1921] REHDER. NEW SPECIES, VARIETIES AND COMBINATIONS 177 



Ampelopsis brevipedunculata var. kulingensis Rehder in Bailey, 

 Gent. Herb. i. 36 (1920). 

 China. Kiangsi . 



This variety resembles somewhat typical A. brevipedunculata, but is 

 easily distinguished by its ghibrousncss and by the leaves being truncate 

 or subcordate at the base, remotely and sinuately denticulate and 3-lobed 

 near the apex with long-acuminate lobes. 



Ampelopsis brevipedunculata var. Hancei, comb. nov. — Vitis sinica 



Miquel in Jour. Bot. N(5erl. i. 125 (1861). — A. heterophylla var. B. Hancei 

 Planchon in De Candolle, Monog. Than. v. 457 (1887). —A, heterophylla 

 var. sinica Merrill in Philipp. Jour. Sci. xi. Bot. 128 (1916). 



This variety differs from tlie type chiefly in the smaller leaves of firmer 

 texture, slightly reticulate beneath, coarsely crenate-serrate, without or 

 with three short lobes, and like the branchlets usually glabrous or some- 

 times with a short minute pubescence on the veins beneath and on the 

 young branchlets and petioles. It is known from the Chinese provinces 

 Kwangtung and Fokien, from Formosa and the Philippine Islands, There 

 are also specimens before me from the Liukiu Islands which are probably 

 best referred to this variety, though part of the leaves resemble var. 

 Maximowiczii and part var. kulingensis. 



Columella Lour. 



It has been recently shown by Merrill (in Philipp. Jour. Sci. xi. Bot. 

 131 f 19161) tliat Columella Lourciro is the oldest name for Cayratia Jussieu. 

 Though he voices the hope tliat a future Botanical Congress wi'l include 

 Cayratia under the nomina conservanda, to avoid the renaming of Colum- 

 ellia Ruiz & Pavon and of the family of Columelliaceae, he adopts the 

 name, makes a number of new combinations and describes some new 

 species. Ae we do not know when another Botanical Congress will take 

 place and as it is doubtful what action it will take in regard to cases like 

 this, it seems best to be governed by the present rules and accept Col- 

 umella Lourciro. We may even retain Columellia Ruiz & Pavon, as it 

 differs in spelling, though only slightly. Whether we accept Cayratia or 

 Columella, new combinations cannot be avoided, as Gagne}>ain has de- 

 scribed a number of new species under Cayratia, while Merrill and Elmer 

 have done the same under Columella. At present I am concerned only 

 with the following species which is well represented in our herbarium 

 and which has been introduced into cultivation by E. H, Wilson in 1907. 



Columella oligocarpa, comb. nov. — Vitis oligocarpa Ldvcillc & Vaniot 

 in Bull. Soc. Agric. Sci. Sarthe, lx. 41 (1905); in Fedde, Rep. Spec Nov. 

 II. 159 (1900). — Cayratia oligocarpa Gagnepain in Lecomte, Not. Syst. 

 I. 348, 359 (1910); in Sargent, PI. Wilson, i. 99 (1911). — Cissus oligocarpa 

 Bailey, Stand. Cycl. Hort. ii. 775 (1914). 



Central China.
