PHANEROGAMS— PROFESSOR BAYLEY BALFOUR. 61 



In the present most unsatisfactory state of the genus I have not been able 

 to refer this plant to any described species, but in Kew Herbarium there are 

 specimens collected by Hildebrandt, and labelled — "n. 2321, Ixamtei in 

 Duruma. Auf Kikamba : Mussakaongo,"- — provisionally referred to the vicinity of 

 A. (Schmidelia) repanda, Baker, which belong to the small leaved form of this 

 Socotran plant. Our plant is then not endemic. I have seen no large leaved 

 forms from Africa or other locality. 



"With three African species our plant is related : — A. (Schmidelia) rubifolia, 

 Hochst. (in Ach. Rich. Tent. Flor. Abyss, i. 103 ; Baker in Oliv. Flor. Trop. Afr. 

 i. 423), A. (Schmidelia) alnifolia, Baker, and A. (Schmidelia) repanda, Baker (loc. 

 cit.) — all species of somewhat indefinite limitation, and at present including 

 forms which may eventually prove to be distinct species. But the Socotran plant in 

 any of its states is easily diagnosed. From A. rubifolia its shorter racemes and 

 pedicels, its leaves not inciso-repand, and its more globular fruits distinguish it. 

 In the other two species mentioned, petals are wanting, and they are glabrous 

 with larger inflorescences. A. alnifolia resembles it most in the form of leaf. 



2. Allophylus, sp. ? 



Socotra. On the hill slopes near Tamarida. B.C.S. n. 685. 



Specimens of a plant with coriaceous trifoliate foliage leaves, but without 

 flowers or fruit, are possibly referable to this genus, and in it to the vicinity of 

 A. (Schmidelia) decipiens, Arn. (in Hook. Lond. Journ. iii. 153), a Cape species. 

 It is, however, impossible to decide upon our imperfect material. 



2. DODON^EA. 



Dodoncca, Linn. Gen. ed. I. n. 855 ; Benth. et Hook. Gen. PI. i. 410. 



An almost exclusively Australian genus, but with a few scattered represen- 

 tatives in the tropics of the globe, and one cosmopolitan tropical species which 

 occurs in Socotra. 



D. viscosa, Linn. Mant. 228 ; Boiss. Flor. Orient, i. 953 ; Baker in Oliv. 

 Flor. Trop. Afr. i. 433 ; Hiern in Hook. Flor. Brit. Ind. i. 697 ; Francb. Sert. 

 Somal. in Miss. Revoil 20. 

 D. Burmanniana, DC. Prod. i. 616 ; Wight Illustr. i. fc. 52. 



Socotra. On Haghier hills. B.C.S. n. 659. 

 Distrib. Cosmopolitan in tropics. 



Order XXV. ANACARDIACE.E. 



A large family inhabiting tropical and warm countries. Two genera are 

 represented in Socotra, one of which is dispersed over the whole globe, the 

 other being confined to Africa and Asia.
