sun shines ; but if the weather be dull, and the sun does not make its appearance, the 

 flowers remain unexpanded. Should this continue for several days, they will decay in 

 the bud. 



Sub-Gentjs I.— TUBEEAUIA. Diinal. 

 Petals much longer than the sepals. Stamens numerous, all 

 fertile. Style straight, sometimes very short or absent. Funiculus 

 thickened upwards. Embryo coiled almost into a ring.

 are distinctly 3-nerved. Stipules none, or the upper leaves with 

 small ones. Inner sepals with a faint nerve, numerous black 

 glandular dots, and long white hairs. Petals yellow, usually with a

Cistus guttatus, Linn. Sin. Eng. Bot. No. 544. 



Pi.adical leaves oblanceolate or narrowly obovate ; lower stem 

 leaves elliptical; upper ones straji-shaped. Ptacemes without bracts 

 at the base of the pedicels. 



On dry banks. Very rare. Said to occur at Three-Castle Head, 

 Cork ; but I have seen no specimens. Rather plentiful in the 

 Avestern part of Jersey, and mentioned by Professor Babiugton as 

 occurring in Alderney. 



Ireland, Channel Islands. Annual. Summer. 



Stem 2 to 12 inches high, in the larger specimens first dicho- 

 tomously and then trichotomously branched. Ptadical leaves often 

 withered by the time the plant flowers, narrowed into a short 

 footstalk. Stem leaves sessile or sub-sessile, 1 to 2 inches long ; 

 the upper ones smaller, much narrower, often alternate, and 

 with stipules at the base. Elowers f to | inch across, in a 

 unilateral raceme. Sepals un'equal, the two outer elliptical, the 

 two inner ovate and twice as long as the outer. Petals wedge- 

 shaped, yellow, usually wdth a deep red spot at the base. Pruit 

 pedicels wiry, ^ to | inch long, generally slightly bent or curved
