Nat, [Paris] 25: 379-380. 1 fig. 1919.— The author describes and illustrates a new variety of 

 Bombax baonopozense P. Beauv. under the varietal name Vuilletii. Due to the strangling 

 effect of the coriaceous, deciduous calyx, the fruits assume a form suggestive of an hour-glass. 

 — E. B. Payson.

 [The polymorphism of the leaves of the common ivy of Portugal.] Bull. Soc. Bot. Geneve 10: 

 380-382. 1 pi. 1918.— The leaves of the ivy collected in various parts of Portugal present a 

 remarkable polymorphism. In spite of this variation, only one species, Hedera Helix L., is 

 present, — W. H. Emig. 



436. Pennell, Francis W. Scrophulariaceae of the local flora. V. Torreya 19 : 235-242.

 notes on synonymy and distribution are continued. A list of local specimens of the author's 

 collecting is appended, including 52 named forms. The name of the Vlth tribe is corrected to 

 read Veroniceae. [Previous installments have appeared in: Torreya 19: 107-119. Ibid.

 Kakteenkunde 29: 100-103. 1 fig. 1919. — The type was collected at Barranca Bagre near the

441. Quisxjmbing y Arguelles, E. Studies of Philippine bananas. Philippine Agric. 

 Rev. 12 3 : 1-73. 30 pi. 1919. — Most of the varieties described originated outside of the Phil- 

 ippines, having been introduced within the past few years from tropical Asia, America, 

 Malaya, and Polynesia. About 40 new varieties are described and figured, mostly referred to 

 Musa sapientum, but one to M. errans and two to M. paradisiaca. Drawings of flowers and 

 fruits, totaling 217 individual figures. — E. D. Merrill. 



442. Rangachariar, K., and C. Tadulingham. A note on certain species of Polygala. 

 Jour. Indian Bot. 1 : 44-48. 4 fig- 1919. — Four species of Polygala are considered, all obtained 

 on the estate of the Agricultural College, Coimbatore, India, as follows: Polygala sp., P. 

 Vahliana DC, P. bolbothrix Dunn, and P. chinensis L. Of these P. chinensis is the only 

 one included in Hooker's "Flora of British India," and in Gamble's "Madras Flora" only 

 P. chinensis and P. bolbothrix are listed. The other two species are merged under P. eriop- 

 tera DC. and P. chinensis L. Wight and Arnott, however, treated P. Vahliana DC. as a 

 distinct species. Characterizations are given of the four species, and notes on the synonymy 

 and relationships. P. Vahliana differs from its closest relative, P. erioptera DC, in its pros- 

 trate habit, oblong hairy leaves, villous sepal-wings, and pinkish petals. The second species 

 will be given a name in a subsequent paper. It is closely related to P. chinensis L. and is the 

 P. arvensis Willd. var. y of Wight and Arnott. P. bolbothrix is the P. ciliata (L.) of Wight 

 and Arnott. The name P. ciliata had been used before by Linnaeus for a species of Salo- 

 monia. — K. M. Wiegand.
