A Grammatical Dictionary of Botanical Latin

 
radians,-antis (part.B): radiant, radiating, spreading straight outwards from a common center; emitting rays; “spreading from a common point, or from the circumference of a circle. Also forming apparent rays in the cirumference of a circle by the enlargement of the exterior parts, as the outer florets in the umbels of many umbelliferous plants” (Lindley); “spreading straight outwards from a common center” (Stearn); beaming, shining, as the rays of the sun [> L. radio,-avi,-atum, 1. to furnish with spokes; to furnish with beams, irradiate];

- lumina solis radiantia, the shining lights of the sun; sidera radiantia, the stars shining.

- folia nervis apicem versus atque basim versus utroque radiantia, leaves with nerves toward the apex and also toward the base in both directions radiating.

- (algae) fila fasciculata, ex uno puncto 5, 4 vel adhuc plura radiantia, maxime rigida & fragilia (Agardh), the threads fasciculate, 5, 4 or more besides radiating from one point, most rigid and fragile.

- [Oscillatoria limosa] filis caerulescenti-viridibus, in stratum gelatinosum margine longe radians atrovirens intertextis (Agardh), with bluish-green threads, interwoven into a black-green gelatinous layer, radiating far from the margin.

- (algae) vividissime oscillantia, citissime elongantur, & crescendo oscillandoque radiantia, radiis saepe uncialibus (Agardh), very vigorously oscillating, very quickly elongated, and by growing and oscillating, radiating out, with the rays often an inch.

- stigmata distincta, v. disco epigyno (ovarii apice disciformi) adnata, radiantia v. annularia (B&H), stigmas distinct [i.e. separate], or adnate to the epigynous disc (to the disciform apex of the ovary), radiating or annular [i.e. in a ring or rings].

- stigmatis lobi 4 - 6 , supra verticem depressimi styli brevissimi radiantes. (B&H), the lobes of the stigma 4-6, radiating [i.e. outwards]. above the depressed apex of the very short style

- lobis a centro radiantibus placentis oppositis (B&H), with the lobes radiating from the center, opposite the placentas.

- bracteae nunc appendicibus scariosis coloratis erectis v. radiantibus terminatae (B&H), the bracts sometimes terminated by scarious, colored erect or radiating appendages.

- carpella 10-20 coalita in baccam spuriam multilocularem stigmatibusque radiantibus coronalam (DeCandolle), carpels 10-20 fused into a multilocular spurious berry and crowned with the radiating stigmas.

- fructus compressi orbiculares, striis radiantibas margine notati (DeCandolle), the fruits compressed, orbicular, marked with radiating streaks at the margin.

NOTE: [Umbelliferae] flores in capitulis v. spicis densis sessiles, singuli bracteis subtensi, bracteis exterioribus involucrum nunc spinosum nunc stellato-radians rarius floribus brevius constituentibus. (B&H), flowers sessile in small heads or dense spikes, a single one subtended by bracts, the outer bracts constituting the involucre sometimes spinose, sometimes stellate-radiating more rarely shorter than the flowers.

NOTE: in the Umbelliferae, B&H seems to use ‘radians’ as ‘umbellate’ or umbellate-branched.

Bifora radians;Coriandrum radians; Echinophora radians; Stellaria radians; Wylia radians; Zosima radians

 

A work in progress, presently with preliminary A through R, and S, and with S (in part) through Z essentially completed.
