The 20th century saw some innovations in lines of partition. "Erablé", a series of alternating upright and inverted maple leaves, is a typically Canadian line of partition, though the College of Arms in London has used it in a few grants (but compare the cross "nowy erablé" in the arms of Katherina Fahlman Selinger Schaaf. A Finnish line of partition, invented by Kaj Cajander and called , which is called "fir-tree topped" in Britain, and which the Canadian Heraldic Authority coined the term "sapiné" to blazon, resembles fir trees; in the arms of Guy Selvester this is called "sapinage". A line resembling fir twigs, and so called in British blazon, is called "sapinagy" in Canada (though there is no example of it in the online Canadian Public Register), and in Finland. Other 20th-century examples of lines, or things akin to lines, include the 1990 grant to Albersdorf-Prebuch in Austria, in which the upper line of the fess takes the form of fruit, the bottom of vine-leaves. (It is debatable what the distinction is between such lines, and examples such as the arms of Bierbaum am Auersbach, a town in Styria, in which three pears grow from a pall.) The South African Bureau of Heraldry has developed the line of partition "serpentine" (which has also been called ""ondoyant""), which is rather like wavy, but with only one "wave", one complete cycle of a sine wave; the serpentine in the arms of the Mtubatuba Primary School is defined as "dexter to chief and sinister to base". (Similar is the German "" (snake-wise).) It has also developed the uniquely South-African lines of division (which can also form the ends of a charge) "nowy of a Cape Town gable" (now called just "nowy gabled"), and "nowy of an Indian cupola". Similarly, the fess line in the arms of the Council for Social and Associated Workers is "nowy of a trimount inverted", the fess in the arms of Mossel Bay is "nowy of two Karoo gable houses", the chief in the arms of the Lenasia South-East Management Committee is "nowy of an Indian cupola", the chief in the arms of the Genealogical Society of South Africa is "double nowy gably" and that of Frederick Brownell is "gably of three".
