recto 

 angulo abeuntes, et frequenter caule (centrali) longiores, 

 et nonnunquam fere verticillati. Folia nitentia ; radicalia 

 rosulam formantia magis carnosa quam ea varietatis typicae, 

 late ovata, integra vel obscure lobatula, basi vix cordata ; 

 superiora caulina saepe pro specie permagna late hastata, 

 remote et obtuse serrata vel integra, in petiolum subalatum 

 brevissimum subcomplanatum gradatim angustata, vel 

 subsessilia, nervis utrinque obscurioribus. Racemi saepius 

 vix elongati ; flores (et fructus plerumque) arete compacti, 

 multi simul aperti. Silicula major quam eae varietatum 

 aliarum. 



Plant annual or perennial, robust. Radical leaves many, 

 forming a rosette, thick, fleshy, ovate, entire or obscurely 

 lobed, scarcely cordate at the base, petioles rather short, 

 stout. Leaves large, lower cauline leaves stalked similar 

 to radical ones, or occasionally more distinctly 3-5-lobed, 

 upper cauline leaves very shortly petioled or subsessile, 

 lamina broadly hastate, serrate or entire, narrowing into 

 the broad, flattish petiole. Main flowering stem stout, 

 short, deeply furrowed, branches many, at right angles to
