Abstract A new hybrid of the genus Fritillaria, F. ×makotoi Hitoshi Sato & Naruh., from Honshu, Japan is described. The plant is believed to be a natural hybrid between F. amabilis and F. ayakoana. This hybrid differs from F. amabilis by narrowly funnel-shaped flowers, from F. ayakoana by nectaries at almost basal part and narrowly oblong tepals.

Fritillaria ×makotoi Hitoshi Sato & Naruh., hybr. nov. F. amabilis Koidz. × F. ayakoana Maruy. & Naruh.
This hybrid differs from F. amabilis by narrowly funnel-shaped flowers, from F. ayakoana by nectaries at almost basal part and narrowly oblong tepals.
Perennial herbs with bulb. Bulbs white, globose; the scales 2, thickened, semiglobose; consisting of an old bulb and a new bulb inside at flowering. Stems simple, slender, 10-20 cm tall, erect, green, glabrous, with five leaves and a single flower. Leaves consisting of a pair of opposite leaves near the middle of the stem and 3 verticillate leaves at tip: green, entire, attenuate or obtuse at apex, acute at base, sessile, the lower pair narrowly lanceolate or linear-lanceolate, 45-75 mm long, 6-13 mm wide, the upper 3 smaller and narrower, linear-lanceolate or linear, 35-65 mm long, 2-6 mm wide. Flowers March, solitary, nodding, nearly white or pale purplish white on the vein, narrowly funnel-shaped, shoulders of flower almost the base, 17-20 mm long, 18-24 mm in diameter, with 3 outer tepals and 3 inner tepals, with pedicel. Pedicels 4-10 mm long, reclinate,

often corrugate. Tepals narrowly oblong, 18-24 mm long, 4-6 mm wide, boat-shaped in side view, with opaque pale purple longitudinal lines, lightly dull purple mottled at base, obtuse or rounded, entire. Nectaries on the inside of tepal, green or yellowish green, narrowly oblong, 4-7 mm long, from the shoulder towards the middle. Stamens 6; Filaments white, 8-9 mm long, papillose; Anthers yellowish white, narrowly oblong, 5-8 mm long, c. 2 mm wide. Pistils 1, 14-18 mm long; style white, erect, papillose, lightly 3-fid at apex; distance between stigma lobes c. 1 mm; ovary ellipsoidal, yellowish green, glabrous, 4-6 mm long.
Chromosome number: 2n=22 (Noda unpublished). Type: Japan, Honshu: Tadu, Sakurae-cho, Gotsu-shi, Shimane Pref., Mar. 23, 2018, Naruhashi no.

Japanese name: Iwami-kobaimo, nov. Etymology: The epithet of makotoi refers to Mr. Makoto Tanaka who discovered the plant. Note: The present hybrid was discovered in a few localities along the Gonokawa River in Sakurae-cho
or nearer area of the River, Ohda-shi where the one of the parents was growing at neighboring distance. As a result of investigating two specimens collected at Matsugasaki in Kawamoto-cho, Ochi-gun, Shimane Prefecture by Yoshinori Sugimura (SA no. 24409 & 24410), in the Herbarium of Sanbe Shizenkan (Shimane Nature Museum of Mt. Sanbe), it was speculated that they are the hybrid, although both were identified as Fritillaria amabilis.
The author thanks Mr. Masahito Inoue and Makoto Tanaka for their guidance to the field, Mr. Masahito Inoue for providing images of herbarium specimens, Dr. Hidenori Tachida for the information on matK gene of cpDNA, Mr. Ko Seto and Dr. Yasuro Kadono for their valuable comments, and Dr. Madjit Hakki for his corrections of my English manuscript.
