LARDIZABALACEAE. — HOLBOELLIA 345 



Our specimen, which is male, differs from Gagnepain's description in its shorter 

 (1-2.5 cm. long) petiolules, longer (2.5-5 cm. long) pedicels and in the cuspidate 

 rather than uncinate leaves. In all essential characters, however, it agrees exactly 

 and we have no hesitation in referring it to Gagnepain's species. Stauntonia 

 Duclouxii is a handsome climber with large, fragrant and abundant flowers. It is 

 apparently very rare in Hupeh, as we met with one plant only.

This is distinct from any species known to us. It seems nearest, however, to 

 S. Duclouxii Gagnepain, from which it differs chiefly in its 4-6-foliolate leaves and in 

 the thinner leaflets usually obtuse and mucronate at the apex. Our material con- 

 sists only of leaves and fruit and is too fragmentary to serve as the type of a new 

 species. 



F. Gagnepain in his elaborate paper (Revision des Lardizabal^es asiatiques de 

 I'Herbier du Musdum {Bull. Mus. Nat. Hist. Paris, XIV. 64-70 [1908]) discourses 

 carefully on the classification of this family, and we agree with him in considering 

 Stauntonia and Holboellia distinct genera. The confluent filaments of the stamens 

 in Stauntonia (with which we unite Parvatia) are concomitant with the relatively 

 thin, acuminate sepals except in the case of S. filamentosa Griffith ; the free fila- 

 ments in Holboellia are concomitant with thick, fleshy, obtuse sepals. We agree 

 with Hemsley (in Hooker's Icon. XXIX. sub. t. 2843 (1907)) in uniting Decaisne's 

 Parvatia with Stauntonia De Candolle. The presence of six nectaries in both male 

 and female flowers in Parvatia and their presence in the female and absence in 

 the male flowers in Stauntonia seems too slight a character to base generic dis- 

 tinction upon.

A common climber in rocky places up to 1300 m. alt. in western Hupeh. It is 

 closely allied to H. latifolia Wallich, with which it has been confused by R^aubourg 

 and others. It is readily distinguished, however, from that species by its constantly 

 3-foUolate, more coriaceous, and less conspicuously veined leaves, by the longer 

 peduncles and longer pedicels to the pistillate inflorescence, by filaments as long or 

 shghtly longer than the anthers and by smaller seeds. The undescribcd fruit is
