 Stems reddish, pubescent. Flowers hairy, clustered in the axils of the 

 leaves. The structure of these clusters, as explained by other species, 

 appears to be this; every cluster is a minute contracted dichotomous 

 cyme with a definite or centrifugal inflorescence : the central (primary) 

 flower, which has no stamens, is provided with two lateral bracteas ; 

 between which and the flower appears a perfect (secondary) flower, 

 having also two bracteas at its base, which uniting with the first brac- 

 teas form each of the three-lobed segments of the involucre: in 

 luxuriant specimens every secondary flower is accompanied by two 

 sterile (tertiary) flowers wdth an imperfect pistillum, furnished also 

 with two bracteas, which also uniting with the preceding bracteas form 

 two .segments, of 7 lobes a-piece. The involucre then consists^ of 

 twice as many bracteas as there are flowers, these bracteas being 

 united into two pieces or leaves, consisting of as many lobes as there 

 are flowers. Alternating with the pieces of the involucre is an ad- 

 ditional smaller external bractea on one and sometimes on both sides. 

 Occasionally in var. a., especially near the summit of the stem, the 

 secondary flowers are sterile : in j8. this also occurs, the^ tertiary 

 flowers disappearing ; more rarely the secondary flowers disappear, 

 leaving only the primary and four tertiary ones, and then every piece 

 of the involucre is 5-lobed. What Linncxus called P. Judaica, from 

 Palestine, may be a state (perhaps a monstrosity) of our var, a,, with 

 the perfect flowers longer and narrower, somewhat resembling a horn ; 

 but what is so termed in Switzerland (Hall, n. 1613) is precisely 

 our common form.
