This section is from the book "The Gardener's Monthly And Horticulturist V20", by Thomas Meehan. See also: Four-Season Harvest: Organic Vegetables from Your Home Garden All Year Long.
In the October number of the Monthly, G. J. B., says "these two Geraniums are alike in habit, foliage, petiole, truss and color." I think he has got only one of the varieties; it may be he has got one of them under both names, as they are sufficiently distinct not to be mistaken the one for the other, and distinct enough to be grown under their separate name, although you recommend adopting one name for both kinds. Were I to order Guillon Mangalleon from Mr. Meehan, or any other nurseryman and get Archbishop Wood, I would undoubtedly consider I had got quite a different variety, both in habit and color of the flowers. I shall give descriptions of both kinds taken from plants growing under the same treatment and in the same house, hoping they may assist G. J. B., in knowing which of them he has got, for I do not think he has them both.
Guillon Mangelleon: Stem partially erect; joints showing prominent nodes and leaf; scars very large; leaves medium size, flat, not deeply indented and faintly zoned; flower trusses medium size; individual flowers large on long footstalks; foot-stalks of a deep chestnut hue; upper petals of flower deep scarlet; lower petals rosy scarlet with a slight hue of purple invading the center.
Archbishop Wood, habit compact, almost dwarf; branching, and of very free growth, covering a good space; nodes and leaf - scars not so prominent as in G. M.; leaves above medium size, not flat; serration and lobes very prominent, deep green and very faintly zoned; flowers large; foot stalks not colored or very slightly colored; upper petals rosy scarlet; lower petals of a decided purple shade, which invades the whole flower.
