With Plate XL, 
IV. The Haustorium of Loranthus aphyllus. 
HE preparation described in this note has long been in 
X my hands. There is little probability of my being able 
to make it the basis of a more thorough investigation. What, 
however, has been ascertained seems of sufficient interest to 
place on record. 
The culture of parasitic plants, at any rate from warm 
countries, in Botanic Gardens is attended with obvious dif- 
ficulties and has hitherto met with little success. One of 
the most remarkable is Loranthus aphyllus which grows in 
Chili on Cereus Quisco . It attracted the attention of my 
friend the late Professor Moseley, F.R.S., during the voyage 
of the ‘ Challenger, 5 as it has often done that of other travellers. 
On his return to England he suggested to me that it might 
be practicable, as cuttings of a Cereus can generally be 
rooted, to import pieces with the Loranthus in situ and 
cultivate them at Kew. Acting on this suggestion I applied 
to the well-known botanist, Dr. R. A. Philippi at Santiago. 
He took much kind trouble to comply with my request, and 
in 1877 sent me the desired specimen in a box.
