126 WILSON EXPEDITION TO CHINA 
Ser. 2. UNIFLORAE Graebner in Bot. Jahrb. XXIX. 126, 129 (emend.) 
(1900). 
5. A. macrotera Rehder, n. comb. 
Linnaea macrotera Graebner & Buchwald in Bot. Jahrb. X XIX. 131 (1900). 
Hupeh: A. Henry (Nos. 6398, type, 1893). 
I refer to this species also Henry’s No. 1893, though it differs slightly in the 
thinner, less prominently veined leaves always cuneate at the base, while in No. 
6398 they are rounded on part of the branches. 
6. Abelia longituba Rehder, n. sp. 
Frutex gracilis ramulis purpureo-fuscis glabris. Folia decidua brevi-petiolata, 
elliptico-ovata v. oblongo-lanceolata, basi cuneata, plerumque acuminata, apice 
obtusiuseula mucronulataque, pauci-serrulata, supra laete viridia, glabra pilis 
sparsis ad marginem exceptis, subtus pallida, sparse glandulosa ad costam tantum 
villosula v. glabra, 1.5-2.5 em. longa, 5-8 mm. lata. Pedunculi uniflori, axillares 
in apice ramulorum brevium, medio bracteis duobus subulatis ciliolatis, apice 
bracteolis quattuor ovatis ciliolatis instituti; sepala oblonga, obtusa 8-10 mm. 
longa, glabra; corolla infundibuliformis, calyce triplo longior, 3 em. longa, infra 
medium anguste tubularis, e medio apicem versus ampliata, limbo patulo, 1.5-2 
em. diam., extus minute puberula, fauce intus subvillosa, staminibus longioribus 
styloque tubum subaequantibus. Achaenia sub anthesi 6 mm. longa, subteretia, 
leviter costata, glabra. 
Hupeh: A. Henry (No. 1356). 
Abelia longituba is closely related to A. uniflora, but from this and the other 
allied species easily distinguished by the long and slender tube of the corolla and 
the small leaves.

China: Fokien, Reeves (ex R. Brown), R. Fortune (ex Lindley). 
Of this species I have seen only specimens from cultivated plants which agree 
perfectly with the figure published by Hooker. According to Maximowicz the type 
specimen has smaller flowers and Lindley’s figure shows the leaves slightly hairy, 
but I do not think that the type and Lindley’s plant are different from the plant 
now in cultivation. Abelia uniflora has been made to include the plant of western 
China now described as A. Graebneriana, and even the Japanese A. serrata Siebold 
& Zuccarini, but the latter differs markedly in its two-flowered terminal peduncles, 
and belongs to another group, and the former, though closely related, is certainly 
sufficiently distinct to form a separate species.

10. Abelia Koehneana Rehder, n. comb. 
Li Koeh Graebner in Bot. Jahrb. XXIX. 132 (1900). 
Szech'uan: A. von Rosthorn (No. 1843). 
Easily distinguished from the allied species by the puberulous and green young 
branchlets and the very narrow leaves.
