CORRECTIONS AND ADDITIONS TO VOLUME I 433 



mouth of the corolhi, sometimes being more or less shghtly exserted. Therefore 

 1 suggest the following combination : 



Syrinqa KoMAUowri, var. Sargbntiana Schneider, n. var. 



Add to the enumeration of specimens: Western Szech'uan: Wa-shan, alt. 

 2100-2400 m., July 1903 (Veitch Exped. No. 4081; shrub 1.8^.5 m. tall, flowers 

 rose). 



Syringa tetanoloba (p. 299). This species described from a meagre specimen 

 proves identical with *S. Sweginzowii Koehne & Lingelsheim (see p. 301). It comes 

 from the Sungpan region from which the seeds of the type probably had been in- 

 troduced to Petrograd by Russian collectors. 



Syringa tomentella (p. 300). Add as a synonjin: S. alborosea N. E. Brown in 

 Kew Bull. Misc. Inform. 1914, 187. The type of S. alborosea is Wilson's No. 1739 

 (Veitch Exped.), the seeds of which were collected near Tachien-lu in western 

 Szech'uan. 



Syringa Wilsonii (p. 300) . According to observations on hving plants this species 

 is scarcely different from S. tomentella Bureau & Franchet, of which even S. Reh- 

 deriana Schneider may represent only a variety. 



Syringa microphylla, var. glabriuscixla (p. 301). This variety is scarcely dis- 

 tinct and is connected by many intermediate forms with the type, the synonymy of 

 which follows: 



SiRiNGA MICROPHYLLA Diels in Bat. Jahrb. XXIX. 531 (1900). — Schneider in 

 Bot. Jahrb. XXXVl. Beibl. LXXXII. 87 (1905) ; III. Handb. Laubholzk. II. 778, 

 fig. 487 n-p, 486 z-z^ (1911). 



Syringa Dielsiana Schneider in Bot. Jahrb. XXXVI. Beibl. 82, 88 (1905); 

 III. Handb. Laubholzk. II. 778, fig. 487 g-k, 488 a-d (1911). 



To this species belongs Wilson's specimen from western Hupeh, June 1901 (Veitch 

 Exped. No. 2024). S. microphylla is in cultivation in this Arboretum, where plants 

 were raised from seeds collected by Purdom (No. 583). It flowered well in the first 

 days of June 1915 and 1916, and in 1916 a second time in August. 



Syringa Meyeri (p. 301). This species is not yet known in a wild state. F. N. 

 Meyer (according to his note in Bidl. U. S. Dept. Agric. Bur. PI. Industry, CXLII. 

 57, No. 23032 [1909]) sent cuttings from Fengtai, near Peking, Chih. " (No. 694, 

 Mar. 31, 1908). A small-leaved Lilac, bearing many panicles of purple flowers, 

 grafted upon a small-leaved Privet. Used much in forcing; quite rare and expen- 

 sive; not hardy. Chinese name Shan ting hsien." In this Arboretum S. Meyeri 

 has proved quite hardy. It is apparently a slow-growing species, forming a densely 

 branched small bush. C. S. 



Catalpa Duclouxii (p. 304). Add the following number: 



Eastern Szech'uan: Wushan Hsien, A. Henry (No. 5856), distributed as 

 Aleuriles {Elacococca cordata Muell. Arg.). 



Sambucus Schweriniana (p. 306). This species flowered at the Arnold Ar- 

 boretum for the first time in August 1914. This enables us to add the following 

 description of the flowers which were unknown when the species was described: 

 Corymbus concavus, glaber v. fere glaber, 9 cm. diam., 5-radiatus, radius medius 

 lateralibus multo brevior: flores 5-7-meri, plerumque 6-meri, sessiles v. pedicellati 

 pedicellis circiter 1 mm. longis; sepala subulata, 0.5 mm. longa, albida v. leviter
