19251 REHDER, NEW SPECIES. VARIETIES AND COMBINATIONS 205 



Cedrus libanotica f. nana, comb. nov. 



Cedrus Libani 3. nana Loudon, Arb. Brit. iv. 2403 (1838). — Carrtere, Traits 

 Conif. 284 (1855); ed. 2, 371 (1867).— Beissner, Handb. Nadelholzk. 301 

 (1891).— Hornibrook, Dwarf Conif. 25 (1923). 



Pinus Cedrus 2. nana (Loud.) Antoine, Conif. 57 (1840). 



This is a dwarf rather compact form, usually forming a round bush. 

 According to Carriere (1. c. ed. 2) the form cultivated as "Comte de Dijon" 

 belongs here. 



Cedrus libanotica f. pendula, comb. nov. 



Cedrus Libani pendula Knight & Perry, Syn. Conif. 42 (1850), name only. 

 Carrtere, Traits Conif. 284 (1855).— Beissner, Handb. Nadelholzk. 301 

 (1891). 



This form differs from the type in its pendulous branches and branchlets. 



It seems strange that Link's name C. libanotica, which is the oldest 

 binomial under Cedrus for the Lebanon Cedar, should have been overlooked 

 or passed over until very recently, but probably the fact that Link himself 

 in his later publications abandoned this name in favor of C. Libani and 

 did not even cite it as a synonym and that it is not cited in Index Kewensis 

 accounts at least partly for this fact. To make it clear that according to 

 the International Rules C. libanotica is the correct name for this species, a 

 complete enumeration of the synonyms known to me may follow here: 



Cedrus libanotica Link, Handb. II. 480 (1831). — Ascherson & Graebner 

 Syn. Mitteleur. Fl. ed. 2, I. 316 (1913), as synon. of C. Cedrus. — -Hayek, 

 Prodr. Fl. Pen. Balcan. (in Fedde Rep. Spec. Nov. Beih. XXX) 41 (1924). 



Pinus Cedrus Linnaeus, Spec. 1001 (1753). 



Larix Cedrus Miller, Gard. Diet. ed. 8, no. 3 (1768). 



Pinus effusa Salisbury, Prodr. 399 (1796). 



Abies Cedrus Poiret, Diet. vi. 510 (1804). 



Larix patula Salisbury in Trans. Linn. Soc. VIII. 314 (1807). 



Cedrus Libani [Barrelier, PI. Icon. 499 (1714)]. — Lawson Agric. Man. 379 



(1836).— Loudon, Arb. Brit. iv. 2402 (1838). 

 Cedrus patula K. Koch, Dendr. n. 268 (1873). 

 Cedrus Cedrus Huth in Helios, xi. 133 (1893). 

 Cedrus effusa Voss in Mitt. Deutsch. Dendr. Ges. xvi. 92 (1907). 

 Pinus Cedrus var. effusa Voss in Putlitz & Meyer, Landlex. iv. 768 (1913). 

 Cedrus libanotica subsp. C. Libani Holmboe in Bergens Mus. Skrift. n. ser. I. 



no. 2, 30 (Stud. Veg. Cyprus) (1914). 



The combination C. libani cannot be credited to Barrelier, as this is a 

 prelinnean author, neither can the combinations proposed by K. Koch and 

 Voss be accepted since they are based on non- valid names.
