4. CORYLUS, Linn. ; M. Brit. Ind. v. 625. 



Pith more or less circular, buds witli imbricate scales, branclalets and 

 petioles often with glandular hairs, 1. serrate, basal n. 3-5. $ catkins hairy, 

 drooping, fascicled or 2-3 on a common peduncle, stamens 4 attached on the 

 inside of a broad bract, supported by 2 bracteoles, which are half or more 

 than half adnate to the bract, filaments either with 2 contiguous but distinct 

 anther-cells, or more or less irregularly bifurcating, each arm bearing an 

 anther-cell, tufts of hairs at the apex of anther-cells. 9 spikes small, lateral, 

 sessile, ovoid, bud-lik^, consisting of numerous imbricate bracts, the fl. in 

 pairs in the axils of a few of the uppermost bracts. Perianth adnate to the 

 ovary, minutely toothed, soon obliterated. Each fl. surrounded by 2 or more 

 minute scales (involucre), which enlarge in fr. and form a leafy usually lobed 

 sheath, the lobes sometimes spinescent. Nut hard, woody or bony. The thick 

 oily cotyledons remain underground in the fr. wdien germinating. Species 7, 

 Northern hemisphere.
