Pedately cut, pedatifida. Cut into two lobes, and each

Helleborus niger, H. foetidus. PI. 5, fig. 1. 
Comblike, pectinata. Feather-cut leaves, the lobes being 
straight and placed parallelly like the teeth of a comb. 
Lavandula dentata, Achillea pectinata. 
Parted, partita Mirbel, secta De Candolle. Side 
incisions penetrating to the middle rib of the leaf the pa- 
renchyme being interrupted by the division ; and the Ion-., 
gitudinal incisions beyond two-thirds of the face. 
Two-parted, bipartita. Divided into two, by a very deep 
longitudinal incision. Bidens tripartita, Passiflora incar- 
nata. 
Five-parted, quinque-partita . Ipomea quinque-loba. 
Many-parted, multi-partita. Consolida regalis, Trollius 
Europaeus. 
Palmate, palmata. Many-parted leaves, with longitu- 
dinal divisions like fingers. Ipomaea quinque-loba, Passi- 
flora caerulea. PI. 5, fig. 7. 
Forked, dichotoma. Ceratophyllum demersum. 
Feather-parted, pennatipartira Mirbel, pinnatisectus De 
Candolle. Cut sideways to the middle rib of the Jeafi the 
parenchyme being interrupted by the divisions. Valeriana 
Sibirica, Polypodium unitum. 
Twice feather-cut, Bipennaticisa. The segments of the

Twice feather-parted, Bipennatipartita. 
Thrice feather-cut, Tripennaticisa. The secondary seg-

15. Composition. 
Compound. Folia composita. Footstalk not divided, 
but bearing several leaflets. 
One leafletted, unifoliata. A jqinted footstalk bearing 
only one leaflet. Citrus Aurantium, Rosa simplicifolia, 
Hedysarum vespertilionis, &c. Analogy, and the joint 
of the footstalk, causes these to be considered as compound 
leaves. 
Fingered, digitata , palmata De Candolle. Leaflets ter- 
minating the common footstalk, like fingers, instead of 
being placed on the side. 
Two-fingered, bidigitata , digit ata-bifoliolata , binala Lin- 
naeus. No example known. Zygopbyllum Fabago, quoted 
by Linnaeus, is one-paired.
