 1870, v.8, p. 253. Dwarf and matted-erespitose, with a woody, perennial, 

 much-branched base which is usually covered with the dead leaves of 

 previous seasons ; the branchlets densely leafy up to the solitary, sessile 

 flowers, woolly-caneseent; leaves 3"-4" long, evergreen, rigid, subulate, 

 more or less acerose, scarious-connate at base, usually strongly revolute 

 on the margin, soon spreading or somewhat squarrose-recurved from the 

 appressed base; tube of the white corolla exceeding the calyx, the ob-

 otherwise smooth or sparingly glandular; corolla-tube more or less ex- 

 ceeding the calyx, lobes obovate, entire, 3" long. 



Yar. CONDENSATA, Gr. Densely crespitose, iy~2' high ; leaves short, 

 2 // -3 // long, very closely crowded, erect, imbricated. Gray's Peak, at

 at the base, glabrous or pubescent; steins erector ascending; leaves

 septum bearing t^o laminar phicenta 1 projectiii" 1 into each cell from the axis, -svhicli 

 are at rirst united, at length free. Low, annual branching herbs, perennial or some- 

 what woody nt the base, variously pubescent, with alternate or rarely opposite entire 

 leaves, and axillary and tei iiiinal Mowers. Choisy, DC. Prod, 10, p. 182.

 threads (spiricles) when wetted, (except in C. r//v<e*7/#.) Annuals or semi-biennials,
