quaternate

They perform the same functions and bear spicules, sometimes in pairs, sometimes quaternate, each spicule being surmounted by a spore.

With this introduction we may state that the technical characters of the family are thus expressed:— Hymenium free, mostly naked, or, if enclosed at first, soon exposed; spores naked, mostly quaternate, on distinct spicules = Hymenomycetes.

I have often seen isolated plants with quaternate leaves, but only rarely have I observed individuals with more than one such leaf.

Isolated quaternate leaves are of but little interest, while the occurrence of many on the same individual indicates a distinct variety.

I had the good fortune to find two plants of clover, bearing one quinate and several quaternate leaves, on an excursion in the neighborhood of Loosdrecht in Holland.
