SAXIFRAGACEAE. — DICHROA 43 



Western Szech'uan: Wa-shan, cliffs, alt. 1200-1800 m., July 

 1908 (No. 2569). 



Differs from the type in its thinner and smaller leaves glaucescent beneath, 

 sometimes nearly oblong in outline and in its smaller sterile flowers. 



To complete the enumeration of the Chinese Schizophragmas, the following 

 varieties and species which are not represented in the recent Wilson collection 

 are appended here. 



Schizophragma integrifolium, var. minus Rehder, n. var. 



A typo recedit foliis membranaceis, ovatis, v. subcordatis, integris v. fere integris, 

 minoribus, tantum 8-10 cm. longis et 5.5-6.5 cm. latis, supra flavo-viridibus, subtus 

 pallidioribus, sepalis florum sterilium oblongo-ovatis, acutiusculis, basi cuneatis, 

 3-3.5 cm. longis et 1-1.5 latis. 



Hupeh: A. Henry (No. 5965, type); South Washan, wet place, June 1900, 

 E. H. Wilson (Veitch Exped. No. 1065). 



Differs from the type in its smaller and thinner leaves and much smaller sterile 

 flowers. 



Schizophragma hypoglaucum Rehder, n. sp. 



Frutex radicibus scandens. FoUa chartacea, oblongo-ovata, manifeste acumin- 

 ata, basi rotundata v. late cuneata, integerrima, 8-15 cm. longa et 3.5-6.5 lata, 

 supra obscure viridia glabra, subtus glauca (sub microscopio dense papillosa), 

 glabra axillis barbatis exceptis. Cyma fere glabra; tubus calycis glaber; sepala 

 florum sterilium oblonga vel anguste oblonga, basi cuneata, apice obtusa, subtus 

 glaucescentia et papillosa, 3-5 cm. longa et 7-17 mm. lata. 



Szech'uan : Mt. Omei, July 1904, E. H. Wilson (Veitch Exped. No. 4885). 



In the shape and smoothness of the leaves it resembles much S. integrifolium, var. 

 glaucescens Rehder which has the leaves glaucescent beneath, but the species is 

 easily distinguished by the intensely glaucous color of the under side of the leaves 

 and particularly by the papillae which are entirely wanting in that variety, also 

 by the dark green upper side, the glabrous caly:x-tube and the obtuse sepals of the 

 sterile flowers. It is so strikingly different from typical S. integrifolium that it is 

 hardly advisable, though the variety glaucescens seems to represent a connecting 

 link, to consider it a variety of that species, particularly as the papillosity of the 

 under side of the leaves affords a good morphological character for separation.

 (1835). — Schneider, III. Handb. Laubholzk I. 393, fig. 252 a-i (1905). 



Hydrangea Taquetii L4veill6, in Fedde, Rep. Nov. Sp. VIII. 282 (1910). 



Korea: Quelpaert, T. Taquet (Nos. 807,808,2885). 



So far as I know S. hydrangeoides has never been reported from Korea before. 

 Taquet's No. 807 and 808 represent the type of Hydrangea Taquetii Leveill4.
