OF BUCKLEYA QUADKIALA, B. Eï 11. b 



So far as my knowledge goes, there is no literature specially 

 concerned in the study of Buekleya. G. A. Chatin, in his 

 elaborate work, " Anatomie comparée des végétaux (Plantes [»ara- 

 sites)," has given a study of Buckley a disliehophylla among others, 

 but he has given nothing about the structure of its root-system. l) 

 A comparative anatomy of the Santalacese was then made by M. 

 Behm, 2) who has studied all known species of Buekleya, viz., B. 

 distichophylla, Quadriala and umbellulala ; but his purpose was 

 to lind out some anatomical characters for identifying sterile 

 specimens, so that he confined himself merely to an investigation 

 of the structure of leaves and stems, leaving the root-system 

 entirely out of account. It seems to me that the genus Buekleya 

 has till now been considered as an autophyte ; for example, it 

 was included by Ci-iatix, in his above cited work, among " plantes 

 non parasites." 3) 



There is, however, good reason to think that he did not 

 examine the root, because even a most superficial examination of 

 the root-system should be quite sufficient to convince one of its 

 parasitic nature. 



As to the structure of the haustorium in the Santalacese the 

 works of PiTRA, 4) Solms-Laubacii 3) and Scott' are especially in- 

 structive. PiTKA studied the anatomy of the haustorium of Thesium 

 ramosum ; Holms confirmed, in T. pratense, the results of Pitra's
