in distribution as Virginia and West Virginia; a shrubby form of Azalea arborescens Pursh is 

 discussed, which grows at Great Falls, Virginia; and Azalea neglecta sp. nov. is described. 

 — P. A. Mum. 



1550. Brewster, A. A. Flowers of Haeraodorum, blood root. Australian Nat. 4: 152. 

 1920. — A semi-popular note on the form and number of the floral parts. The flower opens to 

 a very limited extent, but pollination by "honey lovers" is inferred from the nectaries. Size 

 and color are referred to only as "this seemingly insignificant 'black' flower." If black, it is 

 striking. — T. C. Frye. 



1551. Davidson, A. New or noteworthy additions to the flora of southern California. 

 Bull. Southern California Acad. Sci. 19: 54-56. 1920. — With distributional notes of various 

 flowering plants there is a description of a new species. Allium montigenum Davidson. — 

 Roxana Stinchfield Ferris. 



1552. Fernald, M. L. Rubus recurvicaulis Blanchard, var. armatus n. var. Rhodora 

 22: 168. 1920. — This new variety strongly simulates R. tardatus Blanchard, in its bristly 

 inflorescence, but has the leaflets broader and rounded at the base as in typical R. recurvi- 

 caulis which occurs with the variety, and to which it intergrades. Specimens have been 

 collected in Newfoundland, Miquelon, and Cape Breton. — James P. Poole. 



1553. Fernald, M. L., and K. M. Wiegand. Studies of some boreal American Cerasti- 

 ums of the section Orthodon. Rhodora 22 : 169-179. 1920. — Pursuant to their studies of New- 

 foundland and Labrador collections of Cerastium, the authors here publish the result of their 

 investigations of the American species of the section Orthodon, the plants of which have 

 passed in America under the composite species C . alpininn L., C. vulgatum L., and C . arvense 

 L. They recognize the following species, varieties, and forms: C. alpinum L., C. alpinum 

 var. legitimum Lindblom, C. alpinum forma puVvinata Simmons, C. alpinum var. glandu- 

 liferum Koch., C. alpinum var. glutinoso-lanatum Facchini., C. alpinum var. lanatum (Lam.) 

 Hegetschw., C. Beeringianum Cham. & Schlcht., C. Beeringianum var. capillare n. var., C. 

 Fischerianum Seringe, C. arcticum Lange, C. Earlei Rydberg, C. terrae-novae n. sp., C. 

 ierrae-novae forma Waghornei n. f., C. unalaschkense Takeda, C. vulgatum L., C. vulgatum 

 var. hirsutum Fries., and C. arvense L. Bibliography and synonymy are given except for the 

 last species. In this case the authors state that all their attempts to reduce the species- 

 complex to definite species or varieties with natural ranges have proved futile. — James P. 

 Poole. 



1554. Godfery, M. J. The problem of the British marsh orchids. Jour. Botany 58: 286- 

 290. 1920. — Orchis latifolia was studied at Vence, Alpes Maritimes, France, last May where 

 0. maculata was entirely absent. Instead of a large proportion of plants with unspotted 

 leaves and a wide variation in the markings of the lip very little of either peculiarity was 

 found. The spots were almost always present, and were either ringed or solid. The author 

 is convinced that O. latifolia of this region is identical with the spotted-leaved marsh orchis 

 of Great Britain. 0. latifolia in Vence is certainly not a hybrid of some species with 0. 

 maculata, which is absent. The suggestion that 0. praetermissa Druce is the true 0. latifolia 

 has no foundation. The spotted leaved British marsh orchis is probably simply 0. latifolia, 

 and not a hybrid. Confusion has arisen through the erroneous identification of hybrids as 

 0. latifolia. With the recognition of 0. latifolia as a species the problem of the British marsh 

 orchis is much simplified. The question as to whether there are unspotted forms of 0. latifolia 

 distinct from 0. praetermissa remains unsolved. — K. M. Wiegand.
