CAPRIFOLIACEAE — LEYCESTERIA 311 



Viburnum calvum seems most nearly related to V. pundatum Don, which is 

 easily distinguished by the larger acuminate leaves lepidote below and by the 

 sessile or subsessile much larger and lepidote inflorescence. 



Viburnum laterale Rehder, n. sp. 



Frutex? ut videtur robustus; ramuli hornotini glabri, pallide brunnei, annotini 

 pallide griseo-brunnei, sparse lenticellati ; gemmae stellato-tomentosae. Folia mem- 

 branacea, ovata v. elliptica v. ovato-oblonga, superiora anguste elliptico-oblonga, 

 acuminata basi rotundata v. late cuneata, 7-12 cm. longa et 4-7 cm. lata, dentato- 

 serrata, dentibus breviter acuminatis patentibus, utrinque glabra, supra laete viridia, 

 Bubnitentia, subtus pallidiora, nervis utrinsecus 6-9 leviter curvatis in dentes exeun- 

 tibus; petioli 1-2 cm. longi, glabri, estipulati. Corymbus umbelliformis 4-5 cm. 

 diam., in apice ramulorum brevium lateralium bifoliatorum pedunculo 5-6 cm. 

 longo gracili glabro insidens, bracteis bracteolisque parvis lineari-lanceolatis, radiia 

 plerumque 5 glabris; flores in radiis tertii ordinis, breviter pedicellati v. fere ses- 

 siles; ovarium oblongo-ovoideum, glaber, circiter 2 mm. longum; calycis dentes 

 ovati, acuti v. obtusi, circiter 0.7 mm. longi; corolla deest; stylus crassus conicus, 

 sepala paullo superans. Fructus desideratur.

 kong Bot. Gard. No. 2771, in Herb. Arnold Arboretum). 



Though neither the corolla nor the ripe fruit of this plant are known, there can 

 be no doubt that it is a distinct and well marked species. There are only few species 

 with lateral inflorescences and from all of them V. laterale is easily distinguished 

 by its glabrousness; it seems nearest to V. amplifoUum Rehder, which differs be- 

 sides in its pubescence, in the larger corymbs and in the longer and cylindric style. 

 Viburnum Colcbrookianum Wallich, which is sometimes nearly glabrous, is easily 

 distinguished by its oblong and longer leaves and by the corymbs being borne on 

 leafless branchlets. 



Viburnum erosiun Thunberg, Fl. Jap. 124 (1704) — Maximowicz in Bull. Acad. 

 Sci. St. PHersbourg XXVI. 491; in Md. Biol. X. 669 (1880). — Sargent in Garden 

 & Forest, IX. 85, fig. 9 (1896). —Rehder in Sargent, Trees & Shrubs, II. 116 (1908). 



A variable and apparently rather common species in Japan and Korea. 



Viburnum erosum, var. Taquetii Rehder, n. var. 



Viburnum Taquetii L^veille in Fedde, Rep. Nov. Sp. IX, 443 (1911). 



A typo praecipue differt foliis angustioribus oblongo-lanceolatis grosse dentatis 

 V. inciso-dentatis saepe trilobatis. 



Korea: Quelpaert in silvis Yungsil, alt. 1000m., August 12, 1910, E. J. Taquet 

 (No. 4281). 



A very peculiar and distinct looking plant, but hardly specifically separable from 

 V. erosum, of which it is apparently only an abnormal form.
