90 THE INFLORESCENCE. 
310. Extra axillary, or lateral, when the flower grows 
from the side of the origin of a leaf, as in Common Garden 
Nightshade (Solanum nigrum). 
311. Epiphyllous, when the flower grows on the surface of 
the leaf, as in Butchers Broom (Ruscus aculeatus). 
312. Terminal, when the axis or stalk terminates in a 
flower or bunch of flowers, as Paeony. 
The flowers are said to be in the form of 4 
313, Sprxe (spica), when they are sessile and placed sim- 
ply along a common stalk or axis, as in Plantain (Plantago), 
the genus Orchis, Wheat (Triticum hybernum), Great Mul- 
lein (Verbascum thapsus.) 
314. The term also has been applied to flowers in this form 
when the peduncle is very short, as Spiked Speedwell (Vero- 
nica spicata), which Dr. Hooker calls a spicate raceme (318); 
Common Lavender(Lavandula spicata), Foxglove ( Digitalis,) 
&e. 
315. The spike generally grows erect ; and the expansion 
of its different flowers is progressive, the lower ones frequent- 
ly having faded before the upper ones have opened. : 
316. The term spikelet (spicula) is applied to Grasses with 
many florets within one calyx (Smith), set on a little stalk, 
which is the spikelet, as in Meadow Grass (Poa) Ryegrass, 
(Lolium Perenne.) . 
317. The spike is sometimes unilateral (secunda), the 
flowers all leaning to one side, as in Matgrass(Nardus stricta.) 
The Flowers are in the form of a 
318. Raceme, or cluster, when they are numerous, distant, 
peduncled, and arranged along a common stalk, differing 
_ from the spiked form only in having peduncles, and in being 
more distant, as Common Red Currant (Ribes rubrum ; See 
‘Fig. 15.) Barberry (Berberis oulgaris).
