these as distinct genera; lie raised Psittacanthus, subgenus 4^to7i- 

 thuSf EicliL, to generic rank, and revived the genus Gaiadendfon^ 

 G. Don. ; Eichler had included the latter inPhrygilanthuSy wherea* 

 Benthani recognized PhrygiJafithus and Gaiadendron as distinct 

 sections of Loranthus. 



In 1894 Engler revised the African species of Loranthus, and 

 established a new section, Ischnanthusy distinguished from Tapin- 

 anthuB bv tetramerous flowers.* He divided the section Dendro- 

 phthoe into 16 series, and Tapiyianthus into four. DendroplithdCy 

 series Oleaefolii, was based on Loranthus elegans. Cham. & 

 Schlecht,, M-hich, following Harvey, he erroneously identified with 

 L. oleaefoliusj Cham. & Schlecht. The African species on which 

 Tapinanthvs, Blume, was originally based, were included in Tapi- 

 nanthus, series Constrictiflori. In 1895 Engler reduced the section 

 Tapinostemma to Plicopetahis,'f 



Engler published a revised classification of Loranthaceae in 1897, 

 adopting as sections or series of Loranthus many groups which Van 

 Tieghem had published in the meantime as independent genera. J 

 He restored generic rank to Lo.tantheray Blume, and recognized as 

 valid Van Tieghem's genus Peristeihium, He divided Lorantliua 

 into four subgenera, sixteen sections and fifty-three series. Two 

 of the subgenera were composed of both sections and series, one 

 included series only, and the fourth one sections only. 



For the details of Engler's classification, Nachtrag i. of the 

 -Pflanzenfamilien must be consulted. The following synopsis of 

 the African groups recognized by him may be found useful. 



Subgenus I. Euloranthus, Engl. Petals free, without basal 

 folds. 



Sect. VII. Sycophila, Engl, (only African section). 

 Subgenus II. Dendrophthoe, Engl. Petals united, without 

 basal folds; filaments without a tooth. 



This includes the African series: 4. Larifloriy 5. Amhiguif 

 9. LichtensteiniaylO. Acranthemum^ 11, Englerinay 12, Longl- 

 fioriy 14. Involutiflori, 15. Rigidifloriy 17. Cinerascen tes, 

 18. Lepidoti, 19, Cvpulati, 20 Metula, 21. Rufcscentes^ 

 22. Infundibnliformes, 23. Inflati^ 25. Hirsuti, 27. Longi- 

 calyculati. 



Subgenus III. TapinanthuSj Engl, Petals united, without 

 basal folds; filaments with a footh in front of the anther. 



Sect. L Ischnanthus- Flowers tetramerous. Series 1.

 vided with basal folds- 



Sect. I. AcTostachys, II. Euplicotepahis, III. Tapino-

 During the period 1901-1909 the following new groups were 

 described by Engler, the two last in collaboration with Krause :
