 XVI. NO. 8. p. 119—120. 1906.) 



Verf. gibt eine ausführlichere Beschreibung nach einem im 

 Kgl. Botanischen Garten zu Dahlem blühenden Exemplar (Erste 

 Beschreibung durch Da ms in „Gartenwelt" Bd. X p. 14.) Die Art 

 gehört zur Untergattung Dolichotele Lem. und ist von den verwandten 

 Arten ManiiUaria longhnamnta P. DC. und M. sphaerica Dietr. vor 

 allem durch die drei- bis viermal kleineren, unansehnlichen, weissen 

 Blüten unterschieden. P. Leeke (Halle a/S.)

 stachviini Kränzlin n. sp. (The Gardener's Chronicle Vol. XL. 

 3"-' ser. W. 1036. p. 302—303. 1906.) 



The genus Xylobium includes all the Maxillarioid Orchids with 

 stalks bearing more than one flower; it was formerly united with 

 Maxillaria and then reestablished. The new species complicates the 

 question of the affinity of the genus still more. Unlike other species 

 of Xylobiutn it shows no trace of affinity with Bifretiaria , but shows 

 a tendency to pass into the Stanhopea line as illustrated by the 

 presence of large sheathing bracts. The spike is unusually short and 

 the lip is a Single oblong organ without any crests or calli, such 

 as are found in Maxillarias and Bifrejiarias. X. brachystachyiini is 

 a native of Southern Brazil and appears to correspond to Kochio- 

 phyton negrense of Schlechter (fig. in Flora Brasil. Orchid. III. t. 110.)

 on Eucalyptus. Part I. (Abstr. Proc. Linn. Soc. N. S. Wales. 1904.) 



The author deals with some plants formerly included under 

 E. aniygdaUna , Labill. The confusion which has gathered around 

 E. radiata^ Hook. f. (non Sieb.), is finally cleared up. That "White 

 Gum" included under radiata by Bentham and others is described 

 as a new variety or species under the name E. nmnerosa , from the 

 number of fruits in an umbel. The name E. diversifolia , Bonpl., is 

 shown to have priorit}^ of E. saiitalifolia , F; v. M. The limitations of 

 E. odornta, Behr, E. cajiipiitea, F. v. M. , E. acacioides, A. Cunn., and 

 E. Woollsiana , R. T. Baker, are dealt with. Some observations are 

 made on hitherto unrecorded afiinities between E. alpina, Lindl., and 

 E. capitellata, Sm. E. cladocalyx, F. v.M., is shown to have priority 

 over E. corynocalyx, F. v. M. , and to include E. Cooperiana , F. v. M. 

 The ränge of E. cladocalyx hitherto supposed to be confined to 

 South Australia is thus extended to Western Australia. As 

 regards the Western Australian E. patens, Benth., E. pachyloma, 

 Benth., is recorded as a synonym, and it is pointed out that E. Tod- 

 tiano, F. V. M. , may prove to be a synonym also. It is proposed to 

 look upon E. pulvigera^ A. Cunn., as distinct from E.cordata, Labill. 

 The relations of E. piüverulenta , Sims, and E. nova-anglica , Deane 

 and Maiden, are discussed. The author shows that E. aniplifolia , 

 Naudin, hitherto looked upon as a form of E. tereticornis, Sm., is 

 worthy of specific rank. The relations of E. exserta , F. v.M., and of 

 E. Morrisi, R. T. Baker, are discussed. E. pleiirocarpa , Schau., is 

 shown to take precedence of E. tetragona, F. v.M. The "Woolly-Butt" 

 of Northern New England is described as new under the name
