Islands. It has larger leaves than the common Buxus . 



"Bignonia tweediana. This handsome climber is remark- 

 able for the fishhook-like tendrils which cling most 

 tenaciously to any object. It is said to have hand- 

 some, large yellow flowers and appears to be very sat- 

 isfactory for covering walls. 



"Platanus. Dr. Trabut says that the plane tree 

 commonly grown in Algeria and southern France is a 

 hybrid of P. orientalis with P. accident alis. The trees cer- 

 tainly show a great deal of variation and forms can 

 be seen which resemble either of the supposed par- 

 ents. Dr. Trabut says that the tree is easily prop- 

 agated by cuttings. 



"Gingko. Dr. Trabut says that this tree is easily 

 grafted, which I had not known to be the case. 



"Grape hybrids. At the Viticultural Station at 

 Rouiba we saw a great number of hybrids between Euro- 

 pean and American grapes, Vitis Berlandieri being the Amer- 

 ican parent which gives the most satisfactory hybrids 

 for Algerian conditions^ Dr. Trabut says that there 

 is a high positive correlation between round and un- 

 lobed leaves with resistance to drought and to calca- 

 reous soils. 



"Grapes. Dr. Trabut has some very interesting va- 

 rieties from the Kabyle mountain region in his col- 

 lection. One variety which we tasted, known as 'Amo- 

 krane', is a large white grape somewhat softer than 

 the 'Flame Tokay' (which Dr . Trabut believes to be also 

 of Kabyle origin) but firm enough to ship well. It 

 has more flavor than the 'Flame Tokay' and is moderate- 

 ly sweet and very refreshing. Dr. Trabut says that 

 the variety known as 'St. Jeannet', grown in the Alpes 

 Maritimes in France, is similar but superior to the 

 'Amokrane'. He says that all Kabyle grapes being grown 

 from seed must be selected carefully for reproduction, 

 inferior strains being often included under the same 

 name as good ones . 



"Walnut. Native Kabyle races of the Persian wal- 

 nut (J. regia) do very well at Algiers, while French 

 varieties do not. The latter succeed best on /. nigra 

 stock. 



"Kabyle varieties of grapes and walnuts are usu- 

 ally grown from the seed and, according to Dr. Trabut, 

 are much more likely to come true from seed than Euro- 

 pean varieties which are vegetatively propagated. 



"Artichoke. Dr. Trabut has a very interesting series 

 of artichoke seedlings and hybrids in his experiment- 

 al garden at Maison Carree, some of the forms having
