SHOKT NOTES. 377 



species grow in Colorado in many places side by side, and show 

 characters that are unmistakably distinct, and never do they show 

 any tendency to vary towards each other. The differences are not 

 only in the surface of the leaves and stems, but the pods are quite 

 unlike. The specimens of A. hisjnila that are found in California 

 are almost identical with those found in Colorado. If any merging 

 of species is to be done, A. intermedia ought to go into A. plati/ceras; 

 but A. hispida, never. I have been especially interested in these 

 species, and have had opportunities of studying them in the field 

 for several years. The foliage of A. hispida is pale green, densely 

 covered with short crimped bristly hairs, short spines on the mar- 

 gins and veins of the leaves, very dense on the stems. The pod is 

 closely covered with slender bristles of varying lengths, instead of 

 the coarse horn-like spines peculiar to A. platyceras and A. intermedia. 

 In growth A. hispida is more compact, and the flowers are on shorter 

 peduncles ; in fact, almost sessile. The seeds of A. platyceras have a 

 light-coloured prominent raphe, and the coat is honeycombed. A. 

 hispida has a less prominent raphe of the same colour as the coat, 

 which is less deeply pitted; the seeds are larger. The pods of A. 

 hispida are invariably oval, and when they dehisce the segments are 

 acuminate. In A. j^latyceras the pods are cylindrical and veiny, and 

 the segments are acute. In regard to the time of blooming : in 

 Colorado, near Denver, the two species are in bloom from the 

 middle of June until the end of September, and I do not doubt but 

 that specimens could be found in bloom in October in some years. 

 The two kinds grow at Denver, Colorado Springs, Pueblo, Trinidad, 

 and I have seen them along the railroad track between those points 

 as I was travelling through. The differences are so plain that I 

 can recognize the two species at a glance, and as far almost as I can 

 see them. — Alice Eastwood, San Francisco. 



Carum Bulbocastanum in N. Hants. — On May 6th the Eev. 

 E. P. Murray and I found this plant in some plenty over about 

 twenty yards of ground by the road-side, about half-way between 

 Liss and Petersfield. It was evidently an introduction here, but 

 whether from a distance, or from the neighbouring chalk, we have 

 no means of judging. Further search may possibly show that it is 

 a native of the district. — Edward S. Marshall. 



Medicago lupulina var. Willdenowiana (p. 315). — This plant 

 was recorded by me in Journ. Bot. 1890, 229, as M. Inpulina var. 

 scabra S. F. Gray, with "glandular hairs on the fruit," from Iffley, 

 Oxford. I have seen it in Berkshire and Devon, and Miss C. E. 

 Palmer tells me she has gathered it near Odiham, in Hampshire. —

Dorset Plants. — Filayo apicnlata 0. E. Sm. occurs on ground 

 gone out of cultivation half-way between Branksome and Parkstone. 

 It has been known for years in the adjoining District I. of the 

 Hampshire Flora, but had hitherto escaped notice in Dorset. 

 Saponaria Vaccaria L., very fine and plentiful in a fodder crop 

 of vetches and white mustard on the downs south of Melbury 

 Abbas (near Shaftesbury) ; apparently introduced with the vetches.
