Bartlett, A. W., Note on theoccurrenceol" an abnormal 

 bispor angrate strobilus of Larix europaea DC. (Ann. Bot. 

 XXVII. p. 575—576. 1913.) 



This note describes a conc of Larix europaea which bore nor- 

 mally developed megasporophylls in the apical region, and micro- 

 sporophylls below, the two being separated by a narrow zone of 

 small sterile scales. Sevcral of the microsporophylls adjoining the 

 abortive sporophylls bore a downwarldy directed process of tubulär 

 form between the two microsporangia.

 XXVI. p. 623-624. 1912.) 



The object of this note is to define the outstanding differences 

 between the views on meiosis held by the 'Telosynaptists' (Montgo- 

 mery. F'armer and Moore, etc.) and the 'Parasynaptists' (Gregoire 

 and his pupils, etc.). It is shown that the question at issue does not 

 consist in Telosynapsis and Parasynapsis as etymologically under- 

 stood, but in different views as to the interpretation to be placed 

 on the much earlier stages of prophase in the hetcrotype mitosis. 



The author recapitulates the views on the meiotic phase which 

 he published in 1905 and draws attention to certain facts brought 

 to light b}'' recent cytological work which he regards as materially 

 strengthening his position. Agnes Arber (Cambridge). 



Hill, A, W., The Floral Morphology ofthe Genus Sebaea. 

 (Ann. Bot. XXVII. p. 479-489. 1 pl. 2 textfigs. 1913.) 



The genus Sebaea {Gentianaceae), which contains about 100 

 spccies, is diplostigmatic, that is to say, in addition to the apical 

 Stigma, secondary stigmatic patches are borne on the style below 

 the level of the anthers in nearly all the species examined. The 

 secondary Stigmas, which are placed at right angles to the lobes 

 of the apical stigma, appear to represent the lower part of the 

 edges of these lobes, which have become separated from the apical 

 Stigma by the intercalation of a non-papillated portion of stylar 

 tissue. The flowers of Sebaea are protandrous, and the anthers open 

 in the bud; the poUen is thus shed on the secondary Stigmas which 

 are situated about the level of the throat of the corolla. Self-fertili- 

 zation can thus be effected without difficulty, though cross-fertiliza- 

 tion is not precluded. As a result of the artificial poUination of 

 these secondary Stigmas, after removal of the apical stigma in the 

 bud, seeds were formed from which plants have been raised. Fewer 

 and poorer seeds were formed as a result of pollinating the termi- 

 nal Stigma alone. 



It is suggested that the peculiar condition of these flowers may 

 be compared to an abbreviated type of heterostylism modified to 

 ensure self-rather than cross-pollination. Cases of peculiar types of 

 stigmatic arrangement in other generaof this Family are mentioned, 

 and in particular the normally heterostyled genus Exochaeniuvi. It 

 seems not unlikely that heterostylism may be proved to exist in at 

 least one species of Sebaea. Agnes Arbes (Cambridge).
