Lupinus nanus. Aug. 5. 62 (from Vaucher)
When mature or nearly mature flower opens, 5 long arrow like anthers may be seen low down within keel which have shed pollen & which has been forced, (I suppose by growth of pistil with its stigma surrounded by radiating hairs) with mass at end of keel— When latter & keel-like petals are depressed, the a woosh of pollen is forced out.— There are also 5 other small testes-like anthers (4 long & 1 short) nearer end of keel, which maturing pollen, but little later: I doubt whether this is at first forced out by stigma.—
Pollen identical in both sets of anthers— Pollen of small anthers small in quantity, vast in others.
