60 TAXONOMY OF VASCULAR PLANTS [BoT. Absts., Vol. X, 



Caprifoliaceae maj' possess them. The Caprifoliaceae if merged with the Rubiaceae run 

 to tribes in all parts of the family; since they do not remain a unit, they do not pass the test 

 "which should leave any satisfactory plant family intact." — P. A. Munz. 



358. Maiden, J. H. Notes on the colouration of the young foliage of Eucalyptus. Proc 

 Linn. Soc. New South Wales 44: 761-7G6. 1919 [1920]. — Observations on the colors, which 

 shade from crimsons and purples to greens and yellows, were made. The color is lost in a few 

 hours after the removal of the branches but may be preserved for 1 or 2 days if the specimens 

 are packed in closely shut tins. A grouping of species based on these colors is given. — Eloise 

 Gerry. 



359. Merrill, Elmer D. On the application of the generic name Melodorum of Loureiro. 

 Philippine Jour. Sci. IS: 125-137. 1919. — The genus Melodorum was proposed by Loureiro in 

 1790. Hooker and Thomson after examining the type regarded it as a plant of doubtful affinity 

 but would retain Melodorum as interpreted by Dunal and Blume. Merrill thinks it best 

 for the present to retain Melodorum as a genus closely allied to Popouna and proposes to adopt 

 Griffith's Fissistigma as a generic name for the species currently but erroneously known as 

 Melodorum. — Albert R. Sweetser. 



360. Merrill, E. D. On the identity of Aegiphila viburnifolia Jussieu. Philippine 

 Jour. Sci. 16: 449-451. PI. 1. 1920. — A study of Jussieu's type convinces the writer that it 

 belongs to the genus Elaeodendron, and he proposes E. viburnifolium (Juss.) comb, nov., 

 a species hitherto unreported from the Philippines but to be expected from the region around 

 Jolo. — Albert R. Sweetser. 



361. Neyraxjt, E. J. Materiaux pour servir a I'etude du genre Prunus. [Material to 

 serve for the study of the genus Prunus.] Proc. Verb. Soc. Linn. Bordeaux 70: 172-179. Sfig. 

 1917-1918. — Prunus elegans Clavaud is described in great detail. — E. B. Payson. 



362. Pennell, Francis W. Penstemon tenuiflorus. Addisonia 4: 79, 80. PI. 160 

 {colored). 1919. — An ornamental plant native of the central Mississippi Valley. It is closely 

 related to P. hirsutus and is here proposed as new. — T. J. Fitzpatrick. 



363. Pfeiffer, Hans. Zur Systematik der Gattung Chrysithrix L. und anderer Chrysi- 

 thrichinae. [The systematic position of Chrysithrix L. and of other genera of the Chrysi- 

 thrichinae.] Ber. Deutsch. Bot. Ges. 38: 6-10. 1920. — The author states that the genera 

 Chrysithrix, Lepironia, and Chorizandra must, on the basis of their flower structure and of the 

 anatomy of their stems, be removed from the Cyperaceae and placed in the Restionaceae. — 

 R. M. Holman. 



364. Phillips, E. P. The Natal species of the Sapindaceae. Bothalia 1 : 57-64. 1921.— 

 Twelve genera have been recorded from South Africa and of these 9 occur in Natal. — E. P. 

 Phillips. 



365. Phillips, E. P., and J. Hutchinson. A revision of the African species of Sesbania. 

 Bothalia 1: 40-56. 1921. — The results of this investigation might very well have been more 

 satisfactory had there been more field notes available regarding the situation, habit, floral 

 coloring, etc. That this information is vital in the determination and limitation of the 

 species of Sesbaiiia, at least, has been well demonstrated by Prain in his critical elucidation 

 of the Indian species. In the case of the African species the appendages on the claw of the 

 vexillum has been found a most useful and constant character. — E. P. Phillips. 



366. Piper, C. V. Two new legumes from Mexico and Costa Rica. Proc. Biol. Soc. Wash. 

 34 : 41-42. 1921 . — Phaseolus chiapasanus and Calopogonium ferrugi?ieuvi are described as new 

 species. — J. C. Oilman.
