 than the res^— Ain-el-Haramiyah, between Tripoli and Hums. {K. 

 Mdens, Sibth.) 



5. SCABIOSA, L. Scabious. 



Involucel 8-pitted or grooved, ending in a bell-shaped or rotate, 

 scarious crown. Calyx-limb patelliform, stipitate or nearly sessile, 

 ending in 5 awns. Corolla 5-fid. Receptacle chaffy — Herbs or shrub- 

 by plants, with capitate flowers, and many leaved involucre.

numerous than ribs. Perennials. 



1. S. ocliroleuca, L. If .3 to .5, more or less pubescent. 

 Lower leaves oblong, tapering to a petiole, crenate, or lyrate, the 

 others 1-2-pinnatisect or -partite into oblong to linear lobes. Leaves of 

 involucre lanceolate, shorter than flowers ; fruiting heads spherical or 

 ovate, .014 broad (with awns) ; awns of calyx iJ-4 times as long as 

 limb — August to October. 



Var. Wel>l>iana, Boiss. Lower leaves canescent-villous, upper 

 pubescent or glabrous — Alpine regions of Lebanon to Amanus, and 

 northward. 



Var. intermedia, Post. (Journal Linn. Soc, London, Bot. 

 xxiv., 433). Indument almost pannous. Lower leaves oblong, obsolete- 

 ly crenate, the base tapering to a long, margined petiole, the upper 

 more or less lyrate-pinnatipartite into wedge- oblong, crenate segments, 

 the lateral segments much smaller than the terminal. Flowers blue or 

 reddish — September and October — Rocky places, Amanus. This 

 variety is quite intermediate between S. ochroleuca, L., and S. Tayge- 

 tea, Boiss. et Held., and establishes the unity of the two species.

 white, radiating ; tube of involucel short, ribs and margin of crown 

 ciliate ; awns of calyx 5, twice as long as crown — Spring — Borders of 

 Et-Tih, and southward. 



3. S. eremopliila, Boiss. © .05 to.l, puberulent. Root-leaves
