Plants of two species of Oenothera took the inoculation quite 

 readily in three clays, both on leaves and stems. The inoculated 

 area turned brown at first and then black. Both terminal and inter- 

 calar sporangia were produced on the surface. 



Salpiglossis variabilis, Gilia nivalis and mixed spp., Clarkia 

 elegans, Schizanthus return and mixed spp., and Fogopyrum esculentum 

 became victims of the inoculation. Only young seedlings were 

 experimented upon. 



Opuntia Dillenii and two species of Cereus could not be inoculat- 

 ed even through wounds or on growing points. Cacao fruits and 

 apples, even when wounded, did not take the inoculation. The 

 fungus could not attack leaves and corms of Colocasia antiquorum, 

 seedlings of Lepidium sativum, cuttings and plants of Panax, tobacco, 

 Cleome sp. (even when incubated at 18°C), four species of Jasminum, 

 Phaseolus lunatus and Phaseolus vulgaris. Areca nuts, only when 

 inoculated through wounds, produced a copious aerial mycelial 

 growth in four days (Plate IX B). Sporangia were borne 

 on long stalks, they were not sessile as in Ph. omnivora. var. 

 Arecce. ' 



In June, 1912, Sesamum indicum was sown in a field where castor 

 was grown the previous year. Stray castor seeds fallen from the 

 pickings of that year had germinated in June. About fifty per cent, 

 of them were attacked by Phytophthora. When the seedlings of 

 Sesanuun indicant grew up amidst these surroundings they were found 

 to be attacked by a Phytophthora. The leaves had blackened and 

 got curled exactly like the leaves of potato attacked by Ph. 

 infestans. The attack was not very severe, only a few seedlings 

 being killed outright. \\ remained confined only to seedlings about 

 eight to twelve inches in height. The sporangia resembled in size 

 and shape those of the castor Phytophthora. The zoospores success 

 fully inoculated castor seedlings, producing the same effecl on them 

 as if they were inoculated with Ph. parasitica. Seedlings of Sesa- 

 mum indicum produced the characteristic leaf curl when inoculated
