2 NOMENCLATURE 



ommendations of the last International Code of Botanical No- 

 menclature. 



The new terms neosystematics and hiosystematy are not used 

 here, as they seem based on an overemphasis of the fact that in 

 recent times genetics and ecology have provided some new evi- 

 dence to be included with the morphologic in reaching taxonomic 

 judgements. 



A very effective way of training botanical students in nomen- 

 clature is by having them take part in the doing of it. This is 

 easily arranged and supervised by assigning the students jointly 

 or singly to solve a series of nomenclatural cases. Each student 

 who is assigned a case investigates it, finds and evaluates each 

 publication cited, searches for other pertinent facts, for other 

 names, such as homonyms, nomina conservanda, etc., then, when 

 ready, reports on the case. The student gives his interpretations 

 before the class, the members of which serve as the jury. Que- 

 ries and arguments bring out the features of the case. The in- 

 structor, serving as judge, guides the discussion, confirms the 

 opinion of the jury, or, if necessary, gives his own judgement. 

 This method of presentation has proved stimulating to the in- 

 dividual students. 



There is given below, as an example, the case of Cydonia 

 Cydonia, and the process, step by step, of its investigation and 

 solution. The others can be digested and solved in a similar 

 way, and the study of a series of these cases will aid in giving 

 students a sounder training in botany. 



Solution of a Sample Nomenclatural Case 



Cydonia Cydonia (L.) Pers., Syn. PI. 2: 40, 1807. 



Pyrus Cydonia L., Sp. Pi. 480, 1753- 



Cydonia Ohlonga Mill., Card. Diet., ed. 8, Cydonia No. 1, 1768. 



C. vulgaris Pers., Syn. PI. 2: Corrigenda for p. 40, 1807. 



The earliest of these names is Pyrus Cydonia, which is found 

 in Linnaeus' Species Plantarum, 1753. There on page 480 

 Linnaeus published this name for the quince tree, found on the 

 rocky banks of the Danube. This name appeared in his printed 

 book, which was offered for sale in 1753» hence, it was effec- 

 tively published, under Art. 29 (1956), which states, "Publica-
