THIS little green-flowered shrub at first sight bears a strong resemblance to the E. clavata, but on close inspection will be found to differ in almost every particular, except colour, from that species. We first observed the E. viridiflora, at the Hammersmith nursery, in 1820, at which period there was only one plant of it that had been raised from Cape seed: at present there are many other plants of it, that will, upon comparison, be found to differ from the E. clavata, not only in the exterior, but also in the interior of the blossom, as the anthers in this species are minutely bicornute, and in the other beardless.
