NEW COMBINATIONS IN LATIN NAMES 



When a species is transferred to another genus, and 

 when a variety is transferred to another species or 

 associated with another species-name or reduced from 

 specific to varietal rank, the names follow them and a 

 "new combination" results. Thus, if an author desires 

 to place the almond in Prunus rather than in Amygda- 

 lus, in which Linnaeus originally described it as Amyg- 

 dalus communis, the new combination Prunus commu- 

 nis results. If Ribes leiobotrys of Koehne is considered 

 by Zabel to be only a form of R. aureum, the new com- 

 bination R. aureum var. leiobotrys, Zabel, results. 



To enable botanists and bibliographers to record and 

 trace the different dispositions and properly to under- 

 stand the varying opinions of relationships, all such new 

 combinations are entered whenever complete synono- 

 mies are made. 



In the Cyclopedia, it has been the desire to avoid the 

 making of new combinations, as explained on page xi 

 of Vol. I, although, under the exigencies of the work, 

 a very small number has arisen. In Vols. V and VI, 

 many combinations were inevitable, and these were 

 duly published in Rhodora, XVIII, 152-160 (July, 

 1916); these were largely in the genera Polyscias, 

 Pyrus, Pseonia, Passiflora, Prunus, Statice, Limonium, 

 Saxifraga, Tropa3olum. 



A list of several incidental scattered new combina- 

 tions made in the Cyclopedia itself is here given, so far 

 as desired, without histories, for 'the easy reference of 

 the bibliographer. These are such combinations as 

 the authors designed to make. Undoubtedly other 

 combinations in the use of varietal names, and in the 

 compilatory shift of other names, may be traced by 

 those who have occasion to work over special groups; 

 but these may not be considered here. The new com- 

 binations are mostly of horticultural varieties and of 

 species-forms of minor importance. Numberless asso- 

 ciations of varietal names cannot be traced to one 

 definite source, as they are found in trade catalogues, 

 periodicals, and other non-botanical publications, or 

 may be customarily employed by horticulturists; these 

 are therefore given the designation "Hort." (hortorum, 

 "of the gardens;" page xvii, Vol. I). In those cases in 

 the Cyclopedia in which no authority is given for varie- 

 ties, "Hort." is to be understood. 



The dates of the new combinations listed below are 

 those of the publication of the six volumes: Vol. I, A- 

 B, March 25, 1914; Vol. II, C-E, July 22, 1914; Vol. 

 Ill, F-K, May 12, 1915; Vol. IV, L-O. Feb. 23, 1916; 

 Vol. V, P-R, Oct. 4, 1916, Vol. VI, S-Z March 28, 1917. 

 It will be seen that most of the combinations are in 

 the latter part of the alphabet, and among the names 

 of woody plants. No new species have been described 

 in the Cyclopedia, and very few new varieties.
