 1919. — The writer published the name Impatiens biflora forma Peasei (Rhodora 19: 116. 1917) 

 without having seen the living material, drawing up the description from the reports of the 

 collectors and from statements on herbarium labels. All agreed in describing the flowers 

 as "pink" or "roseate," while the flowers on certain herbarium specimens showed traces of 

 pink coloration. On later examination of the living plants from the type station and two 

 other localities in the White Mountains, he found that the ground color of the flowers of this 

 form is cream, the impression of a pink blossom being due to very numerous pink spots coales- 

 cent into solid patches of pink, confined to the inner surface of the spreading perianth parts. 

 This form is then, essentially, only a phase of /. albiflora but is allowed to stand, pending 

 further investigation, in view of its undoubtedly striking appearance and its segregation into 

 pure colonies. Its description should, however, be amended to read: "Perianth cream 

 colored, the pink spots numerous and coalescent, on the inner surfaces of the spreading peri- 

 anth parts, into patches of solid pink. Impatiens biflora, forma platymeris, f. nov. In the 

 typical /. biflora the petals are unequally two lobed on the outer edge, the basal lobe being 

 small, about one half the size of the dilated apical lobe. In the new form the basal lobe is as 

 large as the apical, or even slightly larger, and often slightly overlaps it, giving the flower 

 the appearance of being partially doubled. The difference is illustrated by sketches. The 

 type station is at Southbury, Connecticut, where eight plants were found intermingled with 

 the typical form. — James P. Poole.

465. Wernham, H. F. Rubiaceae Batesianae — I. Jour. Botany 57: 275-283. 1919 — 

 This paper is based on a collection of about 250 specimens made by G. L. Bates in the Yaunde 

 district of Southern Cameroons, and sent to the British National Herbarium. Of them over 

 sixteen per cent were Rubiaceae. A lengthy quotation from Bates' notes is included pictur- 

 ing the ecological conditions in certain portions of the region. Nearly all plants are woody 

 and fully half have weak climbing stems. The partial clearings of the natives revert gradu- 

 ally to forest. There is no winter and no regular time of flowering of each species, still Bates 

 thinks some regularity might be made out with study. Twenty-six species and varieties are 

 listed in this installment. References to published accounts, notes on standard character- 

 istics, on distribution, and on habit and classification are given. The following new species 

 are described: Mussaenda bityensis, Mussaenda leptantha, Sabicca Amomi, Bertiera (§ Cap- 

 itatae) bityensis, Randia (§ Euclinia) megalostigma, Amaralia palustris, A. ekotokicola, and 

 Morinda Batesii. The following new combination is made: Cephaelis hexamera (K. Schum) 

 Wernham (Uragoga hexamera K. Schum). — K. M. Wiegand.

 [Continued from Jour. Botany 57: 275-283.] — The paper contains the descriptions of eight new 

 species and notes on Tarenna eketensis Wernh. The new species are as follows: Gardenia 

 nigrificans, Oxyanthus heptactina, Atractogyne Batesii, Pavetta antennifera, Rutidea Batesii, 

 R. pavelloides, R. tarennoides, and R. Dorothea. — K. M. Wiegand.
