among them are the Sweetheart {Desmodiiimincanum), Crotalaria 

 retusa, C. incana, C. seriacea, Cassia obtusifoiia, Wedelia buph- 

 thahnoides, Stachytarpha cayennensis, the Cankerberry [Solanum 

 bahamense), the yellow Mimosa, Love-in-a-mist (Passiflora fcetida), 

 and a Euphorbia (? E. heterophylla), with its bracts splashed with 

 red. Emilia soiichifolia is one of the few examples of Compo- 

 sitge. 



A great number of plants occur mainly on the roadsides or 

 among the canefields. In addition to Argcmonc mexicana and 

 Sonchus oleraceus, many appear to be indigenous, being found in 

 wild places as well as in the midst of cultivation. Many Ipomaeas 

 abound ; there are numerous Leguminosae, usually twining, such 

 as the Wild Pea {Centroscma virginianun), the Winah {Tcramnus 

 uncinatiLs), and tlie Blue Pea {Clitoria ternatea) ; erect Papilionatae 

 include a Phaseolus and ^scliynoinene americana, which is sensi- 

 tive, like Mimosa. Wild Lord Lavington (Leonurus sibiricus) and 

 the Monkey Bush (Abutilon indicum) are common weeds, and the 

 Whitehead (Partheniwn hysteroplwrus) is extremely common, 

 especially along roadsides. The Stinking Weed (Cassia occi- 

 dentalis) is frequently found and several species of Salvia. 



The flowers of the undoubtedly aboriginal plants are, on the 

 whole, inconspicuous and not brightly coloured, though there are 

 exceptions. With this may be correlated the absence of the 

 gorgeous butterflies and moths found in most West Indian islands, 

 those of Antigua being small and few in number. 



UREDINALES OF NORTH DEVON. 

 By Norman G. Hadden. 



As very little mycological fleld-work appears to have been 

 done in North Devon, a Hst of the rust-fungi found there in July 

 and August, 1915, may prove of some interest to other mycologists 

 who intend to visit that charming district. All the species in the 

 following list were obtained in the immediate neighbourhood of 

 Lynton in July and August of this year, unless otherwise stated. 

 It is, I venture to think, sufficient to show that the district is 

 particularly rich in Uredinales. Several of the species recorded 

 are looked upon as very uncommon in England, notably Piiccinia 

 mrgaurecE Lib., P. crepidis Schrot., P. liydrocotyles Cooke, Cro- 

 jiartitmi quercimm Miyabe, and Milesina blechni Sydow. Puccinia 

 tinctoricB Magn. is apparently the second British record, but it 

 has since been obtained in Worcestershire by Mr. Carleton Rea. 

 Uromyces striatus Schrot. has apparently not been hitherto 

 obtained in Britain on Trifolium procumbens, though it is known 

 on the Continent on this host ; Quercus Ilex similarly is a new 

 British host for Cronartium quercimm Miyabe, of which the uredo- 

 spores only occur in this country. 



Mr. Carleton Rea has kindly verified all the determinations 

 for me, except in the case of a few of the very common species.
