126 WILSON EXPEDITION TO CHINA 



Ser. 2. UNIFLORAE Graebner in Bot. Jahrb. XXIX. 126, 129 (emend.) 

 (1900). 



5. A. macrotera Render, n. comb. 



Linnaea macrotera Graebner & Buchwald in Bot. Jahrb. XXIX. 131 (1900). 



Hup eh: 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 

 obtusiuscula 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 cm. longa, 5-8 mm. lata. Pedunculi uniflori, axillares 

 in apice ramulorum brevium, medio bracteis duobus subulatis ciliolatis, apice 

 bracteolis quattuor ovatis ciholatis instituti; sepala oblonga, obtusa 8-10 mm. 

 longa, glabra; corolla infundibuliformis, calyce triplo longior, 3 cm. longa, infra 

 medium anguste tubularis, e medio apicem versus ampliata, limbo patulo, 1.5-2 

 cm. 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.

Linnaea uniflora, A. Braun & Vatke in Oesterr. Bot. Zeitschr. XXII. 291 

 (1872). Graebner in Bot. Jahrb. XXIX. 131 (in part) (1900). 



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. Ghraebneriana, 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. 



8. Abelia Graebneriana Rehder. See p. 118. 



9. Abelia Engleriana (Graebn.) Rehder. See p. 120. 



10. Abelia Koehneana Rehder, n. comb. 



Linnaea Koehneana 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.
