 Ulmus, sect. A. Emdmus, II. Madocarpus Ascherson & Graebner, Syn.

 This section contains the largest number of species, but it is represented in the 

 New World only by U. fulva Michaux. 



Subsect. a. GLABRAE Schneider in Oester. Bot. Zeitschr. LXVI. (1916). 



Ulmus, series Glabrae Moss, Cambridge Brit. Fl. II. 89 (emend.) (1914). 

 This subsection is well marked by the position of the seeds in the samara, as in- 

 dicated in the key, p. 247. 



Series a. Wallichianae Schneider in Oester. Bot. Zeitschr. LXVI. (1916). 

 The species of this group, which are confined to India and eastern Asia, need 

 further observation.

Ulmus erosa Wallich, Cat. No. 3546 (noraen nudum) (non Roth) (1831). 



INDIA. Kashmir: Kishtwar, " reg. temp. alt. 8-10000 ped.," T. Thomson 

 (ex. Herb. Ind. Or. sub nom. U. campestris macrophylla; with fruits). Kumaon : 

 without precise locaUty, R. Blinkworth (type, ex Herb. Wallich No. 3546; fide 

 Planchon). 



According to Planchon's description the fruits of U. WaUichiana are hairy only 

 upon the disk containing the seed, while the wing and the margins are glabrous. 

 Unfortunately, I did not see Walhch's specimen No. 3546. Brandis (1874) de- 

 scribes the samara as " pubescent," and the plant before me agrees well with his 

 plate and also with Planchon's description of the leaves and other parts. Hooker f . 

 (1888) says: "Samara . . . glabrous or disk puberulous." I have not seen any Elm 

 from India with fruits hairy only upon the disk. There may be some mistake in 

 Planchon's and Hooker's statements; otherwise such a variability in the pubescence 

 of the fruit would be a strange fact in the genus. The Elms of British India are 

 still imperfectly known and need careful observation in the field.

 Pteroceltis.
