Peroneuti/pa heieracanilioides {Sjihaeriaceae) appearing as minute 

 black pustules on the wood, and Jliipoxj/lon microsporum {Sphae- 

 riaceae) which causes black charcoal-like eruptions on the Ijark.

 eruptions on the hark Avas collectcil Ijy Baker at Singapore. 



CiNXAMOMUM CAMPHORA, Xccs. {Luurineae) Camphor. 



One of the Avorst troubles affecting this plant is a " thread 

 blight " which weaves a regular white cobweb over young specimens 

 even up to 12 ft. high, and eventually smothers them. It was 

 described by Bancroft in 1911 and was referred doubtfully to a 

 species of Corticium or Hypochnus. No ))ractical remedy has yet 

 been suggested for removing it as it is difficult to treat young trees 

 growing in the jungle. 



Bancroft also reports Hyrnnwchaete noxia (Thehphoraceae) 

 as causing a root disease, and Fomes lignosus; and Brooks that 

 Pink Disease has been found on this tree. 



Quite recently specimens from Selangor that have presented 

 the symptoms of ' die back ' have been collected. A black Sphae- 

 riaceous fructification was found on the bark, but the work on 

 these specimens is not yet completed. 



CiNXAMONUM iNERS, Bl. {Laurliicae) . 



Baker reports that he found Micro.njpliium iencllum on dying 

 leaves of this plant in the Singapore Gardens. 



CiTKUs ACiDA, Roxb. (Rufaceae). The Lime Tree. 



Although one would expect several pests of this tree to have 

 been collected, the only one recorded is that by Baker from Singa- 

 pore, namely, Cladosporiuni ejcrjans,. var. singaporense (Denia- 

 iiaceae) collected on dying leaves. 



Citrus medica, Linn. (Ruiaceae). The Citron. 



SphaerosHlhe coccophila (Hypocreacene) found by Bancroft 

 is not really parasitic on the tree l)ut on the scale insects which so 

 frerpicntly infest trees of this kind. 



Citrus, sp. (Ruiaceae). 



Brooks reports a case of Pink Disease on the "Lime," but the 

 exact species is not indicated. 



Clerodendron PExnuLiFLORUM, Wall. (Verhenaceae). 



Tetrachia dngularis {Tnhercrdarinceac) is recorded by Baker 

 as being found on living leaves at Singapore.
