CAPRIFOLIACEAE — LEYCESTERIA 311 
Viburnum calvum seems most nearly related to V. punctatum 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, 
subnitentia, subtus pallidiora, nervis utrinsecus 6-9 leviter curvatis in dentes exeun- 
tibus; petioli 1-2 em. 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, radiis 
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 itisa 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. amplifolium Rehder, which differs be- 
sides in its pubescence, in the larger corymbs and in the longer and cylindric style. 
Viburnum Colebrookianum 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 erosum Thunberg, Fl. Jap. 124 (1704) — Maximowicz in Bull. Acad. 
Sci. St. Pétersbourg XXVI. 491; in Mél. 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 Léveillé in Fedde, Rep. Nov. Sp. IX. 443 (1911). 
A typo praecipue differt foliis angustioribus oblongo-lanceolatis grosse dentatis 
v. inciso-dentatis saepe trilobatis.

o. 4281). 
A very peculiar and distinct looking plant, but hardly specifically separable from 
V. erosum, of which it is apparently only an abnormal form.
