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. Petersburg, ser. 7, XVI. No. 9, 36 (Rhodod. As. Or.) (1870). Matsu- 



mura, Ind. PL 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 laciniate, 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).
