Sprague, T. A., The synonymy and distribution of the 

 species of Triciispidaria. (Bulletin of Miscellaneous Information, 

 Royal Botanic Gardens, Kew. N". 1. p. 10—16. 1907.) 



The author first discusses the relationship between Dtibousetia 

 and Triciispidaria which have been united by Baillon, but kept 

 distinct by most other systematists. The exomorphic differences are 

 of doubtful generic value; they lie in the former genus having free 

 sepals, entire petals, and 25 — 35 stamens, whilst Triciispidaria has 

 more or less united sepals, trifid petals, and 15—20 stamens. 

 According to L. A. Boodle the anatomical differences are unim- 

 portant. In the present case the two genera are not regarded as 

 cogeneric, although they constitute a well-defined group with an 

 'old-oceanic' distribution. Triciispidaria is endemic in Chili (inhabiting 

 approximately Drude's Chilian wood region); Dtihousetia is endemic 

 in New Caledonia. Only two species of Triciispidaria {T. lanceolata 

 Miq. and T. dependens Ruiz. et Pav.) are known. Their synonymy 

 is dealt with in great detail, but cannot be entered into here.

 p. 337—338. illustr. August 1906.) 



This species was not quite accurately described by Grisebach, 

 the seeds in particular being stated to be winged. This Statement is 

 shown to be incorrect by the new diagnosis. F. E. Fritsch. 



Wright, C. H., The Chinese species of Eriocaulon. (Bulletin of 

 Miscellaneous Information, Royal Botanic Gardens, Kew. N'\ 1. 

 p. 3—4. 1907.) 



The author publishes a key to the (14) Chinese species of 

 Eriocaulon. Two main sections are based on the stems being elongated 

 and densely covered with leaves (incl. E. setaceiini L.) or short 

 with radical leaves (incl. the remaining species). In the latter section 

 E. nipponicum Maxim, with 2-merous flowers is distinguished from 

 the remaining species with trimerous ones. In the section with 

 trimerous flowers further subdivisions are based on the characters 

 of the bracts, leaves, sepals, corolla etc. The author also comments 

 on the geographica! distribution of these species of Eriocaiilou.
