A specimen in the Bronx Gardens, Number 4359 a. on Piper adunc- 

 tum was collected at Mayaguez, P. R., Jan. 23, 1900, and determined as 

 M. glabra. Of the various species of Meliola found on Piper it can be 

 readily distinguished by the absence of setae and by the prominent 

 roughening of the perithecium. The species is very common on its wide- 

 spread host. No injury to the leaves is apparent. 



On Nectandra patens (Sw.) Griseb. 



Mayaguez Mesa, June 25, '15, 7466, June 15, '15, 7081, June 29, '15, 

 7595. Maricao, Sept. 20, '13, 4852, July 20, 8873, 8874, 8867, July 19, 

 '15, 8750, July 20, '15, 8973. 



On Simariihra tulae Urb. 



Mayaguez Mesa, June 29, '15, 7588. Mayaguez, June 15, '15, 7061. 

 El Gigante, near Adjuntas, July 16, '15, 8516. 



On Sauvagesia erecta L. 



El Alto de la Bandera, July 15, '15, 8641. Las Marias, July 10, '15, 

 8129. Maricao, July 19, '15, 8944, 8777. 



A specimen determined by Earle as M. glabra is in the Bronx Gar- 

 dens. The form on this host uniformly shows shorter, more nearly glob- 

 ular capitate hyphopodia than are found in the type. 



On Stachytarpheta cayennensis (L. CI. Rich) Vahl. 



Trujillo Alto, Aug. 15, '15, 9405. Sabana Liana, Aug. 13, '15,- 9380. 



I would add here also specimen No. 6402, Pueblo Viejo, of Heller, 

 Jan. 13, 1903, which is in the Bronx collection under the name M. cooJc- 

 eana, an evident error of determination. This form, like the last, also 

 has short head cells. Its mycelium is also less straight than in other 

 specimens of this species. 

 On Solamim rugosum Dunal. 



Las Marias, July 10, '15, 8121. 



On Solanum persicifolium Dunal. 



Quebradillas, Nov. 22, '13, 5019. 



This has short hyphopodia, similar to those of the two last men- 

 tioned.
