Distribution: island of Rhodes, --------

With regard to these localities it should be noted that among the Greeks the prophet Elijah (Hagios Elias) is the patron Saint of mountains (cf. Hastings, Dict. Bible, I, 691:1898) and consequently many mountains in Greece and the Aegean islands nowadays bear his name." (Stearn, loc. cit. 1941).

Description: Stem glabrous, reddish, 28-35 cm. Lower leaves biternate. with all or nearly all leaflets divided, totalling 9-29 divisions; terminal leaflet of each trichotomy deeply trifurcate, lateral leaflets usually bifurcate, entire or divided into 3 or 4 lobes. Leaflets and segments ovate to oblong-elliptic or lanceolate, acute to shortly acuminate, thin textured, 2.5-1 cm long, 0.7-3.7 cm broad, green above, paler below, glabrous, subpetiolate or sessile. Flowers c. 7-8 cm across. Petals 6-8, obovate-orbicula, white. Filaments red. Carpels 2-5, tomentose. Style c. 10 mm; stigmatic area 2-2.75 mm broad, strongly circinnate in upper 3/4. Fl. February - April 2 n:10.

Type: (Rhodes) Nadelholzwälder am monte Profitze, c. 6000 m, 1938, Engelhardt & Landby (K!).

DODEKANISOS (Dodecanese): Rhodes (Rhodes): -----------

Habitat: Forest of Cupressus semoervirens var. horizontalis on limestone, rarely in phrygana. Altitude 350-630 m.

This is closely allied to P. clusii of Crete and Karpathos but well distinguished in leaf characters.

Specimens collected in fruit on Rhodes by Emile Bourgeau in 1870 made known the existence of a wild peony on the island but its flowers were unknown until 1938 when Mrs Elsa Landby, a Swedish lady living at Eynsford, Kent, England, sent a pressed flowering specimen to Kew for identification. She had brought back a plant for her garden. Unfortunately she died not long afterwards but her husband kindly permitted Stearn to fix root-tips at Eynsford from which L.F. LaCour determined it as having 2 n:10, hence a diploid; Tzanoudakis has confirmed this number. E.A. Bowles had earlier received a plant from Rhodes, stated to be white-flowered, in 1930; he managed to keep it alive for many years hut it never throve and never flowered again. Convinced of its distinctness Stearn in 1941 described it as a new species.

6. P.clusii F.C. Stern, Bot. Mag. 162 :t. 9594 (1940) (P. officinalis var. glabra (Boiss.) Hayek). Stems 20-30 cm. Lower leaves with 30 or more narrowly oblong to narrowly elliptical, acute segments, glabrous above and beneath, or slightly pubescent beneath. Flowers 7—10 cm in diameter, white, rarely flushed with pink. Filaments pink. Follicles 2—5, c. 3 cm, densely tomentose. 2n = 10, 20. Kriti and Karpathos. Cr.

Outside Europe, known only from the E. Aegean islands, where the plants have been distinguished as P. rhodia Stearn, Gard. Chron., ser. 3, 110: 159 (1941) (subsp. rhodia (Stearn) Tzan.).
