INVENTORY * 



64429. Citrus grandis (L.) Osbeck. 

 Rutaceae. Grapefruit. 



From Los Banos, Philippine Islands. Bud- 

 wood presented by J. E. Higgins, College 

 of Agriculture. Received September 9, 

 1925. 



In a letter of September 22, 1925, to this 

 office, T. Ralph Robinson, of the Bureau 

 of Plant Industry, states that this pum- 

 melo was noted by W. T. Swingle some 

 years ago at l Los Banos, where trees were 

 being grown under C. A. No. 1427. The 

 only name given it is " Better pummelo. 



64430 and 64431. Chaenomeles su- 

 perba (Frahm) Render. Malaceae. 



Shrubs growing in the permanent plant- 

 ing area at the Bell Plant Introduction 

 Garden, Glenn Dale, Md. Numbered 

 July, 1925, for convenience in distribu- 

 tion. Notes taken from the Journal of 

 the Arnold Arboretum, volume 2, page 58. 



64430. A handsome ornamental shrub 

 which apparently is a hybrid between 

 Chaenomeles japonica and C. lagenaria. 

 It differs from C. japonica chiefly in 

 the larger, but narrower, more sharply 

 serrate, darker green leaves and in 

 the larger deep-red flowers. From 

 G. lagenaria it differs in the smaller 

 leaves, the pubescent young branch- 

 lets, and in the more upright and 

 compact habit. 



*It should be understood that the names 

 of norticultural varieties of fruits, vege- 

 tables, cereals, and other plants used in 

 this inventory are those under which the 

 material was received when introduced by 

 the Office of Foreign Plant Introduction, 

 and, further, that the printing of such 

 names here does not constitute their official 

 publication and adoption in this country. 

 As the different varieties are studied, their 

 entrance into the American trade forecast, 

 and the use of varietal names for them in 

 American literature becomes necessary, the 

 foreign varietal designations appearing in 

 this inventory will be subject to change 

 with a view to bringing the forms of the 

 names into harmony with recognized horti- 

 cultural nomenclature. 



It is a well-known fact that botanical 

 descriptions, both technical and economic, 

 seldom mention the seeds at all and rarely 

 describe them in such a way as to make 

 possible identification from the seeds alone. 

 Many of the unusual plants listed in these 

 inventories are appearing in this country 

 for the first time, and there are no seed 

 samples or herbarium specimens with ripe 

 seeds with which the new arrivals may be 

 compared. The only identification possible 

 is to see that the sample received resembles 

 seeds of other species of the same genus or 

 of related genera. The responsibility for 

 the identifications therefore must neces- 

 sarily often rest with the person sending 

 the 'material. If there is any question 

 regarding the correctness of the identifica- 

 tion of any plant received from this office, 

 herbarium specimens of leaves and flowers 

 should be sent in, so that definite identifi- 

 cation can be made. 



64430 and 64431— Continued. 



64431. Forma alba. A form of the above 

 with white flowers. 



64432 to 64442. 



From Rabat, Morocco. Bulbs collected by 

 David Fairehild, agricultural explorer, 

 Bureau of Plant Industry. Received 

 July 6, 1925. Notes by Doctor Fairehild. 



64432. Arisarum vulgare Targ. Toz. 

 Araceae. 



A wild aroid which occurs in large 

 quantities in the black gumbo soils 

 around Kenitra. The medium-sized 

 tubers, produced in this soil, are eaten 

 by hogs. 



64433. Biarum bovei Blume. Araceae. 



An aroidlike Arisarum, but produc- 

 ing larger tubers, found in black, 

 sticky gumbo soil, about 60 miles north 

 of Kenitra. R. Maire, of the University 

 of Algiers, recommended it because it 

 grows so abundantly and because the 

 hogs are very fond of it. 



64434. Gladiolus byzantinus Mill. Iri- 

 daceae. 



From the cork forest of Mamora, near 

 Rabat. A slender delicate species with 

 purple-red flowers and much more grass- 

 like in habit than the cultivated forms 

 generally. It might give delicacy of 

 form to hybrids. 



For introduction of seeds, see S. P. I. 

 No. 64057. 



64435 to 64439. Iris spp. Iridaceae. 



64435. Iris alata Poir. 



A low-growing species which grows 

 wild in the wet gumbo soils about 66 

 miles north of Kenitra, Morocco. It 

 is a purple-flowered species, and R. 

 Maire tells me it is well worth grow- 

 ing in our borders for its large flowers 

 which appear, in Algeria, during Oc- 

 tober and November. It produces nu- 

 merous tubers on its roots. 



For previous introduction, see S. 

 P. I. No. 64190. 



64436. Iris fontanesii Godr. 



This species is very similar to Iris 

 tingitana, but is much lighter in color. 

 We found wild specimens nearly 5 

 feet high near Boulhaut, northern 

 Morocco. Both of these species being 

 bulbous, with their resting periods in 

 the dry summer, they would be better 

 adapted to southern California tban 

 to other iris-growing sections of the 

 United States. These bulbs were col- 

 lected by R. Maire. 



64437. Iris tingitana Boiss. and Reut. 



Collected near Kenitra. A very tall, 

 dark-purple species occurring wild in 

 Tangier and along the roadsides 

 throughout northern Morocco. At 

 Kenitra the Arabs brought in arm- 

 fuls of this iris, and under the elec- 

 tric light they appeared almost black.
