A variant spelling of physiognomancy.

I actually have not come across any real examples of this spelling, nor does the OED or MED record any. This entry is based upon the claim of Shipley.

floromancy

Divination involving flowers; see anthomancy and botanomancy.
Not in OED or other dictionaries.

Derived from Latin flor-, combining form of flos flower.

1973 Gibson Complete Illust. Bk Div. & Prophecy (1989) 317: FLOROMANCY: Any interpretation of future prospects through the study of flowers or plants, including their colors, petals, time of planting, and where planted. Many omens concerning the gathering of flowers at Midsummer's Eve have survived to modern times; and the "good luck" commonly attributed to the finding of a four-leafed clover falls in this category.

1985 N. Drury Dict. Mysticism & Occult 90/2: Floromancy. Belief that flowers radiate vibrations and have curative properties in healing disease. According to practitioners of floromancy, flowers are said to respond to a sympathetic or hostile environment and are affected by electric shocks. Professor Jagadish Chandra Bose of Calcutta's Presidency College experimented with the effects of electrical currents on plants around the turn of the century and was convinced that plants possess a life-force or soul.
The most recent proponent of floromancy is American lie-detector specialist Cleve Backster, who wired three philodendrons to galvanometers on different occasions to see how the plants respond to nearby trauma. Backster monitored the plants as he placed a brine shrimp in boiling water nearby, resulting in its instant death. ..Backster's galvanometer reading showed significantly higher electrical resistance when the brine shrimps were being killed, than on other occasions - suggesting that the plants were responding "emotionally" to the traumas occurring nearby. Unfortunately, attempts to reduplicate Backster's experimental results have so far proved unsuccessful.

foliomancy

Either a. divination by leaves of a book, a form of bibliomancy, or b. divination by tea leaves, otherwise called tasseomancy.
Not in OED or other dictionaries.

Derived from Latin folio, ablative of folium a leaf.

frontimancy

A jocular nonce-word for a supposed method of divination using the lines on the face.

1709 J. Stevens tr. Quevedo's Com. Wks. (ed. 2) 374: There are lines in the Neck, the Forehead, the Lips, the Hams, the Elbows, and the bottom of the Buttocks..and therefore..as there is Chiromancy, there ought to be Frontimancy, Collimancy, Pedimancy, Natimancy.
