Martiusella (after K. F. Ph. von Martius. German botanist, 1794-1868; traveled in Brazil 1817-20, wrote Historia Naturalis Palmarum and started the monumental work, Flora Brasiliensis, continued after his death by A. W. Eichler and I. Urban). Sapotaceae. An evergreen small tree from Brazil with large alternate serrate lvs.: fls. small in axillary clusters; calyx 5-, rarely 4-parted; corolla rotate, 5-6- lobed; stamens 5, inserted at the base of the corolla opposite to the lobes and nearly as long as the corolla; sometimes with staminodes between the petals; ovary 5-celled with short style: fr. subglobose, 3-5-seeded; seeds compressed; cotyledons thin. Closely allied to Chrysophyllum which is chiefly distinguished by its smaller entire lvs., the longer corolla-tube, shorter stamens and the thick cotyledons, and also by the much- branched habit. The only species is M. imperialis, Pierre (Theophrasta imperialis, Lind. Chrysophyllum imperiale, Benth. & Hook.). See also p. 767, Vol. II. Strict and simple, to 20 ft. high or more: lvs. obovate- oblong to oblong-oblanceolate, rounded at the apex, serrate with strong parallel veins, stellate-pilose beneath at first, becoming glabrous, 8 in. to 3 ft. long: fls. yellowish green. ¼ in. across, pedicelled, in axillary sessile clusters: fr. subglobose, 11/3in. long, with a hard thick flesh; seeds chestnut-brown, lustrous, about 1 in. long and ¾ in. wide. Brazil. B.M. 6823. I.H. 21:184. Gt. 13:453. —It can be grown outdoors only in frostless regions; sometimes cult. in greenhouses for its large handsome foliage. It flowers very rarely in cult., flowering first in 1885 after it had been in cult. for 40 years. Prop, is by seeds or by cuttings in March when the new growth is starting; the upper part of the plant is cut into as many pieces as there are lvs., the cuts being made just below the base of the lvs. ; the cuttings are inserted in sand under glass with bottom heat; they usually take a long time to form roots.
