190 WILSON EXPEDITION TO CHINA 
(Nos. 4064, 6370, 7664). Szech’uan: A. Henry (No. 5518). Kiangsi: 
Kuling, side of| streams, alt. 800-1300 m., July and August 1907 
(Nos. 1664, 1673). 
A well-marked species easily recognized by its sub-umbellate inflorescence 
subtended by 2 to 3 crowded subsessile leaves, and by the comparatively large flowers 
on slender glabrous pedicels. 
Photinia amphidoxa Rehder & Wilson, n. comb. 
Stranvaesia amphidoza Schneider in Bull. Herb. Boiss. sér. 2, VI. 319 (1906); 
Ill. Handb. Laubholzk. I. 713, fig. 394 k-1 (1906). 
Szech'uan: A. Henry (Nos. 5565, type, 5565", 7389). Western 
Hupeh: Changyang Hsien, alt. 1000-1500 m., June and October 
1907 (No. 405; bush 2-3 m. tall, flowers white, fruit scarlet); Chang- 
yang Hsien, woodlands, 1000-1300 m., May and October 1907 (No. 
465, flowering branch only; bush 3 m. tall, flowers white); without 
locality (Veitch Exped. No. 714, fruiting branch only). 
Schneider placed this species into Stranvaesia probably on account of its five 
styles, but neither the number of styles nor the greater or lesser degree of union 
between the back of the carpels and the calyx-tube can be made a character of gen- 
eric distinction between the genera of the Pomaceae. The fruit seems to us to agree 
exactly with that of the section Pourthiaea of Photinia except in the complete union 
of the carpels to the calyx. It has the same granulose flesh, thin papery walls, 
not separating or splitting and no central cavity, at least we have not been able 
to detect in the fruit or in the young ovary the free central space as found in Stran- 
vaesia. In the scarlet color of the fruit and the rugulose or verruculose epidermis 
it agrees also with Photinia, while Stranvaesia has an orange-red or coral-red fruit 
with smooth epidermis. Schneider refers to this species a fruiting specimen col- 
lected by A. von Rosthorn, and gives the measurements of the fruit as 9:8 mm., 
but in our specimens the fruits measure about 14 mm. in diameter; they are sub- 
globose, dark scarlet, very sparingly villose or nearly glabrous except at the apex; 
the persistent calyx-teeth are incurved; the apex of the core is villose and almost 
flat; the granulose mesocarp does not separate clearly from the endocarp, which is 
5-celled with thin papery walls; the seeds are about 6 mm. long, oblong-obovate, 
narrowed at both ends, particularly at the almost stipitate and slightly curved base. 
, Here may be added the description of three new species based on material of 
other collections than those of the Arnold Arboretum Expedition. 
Photinia glomerata Rehder & Wilson, n. sp.
