42 THE AZALEAS OF THE OLD WORLD 



Japan: Kyushu, prov. Chikugo, Koradai, near Kurume, April, 

 1918, K. Akashi; without locality, May, 1918, B. Miyazawa. 



In this plant the calyx is normal but the stamens and pistil are petaloid. Aka- 

 shi's specimen has rather small flowers salmon-red in color and is from a sponta- 

 neous plant. Miyazawa's is in size and color typical Kaempferi with double flowers. 

 He told me this was also from a wild plant. 



A form with petaloid calyx forming hose-in-hose flowers and which 

 also has been found wild is: — 



Rhododendron obtusum var. Kaempferi f. Komatsui Wilson, 



n. comb. 



Rhododendron Kaempferi var. Komatsui Nakai in Tokyo Bot. Mag. XXIX. 

 [261] (1915). 



A form with monstrous flowers may be designated: — 

 Rhododendron obtusum var. Kaempferi f. monstrosum Wilson, 



n. f. 



Korea: prov. Keiki, cultivated, said to have come from Japan, 



Agricultural Experimental Station, Suigen, May 24, 1917, E. H. 



Wilson (No. 8482). 



In this curious plant the corolla is white and has a petaloid calyx, the pistil is 

 abnormal and in most flowers is changed to a staminode, the stigma being changed 

 to a swollen, abortive anther which is often conspicuously aristate. The flowers 

 though hose-in-hose are as large as those of ordinary Kaempferi. Possibly this is 

 the same as Nakai's f . album. 



A form with abortive or nearly abortive corolla is: — 

 Rhododendron obtusum var. Kaempferi f. cryptopetalum Wilson, 

 n. comb. 



Rhododendron ledifolium S. cryptopetalum Maximowicz in Mem. Acad. Sci. 



St. Petersbourg, se>. 7, XVI. No. 9, 36 (Rhodod. As. Or.) (1870). — Matsu- 



mura, Ind. PI. Jap. II. pt. 2, 462 (1912). 

 Rhododendron Kaempferi f. f . Kinshibe Komatsu in Tokyo Bot. Mag. XXXII. 



[43] (1918). 



Japan : Hondo, prov. Kawachi, Yamomoto, cultivated, May 8, 

 1918, E. H. Wilson; prov. Musashi, Hatagaya, cultivated, April 29, 

 1914, E. H. Wilson (No. 6593). 



This is a monstrous form long cultivated in Japanese gardens under the name 

 of " Kinshibe-tsutsuji." The corolla may be entirely suppressed or represented by 

 from 1 to 5 deeply Iaciniate, strap-shaped lobes. The stamens vary from 5 to 10 

 (usually 7 to 10) ; the filaments are variable in length, often curled, bright crimson 

 in color, and may be either normal in shape or slightly flattened and petaloid; the 

 anthers are yellow. It has no garden value, being simply a curiosity. As to its 

 specific identity there can be no question, and I am at a loss to understand why 

 Maximowicz referred it to R. ledifolium (R. mucronatum G. Don).
