Western Hupeh: Fang Hsien, woods, alt. 1300-2000 m., May 

 21 and 26 and October 1907 (No. 769; tree 6-14 m., 0.3-2 m. circum- 

 ference, flowers violet-purple, throat yellow).^

Western Szech'uan: Yung-king Hsien, alt. 1250 m,. May 1904 

 (Veitch Exped. No. 4207; tree 7 m., flowers lavender, fragrant); Wa- 

 shan, common, alt. 300-1300 m., June 1908 (No. 3170, in part; tree 

 12-20 m. tall, circumference 1-2 m.). 



Wilson's No. 3170* lacks the long hairs on the young branchlets, petioles and 

 veins, and the young leaves are thinly tomentose beneath with glabrous veins, 

 otherwise in the shape of the calyx and in the inflorescence it agrees with Wilson's 

 No. 4207 which answers the description of P. Fargesii in every respect, except that 

 the flowers, according to Wilson's note, are lavender, though in the dried state they 

 certainly look white. A picture of this tree will be found under Nos. 47 and 79 of 

 Wilson's photographs and also in his Vegetation of Western China, Nos. 330 and 

 331. Henry's No. 10831 from Mengtze, Yunnan, agrees in many respects with 

 Wilson's No. 3170% but the leaves are more densely pubescent, about as much as 

 those of P. tomentosa ; the flowers are mauve colored according to Henry's notes and 

 are shorter and broader; in the shape and tomentum of the calyx, however, the 

 two specimens perfectly agree. 



* A new species related to P. tomentosa is the following: 



Paulownia glabrata Rehder, n. sp. 



Arbor ramulis pallide flavo-cinereis glabris. FoUa membranacea, anguste 

 triangulari-ovata, acuminata, basi truncata, 15-18 cm. longa et 11-12 cm. lata, 

 maturitate laete viridia, concoloria, supra glabra pilis sparsis ad costam nervosque 

 exceptis, subtus fere glabra pihs sparsissimis stellatis exceptis; petioU glabri v. 

 apicem versus puberuh, 4-9 cm. longi. Flores desiderantur. Panicula fructifera 

 sine pedunculo circiter 20 cm. longa; rhachis glabra; cymae 2-3(-4)-florae, pedun- 

 culo partiali circiter 1 cm. longo glabrescenti insidentes; pedicelli 1.5-2 cm. longi, 

 fulvo-tomentosuli; calyx extus intusque dense fulvo-tomentosus, ultra medium 

 partitus, lobis oblongo-ovatis obtusis. Capsula ovoidea, subito in rostrum con- 

 tracta, 3 cm. longa, tomentosula.

It is with some hesitation that I describe this specimen without flowers as a new 

 species, but it can neither be united with P. tomentosa K. Koch, which it resembles 

 in the inflorescence, nor with P. Fargesii Franchet, which it resembles in its leaves. 

 The former species differs in its broader leaves cordate at the base and always, even 

 late in the season, tomentose beneath and in its broader and shorter calyx-lobes, 

 while P. Fargesii Franchet is distinguished by its triangular-ovate, acutish calyx- 

 lobes, by the calyx-tube glabrous on the inside, by its glandular ovary and by the 

 almost sessile cymes of the inflorescence which gives it a narrow, thyrsoid-like 

 look; at the base it bears usually two elongated equally thyrsoid branches.
